@description\n * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.\n *\n * If jQuery is available, `angular.element` is an alias for the\n * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`\n * delegates to AngularJS's built-in subset of jQuery, called \"jQuery lite\" or **jqLite**.\n *\n * jqLite is a tiny, API-compatible subset of jQuery that allows\n * AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most\n * commonly needed functionality with the goal of having a very small footprint.\n *\n * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the\n * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a\n * specific version of jQuery if multiple versions exist on the page.\n *\n *

**Note:** All element references in AngularJS are always wrapped with jQuery or\n * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.

\n *\n *

**Note:** Keep in mind that this function will not find elements\n * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`\n * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

\n *\n * ## AngularJS's jqLite\n * jqLite provides only the following jQuery methods:\n *\n * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument\n * - [`after()`](http://api.jquery.com/after/)\n * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements\n * so will not work correctly when invoked on a jqLite object containing more than one DOM node\n * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData\n * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n * - [`clone()`](http://api.jquery.com/clone/)\n * - [`contents()`](http://api.jquery.com/contents/)\n * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.\n * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.\n * - [`data()`](http://api.jquery.com/data/)\n * - [`detach()`](http://api.jquery.com/detach/)\n * - [`empty()`](http://api.jquery.com/empty/)\n * - [`eq()`](http://api.jquery.com/eq/)\n * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n * - [`hasClass()`](http://api.jquery.com/hasClass/)\n * - [`html()`](http://api.jquery.com/html/)\n * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter\n * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n * - [`prepend()`](http://api.jquery.com/prepend/)\n * - [`prop()`](http://api.jquery.com/prop/)\n * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)\n * - [`remove()`](http://api.jquery.com/remove/)\n * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes\n * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument\n * - [`removeData()`](http://api.jquery.com/removeData/)\n * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n * - [`text()`](http://api.jquery.com/text/)\n * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument\n * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers\n * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter\n * - [`val()`](http://api.jquery.com/val/)\n * - [`wrap()`](http://api.jquery.com/wrap/)\n *\n * jqLite also provides a method restoring pre-1.8 insecure treatment of XHTML-like tags.\n * This legacy behavior turns input like `

` to `

`\n * instead of `

` like version 1.8 & newer do. To restore it, invoke:\n * ```js\n * angular.UNSAFE_restoreLegacyJqLiteXHTMLReplacement();\n * ```\n * Note that this only patches jqLite. If you use jQuery 3.5.0 or newer, please read the\n * [jQuery 3.5 upgrade guide](https://jquery.com/upgrade-guide/3.5/) for more details\n * about the workarounds.\n *\n * ## jQuery/jqLite Extras\n * AngularJS also provides the following additional methods and events to both jQuery and jqLite:\n *\n * ### Events\n * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM\n * element before it is removed.\n *\n * ### Methods\n * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n * retrieves controller associated with the `ngController` directive. If `name` is provided as\n * camelCase directive name, then the controller for this directive will be retrieved (e.g.\n * `'ngModel'`).\n * - `injector()` - retrieves the injector of the current element or its parent.\n * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to\n * be enabled.\n * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the\n * current element. This getter should be used only on elements that contain a directive which starts a new isolate\n * scope. Calling `scope()` on this element always returns the original non-isolate scope.\n * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.\n * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n * parent element is reached.\n *\n * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See\n * https://github.com/angular/angular.js/issues/14251 for more information.\n *\n * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n * @returns {Object} jQuery object.\n */\n\nJQLite.expando = 'ng339';\n\nvar jqCache = JQLite.cache = {},\n jqId = 1;\n\n/*\n * !!!

This is done\n * by converting the function into a string using `toString()` method and extracting the argument\n * names.\n * ```js\n * // Given\n * function MyController($scope, $route) {\n * // ...\n * }\n *\n * // Then\n * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);\n * ```\n *\n * You can disallow this method by using strict injection mode.\n *\n * This method does not work with code minification / obfuscation.

In these situations using the array notation to specify the dependencies in\n * a way that survives minification is a better choice:\n *\n * ```js\n * // We wish to write this (not minification / obfuscation safe)\n * injector.invoke(function($compile, $rootScope) {\n * // ...\n * });\n *\n * // We are forced to write break inlining\n * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {\n * // ...\n * };\n * tmpFn.$inject = ['$compile', '$rootScope'];\n * injector.invoke(tmpFn);\n *\n * // To better support inline function the inline annotation is supported\n * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {\n * // ...\n * }]);\n *\n * // Therefore\n * expect(injector.annotate(\n * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])\n * ).toEqual(['$compile', '$rootScope']);\n * ```\n *\n * @param {Function|Array.} fn Function for which dependent service names need to\n * be retrieved as described above.\n *\n * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.\n *\n * @returns {Array.} The names of the services which the function requires.\n */\n/**\n * @ngdoc method\n * @name $injector#loadNewModules\n *\n * @description\n *\n * **This is a dangerous API, which you use at your own risk!**\n *\n * Add the specified modules to the current injector.\n *\n * This method will add each of the injectables to the injector and execute all of the config and run\n * blocks for each module passed to the method.\n *\n * If a module has already been loaded into the injector then it will not be loaded again.\n *\n * * The application developer is responsible for loading the code containing the modules; and for\n * ensuring that lazy scripts are not downloaded and executed more often that desired.\n * * Previously compiled HTML will not be affected by newly loaded directives, filters and components.\n * * Modules cannot be unloaded.\n *\n * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded\n * into the injector, which may indicate whether the script has been executed already.\n *\n * @example\n * Here is an example of loading a bundle of modules, with a utility method called `getScript`:\n *\n * ```javascript\n * app.factory('loadModule', function($injector) {\n * return function loadModule(moduleName, bundleUrl) {\n * return getScript(bundleUrl).then(function() { $injector.loadNewModules([moduleName]); });\n * };\n * })\n * ```\n *\n * @param {Array=} mods an array of modules to load into the application.\n * Each item in the array should be the name of a predefined module or a (DI annotated)\n * function that will be invoked by the injector as a `config` block.\n * See: {@link angular.module modules}\n */\n\n\n/**\n * @ngdoc service\n * @name $provide\n *\n * @description\n *\n * The {@link auto.$provide $provide} service has a number of methods for registering components\n * with the {@link auto.$injector $injector}.

\n * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from\n * the top of the page to the element's bottom will be used as offset.

\n * **Note:** This document is an in-depth reference of all directive options.\n * For a gentle introduction to directives with examples of common use cases,\n * see the {@link guide/directive directive guide}.\n *

\n *\n * ## Comprehensive Directive API\n *\n * There are many different options for a directive.\n *\n * The difference resides in the return value of the factory function.\n * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}\n * that defines the directive properties, or just the `postLink` function (all other properties will have\n * the default values).\n *\n *

\n * **Best Practice:** It's recommended to use the \"directive definition object\" form.\n *

\n *\n * Here's an example directive declared with a Directive Definition Object:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * {@link $compile#-priority- priority}: 0,\n * {@link $compile#-template- template}: '

', // or // function(tElement, tAttrs) { ... },\n * // or\n * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },\n * {@link $compile#-transclude- transclude}: false,\n * {@link $compile#-restrict- restrict}: 'A',\n * {@link $compile#-templatenamespace- templateNamespace}: 'html',\n * {@link $compile#-scope- scope}: false,\n * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },\n * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',\n * {@link $compile#-bindtocontroller- bindToController}: false,\n * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],\n * {@link $compile#-multielement- multiElement}: false,\n * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {\n * return {\n * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },\n * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }\n * }\n * // or\n * // return function postLink( ... ) { ... }\n * },\n * // or\n * // {@link $compile#-link- link}: {\n * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },\n * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }\n * // }\n * // or\n * // {@link $compile#-link- link}: function postLink( ... ) { ... }\n * };\n * return directiveDefinitionObject;\n * });\n * ```\n *\n *

\n * **Note:** Any unspecified options will use the default value. You can see the default values below.\n *

\n *\n * Therefore the above can be simplified as:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * link: function postLink(scope, iElement, iAttrs) { ... }\n * };\n * return directiveDefinitionObject;\n * // or\n * // return function postLink(scope, iElement, iAttrs) { ... }\n * });\n * ```\n *\n * ### Life-cycle hooks\n * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the\n * directive:\n * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and\n * had their bindings initialized (and before the pre & post linking functions for the directives on\n * this element). This is a good place to put initialization code for your controller.\n * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The\n * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an\n * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a\n * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will\n * also be called when your bindings are initialized.\n * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on\n * changes. Any actions that you wish to take in response to the changes that you detect must be\n * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook\n * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not\n * be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;\n * if detecting changes, you must store the previous value(s) for comparison to the current values.\n * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing\n * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in\n * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent\n * components will have their `$onDestroy()` hook called before child components.\n * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link\n * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.\n * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since\n * they are waiting for their template to load asynchronously and their own compilation and linking has been\n * suspended until that occurs.\n *\n * #### Comparison with life-cycle hooks in the new Angular\n * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are\n * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:\n *\n * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.\n * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.\n * In Angular you can only define hooks on the prototype of the Component class.\n * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to\n * `ngDoCheck` in Angular.\n * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be\n * propagated throughout the application.\n * Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an\n * error or do nothing depending upon the state of `enableProdMode()`.\n *\n * #### Life-cycle hook examples\n *\n * This example shows how you can check for mutations to a Date object even though the identity of the object\n * has not changed.\n *\n * \n * \n * angular.module('do-check-module', [])\n * .component('app', {\n * template:\n * 'Month: ' +\n * 'Date: {{ $ctrl.date }}' +\n * '',\n * controller: function() {\n * this.date = new Date();\n * this.month = this.date.getMonth();\n * this.updateDate = function() {\n * this.date.setMonth(this.month);\n * };\n * }\n * })\n * .component('test', {\n * bindings: { date: '<' },\n * template:\n * '

{{ $ctrl.log | json }}

',\n * controller: function() {\n * var previousValue;\n * this.log = [];\n * this.$doCheck = function() {\n * var currentValue = this.date && this.date.valueOf();\n * if (previousValue !== currentValue) {\n * this.log.push('doCheck: date mutated: ' + this.date);\n * previousValue = currentValue;\n * }\n * };\n * }\n * });\n * \n * \n * \n * \n * \n *\n * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the\n * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large\n * arrays or objects can have a negative impact on your application performance.)\n *\n * \n * \n *

\n * \n * \n *

\n * \n * \n * angular.module('do-check-module', [])\n * .component('test', {\n * bindings: { items: '<' },\n * template:\n * '

',\n * controller: function() {\n * this.log = [];\n *\n * this.$doCheck = function() {\n * if (this.items_ref !== this.items) {\n * this.log.push('doCheck: items changed');\n * this.items_ref = this.items;\n * }\n * if (!angular.equals(this.items_clone, this.items)) {\n * this.log.push('doCheck: items mutated');\n * this.items_clone = angular.copy(this.items);\n * }\n * };\n * }\n * });\n * \n * \n *\n *\n * ### Directive Definition Object\n *\n * The directive definition object provides instructions to the {@link ng.$compile\n * compiler}. The attributes are:\n *\n * #### `multiElement`\n * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between\n * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them\n * together as the directive elements. It is recommended that this feature be used on directives\n * which are not strictly behavioral (such as {@link ngClick}), and which\n * do not manipulate or replace child nodes (such as {@link ngInclude}).\n *\n * #### `priority`\n * When there are multiple directives defined on a single DOM element, sometimes it\n * is necessary to specify the order in which the directives are applied. The `priority` is used\n * to sort the directives before their `compile` functions get called. Priority is defined as a\n * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n * are also run in priority order, but post-link functions are run in reverse order. The order\n * of directives with the same priority is undefined. The default priority is `0`.\n *\n * #### `terminal`\n * If set to true then the current `priority` will be the last set of directives\n * which will execute (any directives at the current priority will still execute\n * as the order of execution on same `priority` is undefined). Note that expressions\n * and other directives used in the directive's template will also be excluded from execution.\n *\n * #### `scope`\n * The scope property can be `false`, `true`, or an object:\n *\n * * **`false` (default):** No scope will be created for the directive. The directive will use its\n * parent's scope.\n *\n * * **`true`:** A new child scope that prototypically inherits from its parent will be created for\n * the directive's element. If multiple directives on the same element request a new scope,\n * only one new scope is created.\n *\n * * **`{...}` (an object hash):** A new \"isolate\" scope is created for the directive's template.\n * The 'isolate' scope differs from normal scope in that it does not prototypically\n * inherit from its parent scope. This is useful when creating reusable components, which should not\n * accidentally read or modify data in the parent scope. Note that an isolate scope\n * directive without a `template` or `templateUrl` will not apply the isolate scope\n * to its children elements.\n *\n * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the\n * directive's element. These local properties are useful for aliasing values for templates. The keys in\n * the object hash map to the name of the property on the isolate scope; the values define how the property\n * is bound to the parent scope, via matching attributes on the directive's element:\n *\n * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n * always a string since DOM attributes are strings. If no `attr` name is specified then the\n * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,\n * the directive's scope property `localName` will reflect the interpolated value of `hello\n * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's\n * scope. The `name` is read from the parent scope (not the directive's scope).\n *\n * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression\n * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.\n * If no `attr` name is specified then the attribute name is assumed to be the same as the local\n * name. Given `` and the isolate scope definition `scope: {\n * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the\n * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in\n * `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute\n * isn't optional and doesn't exist, an exception\n * ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes\n * to the local value, since it will be impossible to sync them back to the parent scope.\n *\n * By default, the {@link ng.$rootScope.Scope#$watch `$watch`}\n * method is used for tracking changes, and the equality check is based on object identity.\n * However, if an object literal or an array literal is passed as the binding expression, the\n * equality check is done by value (using the {@link angular.equals} function). It's also possible\n * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection\n * `$watchCollection`}: use `=*` or `=*attr`\n *\n * * `<` or `` and directive definition of\n * `scope: { localModel:'` and the isolate scope definition `scope: {\n * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for\n * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope\n * via an expression to the parent scope. This can be done by passing a map of local variable names\n * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`\n * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.\n *\n * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.\n * The marker must come after the mode and before the attribute name.\n * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.\n * This is useful to refine the interface directives provide.\n * One subtle difference between optional and non-optional happens **when the binding attribute is not\n * set**:\n * - the binding is optional: the property will not be defined\n * - the binding is not optional: the property is defined\n *\n * ```js\n *app.directive('testDir', function() {\n return {\n scope: {\n notoptional: '=',\n optional: '=?',\n },\n bindToController: true,\n controller: function() {\n this.$onInit = function() {\n console.log(this.hasOwnProperty('notoptional')) // true\n console.log(this.hasOwnProperty('optional')) // false\n }\n }\n }\n })\n *```\n *\n *\n * ##### Combining directives with different scope defintions\n *\n * In general it's possible to apply more than one directive to one element, but there might be limitations\n * depending on the type of scope required by the directives. The following points will help explain these limitations.\n * For simplicity only two directives are taken into account, but it is also applicable for several directives:\n *\n * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope\n * * **child scope** + **no scope** => Both directives will share one single child scope\n * * **child scope** + **child scope** => Both directives will share one single child scope\n * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use\n * its parent's scope\n * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot\n * be applied to the same element.\n * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives\n * cannot be applied to the same element.\n *\n *\n * #### `bindToController`\n * This property is used to bind scope properties directly to the controller. It can be either\n * `true` or an object hash with the same format as the `scope` property.\n *\n * When an isolate scope is used for a directive (see above), `bindToController: true` will\n * allow a component to have its properties bound to the controller, rather than to scope.\n *\n * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller\n * properties. You can access these bindings once they have been initialized by providing a controller method called\n * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings\n * initialized.\n *\n * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.\n * This will set up the scope bindings to the controller directly. Note that `scope` can still be used\n * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate\n * scope (useful for component directives).\n *\n * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.\n *\n *\n * #### `controller`\n * Controller constructor function. The controller is instantiated before the\n * pre-linking phase and can be accessed by other directives (see\n * `require` attribute). This allows the directives to communicate with each other and augment\n * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n *\n * * `$scope` - Current scope associated with the element\n * * `$element` - Current element\n * * `$attrs` - Current attributes object for the element\n * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:\n * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:\n * * `scope`: (optional) override the scope.\n * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.\n * * `futureParentElement` (optional):\n * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.\n * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.\n * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)\n * and when the `cloneLinkingFn` is passed,\n * as those elements need to created and cloned in a special way when they are defined outside their\n * usual containers (e.g. like `

`\n * * `C` - Class: `

`\n * * `M` - Comment: ``\n *\n *\n * #### `templateNamespace`\n * String representing the document type used by the markup in the template.\n * AngularJS needs this information as those elements need to be created and cloned\n * in a special way when they are defined outside their usual containers like `

`.\n * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`\n * function api below) and returns a string value.\n *\n *\n * #### `templateUrl`\n * This is similar to `template` but the template is loaded from the specified URL, asynchronously.\n *\n * Because template loading is asynchronous the compiler will suspend compilation of directives on that element\n * for later when the template has been resolved. In the meantime it will continue to compile and link\n * sibling and parent elements as though this element had not contained any directives.\n *\n * The compiler does not suspend the entire compilation to wait for templates to be loaded because this\n * would result in the whole app \"stalling\" until all templates are loaded asynchronously - even in the\n * case when only one deeply nested directive has `templateUrl`.\n *\n * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}.\n *\n * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n * a string value representing the url. In either case, the template URL is passed through {@link\n * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n *\n *\n * #### `replace`\n *

\n * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).\n *

\n *\n * Specifies what the template should replace. Defaults to `false`.\n *\n * * `true` - the template will replace the directive's element.\n * * `false` - the template will replace the contents of the directive's element.\n *\n * The replacement process migrates all of the attributes / classes from the old element to the new\n * one. See the {@link guide/directive#template-expanding-directive\n * Directives Guide} for an example.\n *\n * There are very few scenarios where element replacement is required for the application function,\n * the main one being reusable custom components that are used within SVG contexts\n * (because SVG doesn't work with custom elements in the DOM tree).\n *\n * #### `transclude`\n * Extract the contents of the element where the directive appears and make it available to the directive.\n * The contents are compiled and provided to the directive as a **transclusion function**. See the\n * {@link $compile#transclusion Transclusion} section below.\n *\n *\n * #### `compile`\n *\n * ```js\n * function compile(tElement, tAttrs, transclude) { ... }\n * ```\n *\n * The compile function deals with transforming the template DOM. Since most directives do not do\n * template transformation, it is not used often. The compile function takes the following arguments:\n *\n * * `tElement` - template element - The element where the directive has been declared. It is\n * safe to do template transformation on the element and child elements only.\n *\n * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n * between all directive compile functions.\n *\n * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n *\n *

\n * **Note:** The template instance and the link instance may be different objects if the template has\n * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n * should be done in a linking function rather than in a compile function.\n *

\n\n *

\n * **Note:** The compile function cannot handle directives that recursively use themselves in their\n * own templates or compile functions. Compiling these directives results in an infinite loop and\n * stack overflow errors.\n *\n * This can be avoided by manually using `$compile` in the postLink function to imperatively compile\n * a directive's template instead of relying on automatic template compilation via `template` or\n * `templateUrl` declaration or manual compilation inside the compile function.\n *

\n *\n *

\n * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n * e.g. does not know about the right outer scope. Please use the transclude function that is passed\n * to the link function instead.\n *

\n\n * A compile function can have a return value which can be either a function or an object.\n *\n * * returning a (post-link) function - is equivalent to registering the linking function via the\n * `link` property of the config object when the compile function is empty.\n *\n * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n * control when a linking function should be called during the linking phase. See info about\n * pre-linking and post-linking functions below.\n *\n *\n * #### `link`\n * This property is used only if the `compile` property is not defined.\n *\n * ```js\n * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n * ```\n *\n * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n * executed after the template has been cloned. This is where most of the directive logic will be\n * put.\n *\n * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n * directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n *\n * * `iElement` - instance element - The element where the directive is to be used. It is safe to\n * manipulate the children of the element only in `postLink` function since the children have\n * already been linked.\n *\n * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n * between all directive linking functions.\n *\n * * `controller` - the directive's required controller instance(s) - Instances are shared\n * among all directives, which allows the directives to use the controllers as a communication\n * channel. The exact value depends on the directive's `require` property:\n * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one\n * * `string`: the controller instance\n * * `array`: array of controller instances\n *\n * If a required controller cannot be found, and it is optional, the instance is `null`,\n * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.\n *\n * Note that you can also require the directive's own controller - it will be made available like\n * any other controller.\n *\n * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n * This is the same as the `$transclude` parameter of directive controllers,\n * see {@link ng.$compile#-controller- the controller section for details}.\n * `function([scope], cloneLinkingFn, futureParentElement)`.\n *\n * #### Pre-linking function\n *\n * Executed before the child elements are linked. Not safe to do DOM transformation since the\n * compiler linking function will fail to locate the correct elements for linking.\n *\n * #### Post-linking function\n *\n * Executed after the child elements are linked.\n *\n * Note that child elements that contain `templateUrl` directives will not have been compiled\n * and linked since they are waiting for their template to load asynchronously and their own\n * compilation and linking has been suspended until that occurs.\n *\n * It is safe to do DOM transformation in the post-linking function on elements that are not waiting\n * for their async templates to be resolved.\n *\n *\n * ### Transclusion\n *\n * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and\n * copying them to another part of the DOM, while maintaining their connection to the original AngularJS\n * scope from where they were taken.\n *\n * Transclusion is used (often with {@link ngTransclude}) to insert the\n * original contents of a directive's element into a specified place in the template of the directive.\n * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded\n * content has access to the properties on the scope from which it was taken, even if the directive\n * has isolated scope.\n * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.\n *\n * This makes it possible for the widget to have private state for its template, while the transcluded\n * content has access to its originating scope.\n *\n *

\n * **Note:** When testing an element transclude directive you must not place the directive at the root of the\n * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives\n * Testing Transclusion Directives}.\n *

\n *\n * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the\n * directive's element, the entire element or multiple parts of the element contents:\n *\n * * `true` - transclude the content (i.e. the child nodes) of the directive's element.\n * * `'element'` - transclude the whole of the directive's element including any directives on this\n * element that are defined at a lower priority than this directive. When used, the `template`\n * property is ignored.\n * * **`{...}` (an object hash):** - map elements of the content onto transclusion \"slots\" in the template.\n *\n * **Multi-slot transclusion** is declared by providing an object for the `transclude` property.\n *\n * This object is a map where the keys are the name of the slot to fill and the value is an element selector\n * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)\n * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).\n *\n * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}.\n *\n * If the element selector is prefixed with a `?` then that slot is optional.\n *\n * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to\n * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.\n *\n * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements\n * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call\n * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and\n * injectable into the directive's controller.\n *\n *\n * #### Transclusion Functions\n *\n * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion\n * function** to the directive's `link` function and `controller`. This transclusion function is a special\n * **linking function** that will return the compiled contents linked to a new transclusion scope.\n *\n *

\n * If you are just using {@link ngTransclude} then you don't need to worry about this function, since\n * ngTransclude will deal with it for us.\n *

\n *\n * If you want to manually control the insertion and removal of the transcluded content in your directive\n * then you must use this transclude function. When you call a transclude function it returns a jqLite/JQuery\n * object that contains the compiled DOM, which is linked to the correct transclusion scope.\n *\n * When you call a transclusion function you can pass in a **clone attach function**. This function accepts\n * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded\n * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.\n *\n *

\n * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function\n * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.\n *

\n *\n * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone\n * attach function**:\n *\n * ```js\n * var transcludedContent, transclusionScope;\n *\n * $transclude(function(clone, scope) {\n * element.append(clone);\n * transcludedContent = clone;\n * transclusionScope = scope;\n * });\n * ```\n *\n * Later, if you want to remove the transcluded content from your DOM then you should also destroy the\n * associated transclusion scope:\n *\n * ```js\n * transcludedContent.remove();\n * transclusionScope.$destroy();\n * ```\n *\n *

\n * **Best Practice**: if you intend to add and remove transcluded content manually in your directive\n * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),\n * then you are also responsible for calling `$destroy` on the transclusion scope.\n *

\n *\n * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}\n * automatically destroy their transcluded clones as necessary so you do not need to worry about this if\n * you are simply using {@link ngTransclude} to inject the transclusion into your directive.\n *\n *\n * #### Transclusion Scopes\n *\n * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion\n * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed\n * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it\n * was taken.\n *\n * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look\n * like this:\n *\n * ```html\n *

\n *

\n * ```\n *\n * The `$parent` scope hierarchy will look like this:\n *\n ```\n - $rootScope\n - isolate\n - transclusion\n ```\n *\n * but the scopes will inherit prototypically from different scopes to their `$parent`.\n *\n ```\n - $rootScope\n - transclusion\n - isolate\n ```\n *\n *\n * ### Attributes\n *\n * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n * `link()` or `compile()` functions. It has a variety of uses.\n *\n * * *Accessing normalized attribute names:* Directives like `ngBind` can be expressed in many ways:\n * `ng:bind`, `data-ng-bind`, or `x-ng-bind`. The attributes object allows for normalized access\n * to the attributes.\n *\n * * *Directive inter-communication:* All directives share the same instance of the attributes\n * object which allows the directives to use the attributes object as inter directive\n * communication.\n *\n * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n * allowing other directives to read the interpolated value.\n *\n * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n * that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n * the only way to easily get the actual value because during the linking phase the interpolation\n * hasn't been evaluated yet and so the value is at this time set to `undefined`.\n *\n * ```js\n * function linkingFn(scope, elm, attrs, ctrl) {\n * // get the attribute value\n * console.log(attrs.ngModel);\n *\n * // change the attribute\n * attrs.$set('ngModel', 'new value');\n *\n * // observe changes to interpolated attribute\n * attrs.$observe('ngModel', function(value) {\n * console.log('ngModel has changed value to ' + value);\n * });\n * }\n * ```\n *\n * ## Example\n *\n *

\n * **Note**: Typically directives are registered with `module.directive`. The example below is\n * to illustrate how `$compile` works.\n *

\n *\n \n \n \n

\n
\n
\n

\n \n \n it('should auto compile', function() {\n var textarea = $('textarea');\n var output = $('div[compile]');\n // The initial state reads 'Hello AngularJS'.\n expect(output.getText()).toBe('Hello AngularJS');\n textarea.clear();\n textarea.sendKeys('{{name}}!');\n expect(output.getText()).toBe('AngularJS!');\n });\n \n \n\n *\n *\n * @param {string|DOMElement} element Element or HTML string to compile into a template function.\n * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.\n *\n *

\n * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it\n * e.g. will not use the right outer scope. Please pass the transclude function as a\n * `parentBoundTranscludeFn` to the link function instead.\n *

\n *\n * @param {number} maxPriority only apply directives lower than given priority (Only effects the\n * root element(s), not their children)\n * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template\n * (a DOM element/tree) to a scope. Where:\n *\n * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n * `template` and call the `cloneAttachFn` function allowing the caller to attach the\n * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n * called as:
`cloneAttachFn(clonedElement, scope)` where:\n *\n * * `clonedElement` - is a clone of the original `element` passed into the compiler.\n * * `scope` - is the current scope with which the linking function is working with.\n *\n * * `options` - An optional object hash with linking options. If `options` is provided, then the following\n * keys may be used to control linking behavior:\n *\n * * `parentBoundTranscludeFn` - the transclude function made available to\n * directives; if given, it will be passed through to the link functions of\n * directives found in `element` during compilation.\n * * `transcludeControllers` - an object hash with keys that map controller names\n * to a hash with the key `instance`, which maps to the controller instance;\n * if given, it will make the controllers available to directives on the compileNode:\n * ```\n * {\n * parent: {\n * instance: parentControllerInstance\n * }\n * }\n * ```\n * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add\n * the cloned elements; only needed for transcludes that are allowed to contain non HTML\n * elements (e.g. SVG elements). See also the `directive.controller` property.\n *\n * Calling the linking function returns the element of the template. It is either the original\n * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n *\n * After linking the view is not updated until after a call to `$digest`, which typically is done by\n * AngularJS automatically.\n *\n * If you need access to the bound view, there are two ways to do it:\n *\n * - If you are not asking the linking function to clone the template, create the DOM element(s)\n * before you send them to the compiler and keep this reference around.\n * ```js\n * var element = angular.element('

');\n * $compile(element)(scope);\n * ```\n *\n * - if on the other hand, you need the element to be cloned, the view reference from the original\n * example would not point to the clone, but rather to the original template that was cloned. In\n * this case, you can access the clone either via the `cloneAttachFn` or the value returned by the\n * linking function:\n * ```js\n * var templateElement = angular.element('

');\n * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {\n * // Attach the clone to DOM document at the right place.\n * });\n *\n * // Now we have reference to the cloned DOM via `clonedElement`.\n * // NOTE: The `clonedElement` returned by the linking function is the same as the\n * // `clonedElement` passed to `cloneAttachFn`.\n * ```\n *\n *\n * For information on how the compiler works, see the\n * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.\n *\n * @knownIssue\n *\n * ### Double Compilation\n *\n Double compilation occurs when an already compiled part of the DOM gets\n compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,\n and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it\n section on double compilation} for an in-depth explanation and ways to avoid it.\n\n * @knownIssue\n\n ### Issues with `replace: true`\n *\n *

\n * **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,\n * mainly due to the issues listed here. It has been completely removed in the new Angular.\n *

\n *\n * #### Attribute values are not merged\n *\n * When a `replace` directive encounters the same attribute on the original and the replace node,\n * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of\n * the `style` attribute.\n * ```html\n * Original Node: \n * Replace Template: \n * Result: \n * ```\n *\n * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.\n * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:\n *\n * ```html\n * Original Node: \n * Replace Template: \n * Result: \n * ```\n *\n * See issue [#5695](https://github.com/angular/angular.js/issues/5695).\n *\n * #### Directives are not deduplicated before compilation\n *\n * When the original node and the replace template declare the same directive(s), they will be\n * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler\n * does not deduplicate them. In many cases, this is not noticeable, but e.g. {@link ngModel} will\n * attach `$formatters` and `$parsers` twice.\n *\n * See issue [#2573](https://github.com/angular/angular.js/issues/2573).\n *\n * #### `transclude: element` in the replace template root can have unexpected effects\n *\n * When the replace template has a directive at the root node that uses\n * {@link $compile#-transclude- `transclude: element`}, e.g.\n * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.\n * See the following issues:\n *\n * - Incorrect scope on replaced element:\n * [#9837](https://github.com/angular/angular.js/issues/9837)\n * - Different DOM between `template` and `templateUrl`:\n * [#10612](https://github.com/angular/angular.js/issues/14326)\n *\n */\n\n/**\n * @ngdoc directive\n * @name ngProp\n * @restrict A\n * @element ANY\n *\n * @usage\n *\n * ```html\n * \n * \n * ```\n *\n * or with uppercase letters in property (e.g. \"propName\"):\n *\n *\n * ```html\n * \n * \n * ```\n *\n *\n * @description\n * The `ngProp` directive binds an expression to a DOM element property.\n * `ngProp` allows writing to arbitrary properties by including\n * the property name in the attribute, e.g. `ng-prop-value=\"'my value'\"` binds 'my value' to\n * the `value` property.\n *\n * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives\n * handle the most common use cases (instead of the above example, you would use {@link ngValue}).\n *\n * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)\n * often use custom properties to hold data, and `ngProp` can be used to provide input to these\n * custom elements.\n *\n * ## Binding to camelCase properties\n *\n * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.\n * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so\n * `innerHTML` must be written as `ng-prop-inner_h_t_m_l=\"expression\"` (Note that this is just an\n * example, and for binding HTML {@link ngBindHtml} should be used.\n *\n * ## Security\n *\n * Binding expressions to arbitrary properties poses a security risk, as properties like `innerHTML`\n * can insert potentially dangerous HTML into the application, e.g. script tags that execute\n * malicious code.\n * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.\n * This means vulnerable properties require their content to be \"trusted\", based on the\n * context of the property. For example, the `innerHTML` is in the `HTML` context, and the\n * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to\n * this property are trusted as a `RESOURCE_URL`.\n *\n * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is\n * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for\n * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.\n *\n * In some cases you can also rely upon automatic sanitization of untrusted values - see below.\n *\n * Based on the context, other options may exist to mark a value as trusted / configure the behavior\n * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use\n * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()}\n * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}.\n *\n * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.\n *\n * ### HTML Sanitization\n *\n * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the\n * content.\n * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the\n * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to\n * `innerHTML`.\n *\n * @example\n * ### Binding to different contexts\n *\n * \n * \n * angular.module('exampleNgProp', [])\n * .component('main', {\n * templateUrl: 'main.html',\n * controller: function($sce) {\n * this.safeContent = 'Safe content';\n * this.unsafeContent = '';\n * this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);\n * }\n * });\n * \n * \n *

\n *

\n * Binding to a property without security context:\n *

\n * innerText (safeContent)\n *

\n *\n *

\n * \"Safe\" content that requires a security context will throw because the contents could potentially be dangerous ...\n *

\n * innerHTML (safeContent)\n *

\n *\n *

\n * ... so that actually dangerous content cannot be executed:\n *

\n * innerHTML (unsafeContent)\n *

\n *\n *

\n * ... but unsafe Content that has been trusted explicitly works - only do this if you are 100% sure!\n *

\n * innerHTML (trustedUnsafeContent)\n *

However, AngularJS does not support all events\n * (e.g. the `drop` event in the example above), and new events might be introduced in later DOM\n * standards.\n *\n * Another use-case for `ngOn` is listening to\n * [custom events](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)\n * fired by\n * [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements).\n *\n * ## Binding to camelCase properties\n *\n * Since HTML attributes are case-insensitive, camelCase properties like `myEvent` must be escaped.\n * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so\n * `myEvent` must be written as `ng-on-my_event=\"expression\"`.\n *\n * @example\n * ### Bind to built-in DOM events\n *\n * \n * \n * angular.module('exampleNgOn', [])\n * .component('main', {\n * templateUrl: 'main.html',\n * controller: function() {\n * this.clickCount = 0;\n * this.mouseoverCount = 0;\n *\n * this.loadingState = 0;\n * }\n * });\n * \n * \n *

While for simple usage patterns this doesn't matter much, for advanced usage\n * it is important to familiarize yourself with these APIs and the guarantees they provide.\n *\n *\n * ## General usage\n * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —\n * that is used to generate an HTTP request and returns a {@link ng.$q promise} that is\n * resolved (request success) or rejected (request failure) with a\n * {@link ng.$http#$http-returns response} object.\n *\n * ```js\n * // Simple GET request example:\n * $http({\n * method: 'GET',\n * url: '/someUrl'\n * }).then(function successCallback(response) {\n * // this callback will be called asynchronously\n * // when the response is available\n * }, function errorCallback(response) {\n * // called asynchronously if an error occurs\n * // or server returns response with an error status.\n * });\n * ```\n *\n *\n * ## Shortcut methods\n *\n * Shortcut methods are also available. All shortcut methods require passing in the URL, and\n * request data must be passed in for POST/PUT requests. An optional config can be passed as the\n * last argument.\n *\n * ```js\n * $http.get('/someUrl', config).then(successCallback, errorCallback);\n * $http.post('/someUrl', data, config).then(successCallback, errorCallback);\n * ```\n *\n * Complete list of shortcut methods:\n *\n * - {@link ng.$http#get $http.get}\n * - {@link ng.$http#head $http.head}\n * - {@link ng.$http#post $http.post}\n * - {@link ng.$http#put $http.put}\n * - {@link ng.$http#delete $http.delete}\n * - {@link ng.$http#jsonp $http.jsonp}\n * - {@link ng.$http#patch $http.patch}\n *\n *\n * ## Writing Unit Tests that use $http\n * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n * request using trained responses.\n *\n * ```\n * $httpBackend.expectGET(...);\n * $http.get(...);\n * $httpBackend.flush();\n * ```\n *\n * ## Setting HTTP Headers\n *\n * The $http service will automatically add certain HTTP headers to all requests. These defaults\n * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n * object, which currently contains this default configuration:\n *\n * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n * - Accept: application/json, text/plain, \\*/\\*\n * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n * - `Content-Type: application/json`\n * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n * - `Content-Type: application/json`\n *\n * To add or overwrite these defaults, simply add or remove a property from these configuration\n * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n * with the lowercased HTTP method name as the key, e.g.\n * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.\n *\n * The defaults can also be set at runtime via the `$http.defaults` object in the same\n * fashion. For example:\n *\n * ```\n * module.run(function($http) {\n * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';\n * });\n * ```\n *\n * In addition, you can supply a `headers` property in the config object passed when\n * calling `$http(config)`, which overrides the defaults without changing them globally.\n *\n * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,\n * Use the `headers` property, setting the desired header to `undefined`. For example:\n *\n * ```js\n * var req = {\n * method: 'POST',\n * url: 'http://example.com',\n * headers: {\n * 'Content-Type': undefined\n * },\n * data: { test: 'test' }\n * }\n *\n * $http(req).then(function(){...}, function(){...});\n * ```\n *\n * ## Transforming Requests and Responses\n *\n * Both requests and responses can be transformed using transformation functions: `transformRequest`\n * and `transformResponse`. These properties can be a single function that returns\n * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,\n * which allows you to `push` or `unshift` a new transformation function into the transformation chain.\n *\n *

\n * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.\n * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).\n * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest\n * function will be reflected on the scope and in any templates where the object is data-bound.\n * To prevent this, transform functions should have no side-effects.\n * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.\n *

\n *\n * ### Default Transformations\n *\n * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and\n * `defaults.transformResponse` properties. If a request does not provide its own transformations\n * then these will be applied.\n *\n * You can augment or replace the default transformations by modifying these properties by adding to or\n * replacing the array.\n *\n * AngularJS provides the following default transformations:\n *\n * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is\n * an array with one function that does the following:\n *\n * - If the `data` property of the request configuration object contains an object, serialize it\n * into JSON format.\n *\n * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is\n * an array with one function that does the following:\n *\n * - If XSRF prefix is detected, strip it (see Security Considerations section below).\n * - If the `Content-Type` is `application/json` or the response looks like JSON,\n * deserialize it using a JSON parser.\n *\n *\n * ### Overriding the Default Transformations Per Request\n *\n * If you wish to override the request/response transformations only for a single request then provide\n * `transformRequest` and/or `transformResponse` properties on the configuration object passed\n * into `$http`.\n *\n * Note that if you provide these properties on the config object the default transformations will be\n * overwritten. If you wish to augment the default transformations then you must include them in your\n * local transformation array.\n *\n * The following code demonstrates adding a new response transformation to be run after the default response\n * transformations have been run.\n *\n * ```js\n * function appendTransform(defaults, transform) {\n *\n * // We can't guarantee that the default transformation is an array\n * defaults = angular.isArray(defaults) ? defaults : [defaults];\n *\n * // Append the new transformation to the defaults\n * return defaults.concat(transform);\n * }\n *\n * $http({\n * url: '...',\n * method: 'GET',\n * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {\n * return doTransform(value);\n * })\n * });\n * ```\n *\n *\n * ## Caching\n *\n * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must\n * set the config.cache value or the default cache value to TRUE or to a cache object (created\n * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes\n * precedence over the default cache value.\n *\n * In order to:\n * * cache all responses - set the default cache value to TRUE or to a cache object\n * * cache a specific response - set config.cache value to TRUE or to a cache object\n *\n * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,\n * then the default `$cacheFactory(\"$http\")` object is used.\n *\n * The default cache value can be set by updating the\n * {@link ng.$http#defaults `$http.defaults.cache`} property or the\n * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.\n *\n * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using\n * the relevant cache object. The next time the same request is made, the response is returned\n * from the cache without sending a request to the server.\n *\n * Take note that:\n *\n * * Only GET and JSONP requests are cached.\n * * The cache key is the request URL including search parameters; headers are not considered.\n * * Cached responses are returned asynchronously, in the same way as responses from the server.\n * * If multiple identical requests are made using the same cache, which is not yet populated,\n * one request will be made to the server and remaining requests will return the same response.\n * * A cache-control header on the response does not affect if or how responses are cached.\n *\n *\n * ## Interceptors\n *\n * Before you start creating interceptors, be sure to understand the\n * {@link ng.$q $q and deferred/promise APIs}.\n *\n * For purposes of global error handling, authentication, or any kind of synchronous or\n * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n * able to intercept requests before they are handed to the server and\n * responses before they are handed over to the application code that\n * initiated these requests. The interceptors leverage the {@link ng.$q\n * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n *\n * The interceptors are service factories that are registered with the `$httpProvider` by\n * adding them to the `$httpProvider.interceptors` array. The factory is called and\n * injected with dependencies (if specified) and returns the interceptor.\n *\n * There are two kinds of interceptors (and two kinds of rejection interceptors):\n *\n * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to\n * modify the `config` object or create a new one. The function needs to return the `config`\n * object directly, or a promise containing the `config` or a new `config` object.\n * * `requestError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n * * `response`: interceptors get called with http `response` object. The function is free to\n * modify the `response` object or create a new one. The function needs to return the `response`\n * object directly, or as a promise containing the `response` or a new `response` object.\n * * `responseError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n *\n *\n * ```js\n * // register the interceptor as a service\n * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n * return {\n * // optional method\n * 'request': function(config) {\n * // do something on success\n * return config;\n * },\n *\n * // optional method\n * 'requestError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * },\n *\n *\n *\n * // optional method\n * 'response': function(response) {\n * // do something on success\n * return response;\n * },\n *\n * // optional method\n * 'responseError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * }\n * };\n * });\n *\n * $httpProvider.interceptors.push('myHttpInterceptor');\n *\n *\n * // alternatively, register the interceptor via an anonymous factory\n * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n * return {\n * 'request': function(config) {\n * // same as above\n * },\n *\n * 'response': function(response) {\n * // same as above\n * }\n * };\n * });\n * ```\n *\n * ## Security Considerations\n *\n * When designing web applications, consider security threats from:\n *\n * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n *\n * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes\n * pre-configured with strategies that address these issues, but for this to work backend server\n * cooperation is required.\n *\n * ### JSON Vulnerability Protection\n *\n * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * allows third party website to turn your JSON resource URL into\n * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n * AngularJS will automatically strip the prefix before processing it as JSON.\n *\n * For example if your server needs to return:\n * ```js\n * ['one','two']\n * ```\n *\n * which is vulnerable to attack, your server can return:\n * ```js\n * )]}',\n * ['one','two']\n * ```\n *\n * AngularJS will strip the prefix, before processing the JSON.\n *\n *\n * ### Cross Site Request Forgery (XSRF) Protection\n *\n * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by\n * which the attacker can trick an authenticated user into unknowingly executing actions on your\n * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the\n * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP\n * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read\n * the cookie, your server can be assured that the XHR came from JavaScript running on your\n * domain.\n *\n * To take advantage of this, your server needs to set a token in a JavaScript readable session\n * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be\n * sure that only JavaScript running on your domain could have sent the request. The token must\n * be unique for each user and must be verifiable by the server (to prevent the JavaScript from\n * making up its own tokens). We recommend that the token is a digest of your site's\n * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))\n * for added security.\n *\n * The header will — by default — **not** be set for cross-domain requests. This\n * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining\n * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you\n * want to, you can whitelist additional origins to also receive the XSRF token, by adding them\n * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be\n * useful, for example, if your application, served from `example.com`, needs to access your API\n * at `api.example.com`.\n * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for\n * more details.\n *\n *

\n * **Warning**
\n * Only whitelist origins that you have control over and make sure you understand the\n * implications of doing so.\n *

\n *\n * The name of the cookie and the header can be specified using the `xsrfCookieName` and\n * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,\n * `$http.defaults` at run-time, or the per-request config object.\n *\n * In order to prevent collisions in environments where multiple AngularJS apps share the\n * same domain or subdomain, we recommend that each application uses a unique cookie name.\n *\n *\n * @param {object} config Object describing the request to be made and how it should be\n * processed. The object has following properties:\n *\n * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)\n * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;\n * or an object created by a call to `$sce.trustAsResourceUrl(url)`.\n * - **params** – `{Object.}` – Map of strings or objects which will be serialized\n * with the `paramSerializer` and appended as GET parameters.\n * - **data** – `{string|Object}` – Data to be sent as the request message data.\n * - **headers** – `{Object}` – Map of strings or functions which return strings representing\n * HTTP headers to send to the server. If the return value of a function is null, the\n * header will not be sent. Functions accept a config object as an argument.\n * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.\n * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.\n * The handler will be called in the context of a `$apply` block.\n * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload\n * object.

The `expression` is evaluated against each item and the output is used\n * for comparing with other items.\n *\n * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in\n * ascending order.\n *\n * The comparison is done using the `comparator` function. If none is specified, a default, built-in\n * comparator is used (see below for details - in a nutshell, it compares numbers numerically and\n * strings alphabetically).\n *\n * ### Under the hood\n *\n * Ordering the specified `collection` happens in two phases:\n *\n * 1. All items are passed through the predicate (or predicates), and the returned values are saved\n * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed\n * through a predicate that extracts the value of the `label` property, would be transformed to:\n * ```\n * {\n * value: 'foo',\n * type: 'string',\n * index: ...\n * }\n * ```\n * **Note:** `null` values use `'null'` as their type.\n * 2. The comparator function is used to sort the items, based on the derived values, types and\n * indices.\n *\n * If you use a custom comparator, it will be called with pairs of objects of the form\n * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal\n * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the\n * second, or `1` otherwise.\n *\n * In order to ensure that the sorting will be deterministic across platforms, if none of the\n * specified predicates can distinguish between two items, `orderBy` will automatically introduce a\n * dummy predicate that returns the item's index as `value`.\n * (If you are using a custom comparator, make sure it can handle this predicate as well.)\n *\n * If a custom comparator still can't distinguish between two items, then they will be sorted based\n * on their index using the built-in comparator.\n *\n * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted\n * value for an item, `orderBy` will try to convert that object to a primitive value, before passing\n * it to the comparator. The following rules govern the conversion:\n *\n * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be\n * used instead.
\n * (If the object has a `valueOf()` method that returns another object, then the returned object\n * will be used in subsequent steps.)\n * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that\n * returns a primitive, its return value will be used instead.
\n * (If the object has a `toString()` method that returns another object, then the returned object\n * will be used in subsequent steps.)\n * 3. No conversion; the object itself is used.\n *\n * ### The default comparator\n *\n * The default, built-in comparator should be sufficient for most usecases. In short, it compares\n * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to\n * using their index in the original collection, sorts values of different types by type and puts\n * `undefined` and `null` values at the end of the sorted list.\n *\n * More specifically, it follows these steps to determine the relative order of items:\n *\n * 1. If the compared values are of different types:\n * - If one of the values is undefined, consider it \"greater than\" the other.\n * - Else if one of the values is null, consider it \"greater than\" the other.\n * - Else compare the types themselves alphabetically.\n * 2. If both values are of type `string`, compare them alphabetically in a case- and\n * locale-insensitive way.\n * 3. If both values are objects, compare their indices instead.\n * 4. Otherwise, return:\n * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).\n * - `-1`, if the 1st value is \"less than\" the 2nd value (compared using the `<` operator).\n * - `1`, otherwise.\n *\n * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being\n * saved as numbers and not strings.\n * **Note:** For the purpose of sorting, `null` and `undefined` are considered \"greater than\"\n * any other value (with undefined \"greater than\" null). This effectively means that `null`\n * and `undefined` values end up at the end of a list sorted in ascending order.\n * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects.\n *\n * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.\n * @param {(Function|string|Array.)=} expression - A predicate (or list of\n * predicates) to be used by the comparator to determine the order of elements.\n *\n * Can be one of:\n *\n * - `Function`: A getter function. This function will be called with each item as argument and\n * the return value will be used for sorting.\n * - `string`: An AngularJS expression. This expression will be evaluated against each item and the\n * result will be used for sorting. For example, use `'label'` to sort by a property called\n * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`\n * property.
\n * (The result of a constant expression is interpreted as a property name to be used for\n * comparison. For example, use `'\"special name\"'` (note the extra pair of quotes) to sort by a\n * property called `special name`.)
\n * An expression can be optionally prefixed with `+` or `-` to control the sorting direction,\n * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,\n * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.\n * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the\n * relative order of two items, the next predicate is used as a tie-breaker.\n *\n * **Note:** If the predicate is missing or empty then it defaults to `'+'`.\n *\n * @param {boolean=} reverse - If `true`, reverse the sorting order.\n * @param {(Function)=} comparator - The comparator function used to determine the relative order of\n * value pairs. If omitted, the built-in comparator will be used.\n *\n * @returns {Array} - The sorted array.\n *\n *\n * @example\n * ### Ordering a table with `ngRepeat`\n *\n * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by\n * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means\n * it defaults to the built-in comparator.\n *\n \n \n

\n *\n * @example\n * ### Using a custom comparator\n *\n * If you have very specific requirements about the way items are sorted, you can pass your own\n * comparator function. For example, you might need to compare some strings in a locale-sensitive\n * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`\n * argument - passing `false` retains the default sorting order, i.e. ascending.)\n *\n \n \n

This means that the outer form is valid when all of the child\n * forms are valid as well. However, browsers do not allow nesting of `` elements, so\n * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to\n * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group\n * of controls needs to be determined.\n *\n * ## CSS classes\n * - `ng-valid` is set if the form is valid.\n * - `ng-invalid` is set if the form is invalid.\n * - `ng-pending` is set if the form is pending.\n * - `ng-pristine` is set if the form is pristine.\n * - `ng-dirty` is set if the form is dirty.\n * - `ng-submitted` is set if the form was submitted.\n *\n * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n *\n *\n * ## Submitting a form and preventing the default action\n *\n * Since the role of forms in client-side AngularJS applications is different than in classical\n * roundtrip apps, it is desirable for the browser not to translate the form submission into a full\n * page reload that sends the data to the server. Instead some javascript logic should be triggered\n * to handle the form submission in an application-specific way.\n *\n * For this reason, AngularJS prevents the default action (form submission to the server) unless the\n * `` element has an `action` attribute specified.\n *\n * You can use one of the following two ways to specify what javascript method should be called when\n * a form is submitted:\n *\n * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n * - {@link ng.directive:ngClick ngClick} directive on the first\n * button or input field of type submit (input[type=submit])\n *\n * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}\n * or {@link ng.directive:ngClick ngClick} directives.\n * This is because of the following form submission rules in the HTML specification:\n *\n * - If a form has only one input field then hitting enter in this field triggers form submit\n * (`ngSubmit`)\n * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter\n * doesn't trigger submit\n * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n *\n * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is\n * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * @animations\n * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.\n * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any\n * other validations that are performed within the form. Animations in ngForm are similar to how\n * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well\n * as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style a form element\n * that has been rendered as invalid after it has been validated:\n *\n *

\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-form {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-form.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n *

\n * All inputs controlled by {@link ngModel ngModel} (including those of type `radio`) will use the\n * value of their `name` attribute to determine the property under which their\n * {@link ngModel.NgModelController NgModelController} will be published on the parent\n * {@link form.FormController FormController}. Thus, if you use the same `name` for multiple\n * inputs of a form (e.g. a group of radio inputs), only _one_ `NgModelController` will be\n * published on the parent `FormController` under that name. The rest of the controllers will\n * continue to work as expected, but you won't be able to access them as properties on the parent\n * `FormController`.\n *\n *

\n *

\n * In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so\n * that the browser can manage their state (checked/unchecked) based on the state of other\n * inputs in the same group.\n *

\n *

\n * In AngularJS forms, this is not necessary. The input's state will be updated based on the\n * value of the underlying model data.\n *

Model binding,\n * validation and number parsing are nevertheless supported.\n *\n * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`\n * in a way that never allows the input to hold an invalid value. That means:\n * - any non-numerical value is set to `(max + min) / 2`.\n * - any numerical value that is less than the current min val, or greater than the current max val\n * is set to the min / max val respectively.\n * - additionally, the current `step` is respected, so the nearest value that satisfies a step\n * is used.\n *\n * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))\n * for more info.\n *\n * This has the following consequences for AngularJS:\n *\n * Since the element value should always reflect the current model value, a range input\n * will set the bound ngModel expression to the value that the browser has set for the\n * input element. For example, in the following input ``,\n * if the application sets `model.value = null`, the browser will set the input to `'50'`.\n * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.\n *\n * That means the model for range will immediately be set to `50` after `ngModel` has been\n * initialized. It also means a range input can never have the required error.\n *\n * This does not only affect changes to the model value, but also to the values of the `min`,\n * `max`, and `step` attributes. When these change in a way that will cause the browser to modify\n * the input value, AngularJS will also update the model value.\n *\n * Automatic value adjustment also means that a range input element can never have the `required`,\n * `min`, or `max` errors.\n *\n * However, `step` is currently only fully implemented by Firefox. Other browsers have problems\n * when the step value changes dynamically - they do not adjust the element value correctly, but\n * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`\n * error on the input, and set the model to `undefined`.\n *\n * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do\n * not set the `min` and `max` attributes, which means that the browser won't automatically adjust\n * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.\n *\n * @param {string} ngModel Assignable AngularJS expression to data-bind to.\n * @param {string=} name Property name of the form under which the control is published.\n * @param {string=} min Sets the `min` validation to ensure that the value entered is greater\n * than `min`.

If the expression evaluates to a string, the string should be one or more space-delimited class\n * names.\n *\n * 2. If the expression evaluates to an object, then for each key-value pair of the\n * object with a truthy value the corresponding key is used as a class name.\n *\n * 3. If the expression evaluates to an array, each element of the array should either be a string as in\n * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array\n * to give you more control over what CSS classes appear. See the code below for an example of this.\n *\n *\n * The directive won't add duplicate classes if a particular class was already set.\n *\n * When the expression changes, the previously added classes are removed and only then are the\n * new classes added.\n *\n * @knownIssue\n * You should not use {@link guide/interpolation interpolation} in the value of the `class`\n * attribute, when using the `ngClass` directive on the same element.\n * See {@link guide/interpolation#known-issues here} for more info.\n *\n * @animations\n * | Animation                        | Occurs                              |\n * |----------------------------------|-------------------------------------|\n * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |\n * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |\n * | {@link ng.$animate#setClass setClass} | just before classes are added and classes are removed from the element at the same time |\n *\n * ### ngClass and pre-existing CSS3 Transitions/Animations\n   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.\n   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder\n   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure\n   to view the step by step details of {@link $animate#addClass $animate.addClass} and\n   {@link $animate#removeClass $animate.removeClass}.\n *\n * @param {expression} ngClass {@link guide/expression Expression} to eval. The result\n *   of the evaluation can be a string representing space delimited class\n *   names, an array, or a map of class names to boolean values. In the case of a map, the\n *   names of the properties whose values are truthy will be added as css classes to the\n *   element.\n *\n * @example\n * ### Basic\n   <example name=\"ng-class\">\n

This is a key aspect of how angular\n * supports the principles behind the Model-View-Controller design pattern.\n *\n * MVC components in angular:\n *\n * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties\n *   are accessed through bindings.\n * * View — The template (HTML with data bindings) that is rendered into the View.\n * * Controller — The `ngController` directive specifies a Controller class; the class contains business\n *   logic behind the application to decorate the scope with functions and values\n *\n * Note that you can also attach controllers to the DOM by declaring it in a route definition\n * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller\n * again using `ng-controller` in the template itself.  This will cause the controller to be attached\n * and executed twice.\n *\n * @element ANY\n * @scope\n * @priority 500\n * @param {expression} ngController Name of a constructor function registered with the current\n * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}\n * that on the current scope evaluates to a constructor function.\n *\n * The controller instance can be published into a scope property by specifying\n * `ng-controller=\"as propertyName\"`.\n *\n * @example\n * Here is a simple form for editing user contact information. Adding, removing, clearing, and\n * greeting are methods declared on the controller (see source tab). These methods can\n * easily be called from the AngularJS markup. Any changes to the data are automatically reflected\n * in the View without the need for a manual update.\n *\n * Two different declaration styles are included below:\n *\n * * one binds methods and properties directly onto the controller using `this`:\n * `ng-controller=\"SettingsController1 as settings\"`\n * * one injects `$scope` into the controller:\n * `ng-controller=\"SettingsController2\"`\n *\n * The second option is more common in the AngularJS community, and is generally used in boilerplates\n * and in this guide. However, there are advantages to binding properties directly to the controller\n * and avoiding scope.\n *\n * * Using `controller as` makes it obvious which controller you are accessing in the template when\n * multiple controllers apply to an element.\n * * If you are writing your controllers as classes you have easier access to the properties and\n * methods, which will appear on the scope, from inside the controller code.\n * * Since there is always a `.` in the bindings, you don't have to worry about prototypal\n * inheritance masking primitives.\n *\n * This example demonstrates the `controller as` syntax.\n *\n * <example name=\"ngControllerAs\" module=\"controllerAsExample\">\n *   <file name=\"index.html\">\n *    <div id=\"ctrl-as-exmpl\"

@ngdoc directive\n * @name ngCsp\n *\n * @restrict A\n * @element ANY\n * @description\n *\n * AngularJS has some features that can conflict with certain restrictions that are applied when using\n * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.\n *\n * If you intend to implement CSP with these rules then you must tell AngularJS not to use these\n * features.\n *\n * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.\n *\n *\n * The following default rules in CSP affect AngularJS:\n *\n * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute\n * code from strings is forbidden. AngularJS makes use of this in the {@link $parse} service to\n * provide a 30% increase in the speed of evaluating AngularJS expressions. (This CSP rule can be\n * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would\n * weaken the protections offered by CSP.)\n *\n * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.\n * This prevents apps from injecting custom styles directly into the document. AngularJS makes use of\n * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these\n * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`\n * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but\n * it is generally not recommended as it would weaken the protections offered by CSP.)\n *\n * If you do not provide `ngCsp` then AngularJS tries to autodetect if CSP is blocking dynamic code\n * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically\n * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a\n * CSP error to be logged in the console:\n *\n * ```\n * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of\n * script in the following Content Security Policy directive: \"default-src 'self'\". Note that\n * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.\n * ```\n *\n * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`\n * directive on an element of the HTML document that appears before the `<script>` tag that loads\n * the `angular.js` file.\n *\n * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*\n *\n * You can specify which of the CSP related AngularJS features should be deactivated by providing\n * a value for the `ng-csp` attribute. The options are as follows:\n *\n * * no-inline-style: this stops AngularJS from injecting CSS styles into the DOM\n *\n * * no-unsafe-eval: this stops AngularJS from optimizing $parse with unsafe eval of strings\n *\n * You can use these values in the following combinations:\n *\n *\n * * No declaration means that AngularJS will assume that you can do inline styles, but it will do\n * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous\n * versions of AngularJS.\n *\n * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell AngularJS to deactivate both inline\n * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous\n * versions of AngularJS.\n *\n * * Specifying only `no-unsafe-eval` tells AngularJS that we must not use eval, but that we can\n * inject inline styles. E.g. `<body ng-csp=\"no-unsafe-eval\">`.\n *\n * * Specifying only `no-inline-style` tells AngularJS that we must not inject styles, but that we can\n * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp=\"no-inline-style\">`\n *\n * * Specifying both `no-unsafe-eval` and `no-inline-style` tells AngularJS that we must not inject\n * styles nor use eval, which is the same as an empty: ng-csp.\n * E.g.`<body ng-csp=\"no-inline-style;no-unsafe-eval\">`\n *\n * @example\n *\n * This example shows how to apply the `ngCsp` directive to the `html` tag.\n   ```html\n     <!doctype html>\n     <html ng-app ng-csp>\n     ...\n     ...\n     </html>\n   ```\n\n  \n  <example name=\"example.csp\" module=\"cspExample\" ng-csp=\"true\">\n    <file name=\"index.html\">\n      <div ng-controller=\"MainController as ctrl\">\n        <div>\n          <button ng-click=\"ctrl.inc()\" id=\"inc\">Increment</button>\n          <span id=\"counter\">\n            {{ctrl.counter}}\n          </span>\n        </div>\n\n        <div>\n          <button ng-click=\"ctrl.evil()\" id=\"evil\">Evil</button>\n          <span id=\"evilError\">\n            {{ctrl.evilError}}\n          </span>\n        </div>\n      </div>\n    </file>\n    <file name=\"script.js\">\n       angular.module('cspExample', [])\n         .controller('MainController', function MainController() {\n            this.counter = 0;\n            this.inc = function() {\n              this.counter++;\n            };\n            this.evil = function() {\n              try {\n                eval('1+2'); // eslint-disable-line no-eval\n              } catch (e) {\n                this.evilError = e.message;\n              }\n            };\n          });\n    </file>\n    <file name=\"protractor.js\" type=\"protractor\">\n      var util, webdriver;\n\n      var incBtn = element(by.id('inc'));\n      var counter = element(by.id('counter'));\n      var evilBtn = element(by.id('evil'));\n      var evilError = element(by.id('evilError'));\n\n      function getAndClearSevereErrors() {\n        return browser.manage().logs().get('browser').then(function(browserLog) {\n          return browserLog.filter(function(logEntry) {\n            return logEntry.level.value > webdriver.logging.Level.WARNING.value;\n          });\n        });\n      }\n\n      function clearErrors() {\n        getAndClearSevereErrors();\n      }\n\n      function expectNoErrors() {\n        getAndClearSevereErrors().then(function(filteredLog) {\n          expect(filteredLog.length).toEqual(0);\n          if (filteredLog.length) {\n            console.log('browser console errors: ' + util.inspect(filteredLog));\n          }\n        });\n      }\n\n      function expectError(regex) {\n        getAndClearSevereErrors().then(function(filteredLog) {\n          var found = false;\n          filteredLog.forEach(function(log) {\n            if (log.message.match(regex)) {\n              found = true;\n            }\n          });\n          if (!found) {\n            throw new Error('expected an error that matches ' + regex);\n          }\n        });\n      }\n\n      beforeEach(function() {\n        util = require('util');\n        webdriver = require('selenium-webdriver');\n      });\n\n      // For now, we only test on Chrome,\n      // as Safari does not load the page with Protractor's injected scripts,\n      // and Firefox webdriver always disables content security policy (#6358)\n      if (browser.params.browser !== 'chrome') {\n        return;\n      }\n\n      it('should not report errors when the page is loaded', function() {\n        // clear errors so we are not dependent on previous tests\n        clearErrors();\n        // Need to reload the page as the page is already loaded when\n        // we come here\n        browser.driver.getCurrentUrl().then(function(url) {\n          browser.get(url);\n        });\n        expectNoErrors();\n      });\n\n      it('should evaluate expressions', function() {\n        expect(counter.getText()).toEqual('0');\n        incBtn.click();\n        expect(counter.getText()).toEqual('1');\n        expectNoErrors();\n      });\n\n      it('should throw and report an error when using \"eval\"', function() {\n        evilBtn.click();\n        expect(evilError.getText()).toMatch(/Content Security Policy/);\n        expectError(/Content Security Policy/);\n      });\n    </file>\n  </example>\n  */\n\n// `ngCsp` is not implemented as a proper directive any more, because we need it be processed while\n// we bootstrap the app (before `$parse` is instantiated).

If the expression assigned to `ngIf` evaluates to a false\n * value then the element is removed from the DOM, otherwise a clone of the\n * element is reinserted into the DOM.\n *\n * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the\n * element in the DOM rather than changing its visibility via the `display` css property.  A common\n * case when this difference is significant is when using css selectors that rely on an element's\n * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.\n *\n * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope\n * is created when the element is restored.  The scope created within `ngIf` inherits from\n * its parent scope using\n * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).\n * An important implication of this is if `ngModel` is used within `ngIf` to bind to\n * a javascript primitive defined in the parent scope. In this case any modifications made to the\n * variable within the child scope will override (hide) the value in the parent scope.\n *\n * Also, `ngIf` recreates elements using their compiled state. An example of this behavior\n * is if an element's class attribute is directly modified after it's compiled, using something like\n * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element\n * the added class will be lost because the original compiled state is used to regenerate the element.\n *\n * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`\n * and `leave` effects.\n *\n * @animations\n * | Animation                        | Occurs                               |\n * |----------------------------------|-------------------------------------|\n * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |\n * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |\n *\n * @element ANY\n * @scope\n * @priority 600\n * @param {expression} ngIf If the {@link guide/expression expression} is falsy then\n *     the element is removed from the DOM tree.

Both of these inputs are only updated if they are blurred. Hitting escape should\n * empty them. Follow these steps and observe the difference:

\n *

Type something in the input. You will see that the model is not yet updated
Press the Escape key.\n *
1. In the first example, nothing happens, because the model is already '', and no\n * update is detected. If you blur the input, the model will be set to the current view.\n *
2. In the second example, the pending update is cancelled, and the input is set back\n * to the last committed view value (''). Blurring the input does nothing.\n *

If the property doesn't already exist on this scope, it will be created\n * implicitly and added to the scope.\n *\n * For best practices on using `ngModel`, see:\n *\n * - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)\n *\n * For basic examples, how to use `ngModel`, see:\n *\n * - {@link ng.directive:input input}\n * - {@link input[text] text}\n * - {@link input[checkbox] checkbox}\n * - {@link input[radio] radio}\n * - {@link input[number] number}\n * - {@link input[email] email}\n * - {@link input[url] url}\n * - {@link input[date] date}\n * - {@link input[datetime-local] datetime-local}\n * - {@link input[time] time}\n * - {@link input[month] month}\n * - {@link input[week] week}\n * - {@link ng.directive:select select}\n * - {@link ng.directive:textarea textarea}\n *\n * ## Complex Models (objects or collections)\n *\n * By default, `ngModel` watches the model by reference, not value. This is important to know when\n * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the\n * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered.\n *\n * The model must be assigned an entirely new object or collection before a re-rendering will occur.\n *\n * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression\n * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or\n * if the select is given the `multiple` attribute.\n *\n * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the\n * first level of the object (or only changing the properties of an item in the collection if it's an array) will still\n * not trigger a re-rendering of the model.\n *\n * ## CSS classes\n * The following CSS classes are added and removed on the associated input/select/textarea element\n * depending on the validity of the model.\n *\n * - `ng-valid`: the model is valid\n * - `ng-invalid`: the model is invalid\n * - `ng-valid-[key]`: for each valid key added by `$setValidity`\n * - `ng-invalid-[key]`: for each invalid key added by `$setValidity`\n * - `ng-pristine`: the control hasn't been interacted with yet\n * - `ng-dirty`: the control has been interacted with\n * - `ng-touched`: the control has been blurred\n * - `ng-untouched`: the control hasn't been blurred\n * - `ng-pending`: any `$asyncValidators` are unfulfilled\n * - `ng-empty`: the view does not contain a value or the value is deemed \"empty\", as defined\n * by the {@link ngModel.NgModelController#$isEmpty} method\n * - `ng-not-empty`: the view contains a non-empty value\n *\n * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n *\n * @animations\n * Animations within models are triggered when any of the associated CSS classes are added and removed\n * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,\n * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.\n * The animations that are triggered within ngModel are similar to how they work in ngClass and\n * animations can be hooked into using CSS transitions, keyframes as well as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style an input element\n * that has been rendered as invalid after it has been validated:\n *\n *

\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-input {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-input.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n *

\n *\n * @example\n * ### Basic Usage\n * \n \n \n \n

\n Update input to see transitions when valid/invalid.\n Integer is a valid value.\n

\n \n \n * \n *\n * @example\n * ### Binding to a getter/setter\n *\n * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a\n * function that returns a representation of the model when called with zero arguments, and sets\n * the internal state of a model when called with an argument. It's sometimes useful to use this\n * for models that have an internal representation that's different from what the model exposes\n * to the view.\n *\n *

\n * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more\n * frequently than other parts of your code.\n *

\n *\n * You use this behavior by adding `ng-model-options=\"{ getterSetter: true }\"` to an element that\n * has `ng-model` attached to it. You can also add `ng-model-options=\"{ getterSetter: true }\"` to\n * a `

`, which will enable this behavior for all ``s within it. See\n * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.\n *\n * The following example shows how to use `ngModel` with a getter/setter:\n *\n * @example\n * \n \n

You can specify an `ngModelOptions` directive on any element. All {@link ngModel}\n * directives will use the options of their nearest `ngModelOptions` ancestor.\n *\n * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as\n * an AngularJS expression. This expression should evaluate to an object, whose properties contain\n * the settings. For example: `

\n * \n *

\n * ```\n *\n * the `input` element will have the following settings\n *\n * ```js\n * { allowInvalid: true, updateOn: 'default', debounce: 0 }\n * ```\n *\n * Notice that the `debounce` setting was not inherited and used the default value instead.\n *\n * You can specify that all undefined settings are automatically inherited from an ancestor by\n * including a property with key of `\"*\"` and value of `\"$inherit\"`.\n *\n * For example given the following fragment of HTML\n *\n *\n * ```html\n *

\n * \n *

\n * ```\n *\n * the `input` element will have the following settings\n *\n * ```js\n * { allowInvalid: true, updateOn: 'default', debounce: 200 }\n * ```\n *\n * Notice that the `debounce` setting now inherits the value from the outer `

` element.\n *\n * If you are creating a reusable component then you should be careful when using `\"*\": \"$inherit\"`\n * since you may inadvertently inherit a setting in the future that changes the behavior of your component.\n *\n *\n * ## Triggering and debouncing model updates\n *\n * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will\n * trigger a model update and/or a debouncing delay so that the actual update only takes place when\n * a timer expires; this timer will be reset after another change takes place.\n *\n * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might\n * be different from the value in the actual model. This means that if you update the model you\n * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in\n * order to make sure it is synchronized with the model and that any debounced action is canceled.\n *\n * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}\n * method is by making sure the input is placed inside a form that has a `name` attribute. This is\n * important because `form` controllers are published to the related scope under the name in their\n * `name` attribute.\n *\n * Any pending changes will take place immediately when an enclosing form is submitted via the\n * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * ### Overriding immediate updates\n *\n * The following example shows how to override immediate updates. Changes on the inputs within the\n * form will update the model only when the control loses focus (blur event). If `escape` key is\n * pressed while the input field is focused, the value is reset to the value in the current model.\n *\n * \n * \n *

Model will be updated only 1 sec after last change.\n * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.\n *\n * \n * \n *

\n * \n * \n * angular.module('optionsExample', [])\n * .controller('ExampleController', ['$scope', function($scope) {\n * $scope.user = { name: 'say' };\n * }]);\n * \n * \n *\n * ### Default events, extra triggers, and catch-all debounce values\n *\n * This example shows the relationship between \"default\" update events and\n * additional `updateOn` triggers.\n *\n * `default` events are those that are bound to the control, and when fired, update the `$viewValue`\n * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed\n * in `updateOn` is considered a \"default\" event, since different control types have different\n * default events.\n *\n * The control in this example updates by \"default\", \"click\", and \"blur\", with different `debounce`\n * values. You can see that \"click\" doesn't have an individual `debounce` value -\n * therefore it uses the `*` debounce value.\n *\n * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}\n * directly with a \"custom\" event. Since \"custom\" is not defined in the `updateOn` list,\n * it is considered a \"default\" event and will update the\n * control if \"default\" is defined in `updateOn`, and will receive the \"default\" debounce value.\n * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.\n *\n * You can change the `updateOn` and `debounce` configuration to test different scenarios. This\n * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.\n *\n \n \n \n \n \n angular.module('optionsExample', [])\n .component('modelUpdateDemo', {\n templateUrl: 'template.html',\n controller: function() {\n this.name = 'Chinua';\n\n this.options = {\n updateOn: 'default blur click',\n debounce: {\n default: 2000,\n blur: 0,\n '*': 1000\n }\n };\n\n this.updateEvents = function() {\n var eventList = this.options.updateOn.split(' ');\n eventList.push('*');\n var events = {};\n\n for (var i = 0; i < eventList.length; i++) {\n events[eventList[i]] = this.options.debounce[eventList[i]];\n }\n\n this.events = events;\n };\n\n this.updateOptions = function() {\n var options = angular.extend(this.options, {\n updateOn: Object.keys(this.events).join(' ').replace('*', ''),\n debounce: this.events\n });\n\n this.form.input.$overrideModelOptions(options);\n };\n\n // Initialize the event form\n this.updateEvents();\n }\n });\n \n \n \n Model: {{$ctrl.name}}\n

\n \n \n *\n *\n * ## Model updates and validation\n *\n * The default behaviour in `ngModel` is that the model value is set to `undefined` when the\n * validation determines that the value is invalid. By setting the `allowInvalid` property to true,\n * the model will still be updated even if the value is invalid.\n *\n *\n * ## Connecting to the scope\n *\n * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression\n * on the scope refers to a \"getter/setter\" function rather than the value itself.\n *\n * The following example shows how to bind to getter/setters:\n *\n * \n * \n *

\n * \n *

user.name =

\n *

\n * \n * \n * angular.module('getterSetterExample', [])\n * .controller('ExampleController', ['$scope', function($scope) {\n * var _name = 'Brian';\n * $scope.user = {\n * name: function(newName) {\n * return angular.isDefined(newName) ? (_name = newName) : _name;\n * }\n * };\n * }]);\n * \n * \n *\n *\n * ## Programmatically changing options\n *\n * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not\n * watched for changes. However, it is possible to override the options on a single\n * {@link ngModel.NgModelController} instance with\n * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.\n * See also the example for\n * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values\n * Default events, extra triggers, and catch-all debounce values}.\n *\n *\n * ## Specifying timezones\n *\n * You can specify the timezone that date/time input directives expect by providing its name in the\n * `timezone` property.\n *\n *\n * ## Formatting the value of `time` and `datetime-local`\n *\n * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value\n * that is displayed in the control. Note that browsers may apply their own formatting\n * in the user interface.\n *\n \n \n \n \n \n angular.module('timeExample', [])\n .component('timeExample', {\n templateUrl: 'timeExample.html',\n controller: function() {\n this.time = new Date(1970, 0, 1, 14, 57, 0);\n\n this.options = {\n timeSecondsFormat: 'ss',\n timeStripZeroSeconds: true\n };\n\n this.optionChange = function() {\n this.timeForm.timeFormatted.$overrideModelOptions(this.options);\n this.time = new Date(this.time);\n };\n }\n });\n \n \n

\n timeSecondsFormat:\n \n
\n timeStripZeroSeconds:\n \n \n

\n * \n *\n * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and\n * and its descendents.\n *\n * **General options**:\n *\n * - `updateOn`: string specifying which event should the input be bound to. You can set several\n * events using an space delimited list. There is a special event called `default` that\n * matches the default events belonging to the control. These are the events that are bound to\n * the control, and when fired, update the `$viewValue` via `$setViewValue`.\n *\n * `ngModelOptions` considers every event that is not listed in `updateOn` a \"default\" event,\n * since different control types use different default events.\n *\n * See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates\n * Triggering and debouncing model updates}.\n *\n * - `debounce`: integer value which contains the debounce model update value in milliseconds. A\n * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a\n * custom value for each event. For example:\n * ```\n * ng-model-options=\"{\n * updateOn: 'default blur',\n * debounce: { 'default': 500, 'blur': 0 }\n * }\"\n * ```\n * You can use the `*` key to specify a debounce value that applies to all events that are not\n * specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:\n * ```\n * ng-model-options=\"{\n * updateOn: 'default blur mouseup',\n * debounce: { 'default': 500, 'blur': 0, '*': 1000 }\n * }\"\n * ```\n * - `allowInvalid`: boolean value which indicates that the model can be set with values that did\n * not validate correctly instead of the default behavior of setting the model to undefined.\n * - `getterSetter`: boolean value which determines whether or not to treat functions bound to\n * `ngModel` as getters/setters.\n *\n *\n * **Input-type specific options**:\n *\n * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for\n * ``, ``, ... . It understands UTC/GMT and the\n * continental US time zone abbreviations, but for general use, use a time zone offset, for\n * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)\n * If not specified, the timezone of the browser will be used.\n * Note that changing the timezone will have no effect on the current date, and is only applied after\n * the next input / model change.\n *\n * - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and\n * milliseconds. The option follows the format string of {@link date date filter}.\n * By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).\n * The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both\n * seconds and milliseconds.\n * Note that browsers that support `time` and `datetime-local` require the hour and minutes\n * part of the time string, and may show the value differently in the user interface.\n * {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.\n *\n * - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the\n * seconds and milliseconds from the formatted value if they are zero. This option is applied\n * after `timeSecondsFormat`.\n * This option can be used to make the formatting consistent over different browsers, as some\n * browsers with support for `time` will natively hide the milliseconds and\n * seconds if they are zero, but others won't, and browsers that don't implement these input\n * types will always show the full string.\n * {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.\n *\n */\nvar ngModelOptionsDirective = function() {\n NgModelOptionsController.$inject = ['$attrs', '$scope'];\n function NgModelOptionsController($attrs, $scope) {\n this.$$attrs = $attrs;\n this.$$scope = $scope;\n }\n NgModelOptionsController.prototype = {\n $onInit: function() {\n var parentOptions = this.parentCtrl ? this.parentCtrl.$options : defaultModelOptions;\n var modelOptionsDefinition = this.$$scope.$eval(this.$$attrs.ngModelOptions);\n\n this.$options = parentOptions.createChild(modelOptionsDefinition);\n }\n };\n\n return {\n restrict: 'A',\n // ngModelOptions needs to run before ngModel and input directives\n priority: 10,\n require: {parentCtrl: '?^^ngModelOptions'},\n bindToController: true,\n controller: NgModelOptionsController\n };\n};\n\n\n// shallow copy over values from `src` that are not already specified on `dst`\nfunction defaults(dst, src) {\n forEach(src, function(value, key) {\n if (!isDefined(dst[key])) {\n dst[key] = value;\n }\n });\n}\n\n/**\n * @ngdoc directive\n * @name ngNonBindable\n * @restrict AC\n * @priority 1000\n * @element ANY\n *\n * @description\n * The `ngNonBindable` directive tells AngularJS not to compile or bind the contents of the current\n * DOM element, including directives on the element itself that have a lower priority than\n * `ngNonBindable`.
