To run multiple applications in an HTML document you must manually bootstrap them using\n * {@link angular.bootstrap} instead.\n * - AngularJS applications cannot be nested within each other.\n * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.\n * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and\n * {@link ngRoute.ngView `ngView`}.\n * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},\n * causing animations to stop working and making the injector inaccessible from outside the app.\n *\n * You can specify an **AngularJS module** to be used as the root module for the application. This\n * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It\n * should contain the application code needed or have dependencies on other modules that will\n * contain the code. See {@link angular.module} for more information.\n *\n * In the example below if the `ngApp` directive were not placed on the `html` element then the\n * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`\n * would not be resolved to `3`.\n *\n * `ngApp` is the easiest, and most common way to bootstrap an application.\n *\n \n \n

@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 Angular'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 * Angular 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 Angular 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 * ## Angular's jqLite\n * jqLite provides only the following jQuery methods:\n *\n * - [`addClass()`](http://api.jquery.com/addClass/)\n * - [`after()`](http://api.jquery.com/after/)\n * - [`append()`](http://api.jquery.com/append/)\n * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n * - [`bind()`](http://api.jquery.com/bind/) - 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/)\n * - [`remove()`](http://api.jquery.com/remove/)\n * - [`removeAttr()`](http://api.jquery.com/removeAttr/)\n * - [`removeClass()`](http://api.jquery.com/removeClass/)\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/) - 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 * ## jQuery/jqLite Extras\n * Angular 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 addEventListenerFn = function(element, type, fn) {\n element.addEventListener(type, fn, false);\n },\n removeEventListenerFn = function(element, type, fn) {\n element.removeEventListener(type, fn, false);\n };\n\n/*\n * !!!

\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 \"Directive Definition Object\" (see below) that defines the directive properties,\n * or just the `postLink` function (all other properties will have the default values).\n *\n *
\n * **Best Practice:** It's recommended to use the \"directive definition object\" form.\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 *\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, 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 `true`, an object or a falsy value:\n *\n * * **falsy:** No scope will be created for the directive. The directive will use its 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. The new scope rule does not apply for the root of the template\n * since the root of the template always gets a new scope.\n *\n * * **`{...}` (an object hash):** A new \"isolate\" scope is created for the directive's element. The\n * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent\n * scope. This is useful when creating reusable components, which should not accidentally read or modify\n * data in the parent scope.\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. Optional attributes should be marked as such with a question mark:\n * `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't\n * optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})\n * will be thrown upon discovering changes to the local value, since it will be impossible to sync\n * them back to the parent scope. By default, the {@link ng.$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` (`=*?` or `=*?attr` if the attribute is optional).\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 * 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. Additionally, a controller\n * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller\n * definition: `controller: 'myCtrl as myAlias'`.\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 *
\n * **Deprecation warning:** although bindings for non-ES6 class controllers are currently\n * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization\n * code that relies upon bindings inside a `$onInit` method on the controller, instead.\n *
\n *\n * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.\n * This will set up the scope bindings to the controller directly. Note that `scope` can still be used\n * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate\n * scope (useful for component directives).\n *\n * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.\n *\n *\n * #### `controller`\n * Controller constructor function. The controller is instantiated before the\n * pre-linking phase and can be accessed by other directives (see\n * `require` attribute). This allows the directives to communicate with each other and augment\n * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n *\n * * `$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 `cloneLinkinFn` 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 `
