`$mdDialog` opens a dialog over the app to inform users about critical information or require * them to make decisions. There are two approaches for setup: a simple promise API * and regular object syntax. * * ## Restrictions * * - The dialog is always given an isolate scope. * - The dialog's template must have an outer `<md-dialog>` element. * Inside, use an `<md-dialog-content>` element for the dialog's content, and use * an `<md-dialog-actions>` element for the dialog's actions. * - Dialogs must cover the entire application to keep interactions inside of them. * Use the `parent` option to change where dialogs are appended. * * ## Sizing * - Complex dialogs can be sized with `flex="percentage"`, i.e. `flex="66"`. * - Default max-width is 80% of the `rootElement` or `parent`. * * ## CSS * - `.md-dialog-content` - class that sets the padding on the content as the spec file * * @usage * <hljs lang="html"> * <div ng-app="demoApp" ng-controller="EmployeeController"> * <div> * <md-button ng-click="showAlert()" class="md-raised md-warn"> * Employee Alert! * </md-button> * </div> * <div> * <md-button ng-click="showDialog($event)" class="md-raised"> * Custom Dialog * </md-button> * </div> * <div> * <md-button ng-click="closeAlert()" ng-disabled="!hasAlert()" class="md-raised"> * Close Alert * </md-button> * </div> * <div> * <md-button ng-click="showGreeting($event)" class="md-raised md-primary" > * Greet Employee * </md-button> * </div> * </div> * </hljs> * * ### JavaScript: object syntax * <hljs lang="js"> * (function(angular, undefined){ * "use strict";

This **must** be trusted HTML * with respect to Angular's [$sce service](https://docs.angularjs.org/api/ng/service/$sce). * This template should **never** be constructed with any kind of user input or user data. * - `contentElement` - `{string|Element}`: Instead of using a template, which will be compiled each time a * dialog opens, you can also use a DOM element.<br/> * * When specifying an element, which is present on the DOM, `$mdDialog` will temporary fetch the element into * the dialog and restores it at the old DOM position upon close. * * When specifying a string, the string be used as a CSS selector, to lookup for the element in the DOM. * - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template with a * `<md-dialog>` tag if one is not provided. Defaults to true. Can be disabled if you provide a * custom dialog directive. * - `targetEvent` - `{DOMClickEvent=}`: A click's event object. When passed in as an option, * the location of the click will be used as the starting point for the opening animation * of the the dialog. * - `openFrom` - `{string|Element|object}`: The query selector, DOM element or the Rect object * that is used to determine the bounds (top, left, height, width) from which the Dialog will * originate. * - `closeTo` - `{string|Element|object}`: The query selector, DOM element or the Rect object * that is used to determine the bounds (top, left, height, width) to which the Dialog will * target. * - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified, * it will create a new isolate scope. * This scope will be destroyed when the dialog is removed unless `preserveScope` is set to true. * - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false * - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the dialog is open. * Default true. * - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop behind the dialog. * Default true. * - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the dialog to * close it. Default false. * - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the dialog. * Default true. * - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on open. Only disable if * focusing some other way, as focus management is required for dialogs to be accessible. * Defaults to true. * - `controller` - `{function|string=}`: The controller to associate with the dialog. The controller * will be injected with the local `$mdDialog`, which passes along a scope for the dialog. * - `locals` - `{object=}`: An object containing key/value pairs. The keys will be used as names * of values to inject into the controller. For example, `locals: {three: 3}` would inject * `three` into the controller, with the value 3. If `bindToController` is true, they will be * copied to the controller instead. * - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in. * - `resolve` - `{object=}`: Similar to locals, except it takes promises as values, and the * dialog will not open until all of the promises resolve. * - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope. * - `parent` - `{element=}`: The element to append the dialog to. Defaults to appending * to the root element of the application. * - `onShowing` - `function(scope, element)`: Callback function used to announce the show() action is * starting. * - `onComplete` - `function(scope, element)`: Callback function used to announce when the show() action is * finished. * - `onRemoving` - `function(element, removePromise)`: Callback function used to announce the * close/hide() action is starting. This allows developers to run custom animations * in parallel the close animations. * - `fullscreen` `{boolean=}`: An option to toggle whether the dialog should show in fullscreen * or not. Defaults to `false`. * - `multiple` `{boolean=}`: An option to allow this dialog to display over one that's currently open. * @returns {promise} A promise that can be resolved with `$mdDialog.hide()` or * rejected with `$mdDialog.cancel()`. */ /** * @ngdoc method * @name $mdDialog#hide * * @description * Hide an existing dialog and resolve the promise returned from `$mdDialog.show()`. * * @param {*=} response An argument for the resolved promise. * * @returns {promise} A promise that is resolved when the dialog has been closed. */ /** * @ngdoc method * @name $mdDialog#cancel * * @description * Hide an existing dialog and reject the promise returned from `$mdDialog.show()`. * * @param {*=} response An argument for the rejected promise. * * @returns {promise} A promise that is resolved when the dialog has been closed. */ function MdDialogProvider($$interimElementProvider) { // Elements to capture and redirect focus when the user presses tab at the dialog boundary. advancedDialogOptions['$inject'] = ["$mdDialog", "$mdConstant"]; dialogDefaultOptions['$inject'] = ["$mdDialog", "$mdAria", "$mdUtil", "$mdConstant", "$animate", "$document", "$window", "$rootElement", "$log", "$injector", "$mdTheming", "$interpolate", "$mdInteraction"]; var topFocusTrap, bottomFocusTrap; return $$interimElementProvider('$mdDialog') .setDefaults({ methods: ['disableParentScroll', 'hasBackdrop', 'clickOutsideToClose', 'escapeToClose', 'targetEvent', 'closeTo', 'openFrom', 'parent', 'fullscreen', 'multiple'], options: dialogDefaultOptions }) .addPreset('alert', { methods: ['title', 'htmlContent', 'textContent', 'content', 'ariaLabel', 'ok', 'theme', 'css'], options: advancedDialogOptions }) .addPreset('confirm', { methods: ['title', 'htmlContent', 'textContent', 'content', 'ariaLabel', 'ok', 'cancel', 'theme', 'css'], options: advancedDialogOptions }) .addPreset('prompt', { methods: ['title', 'htmlContent', 'textContent', 'initialValue', 'content', 'placeholder', 'ariaLabel', 'ok', 'cancel', 'theme', 'css'], options: advancedDialogOptions }); /* ngInject */ function advancedDialogOptions($mdDialog, $mdConstant) { return { template: [ '<md-dialog md-theme="{{ dialog.theme || dialog.defaultTheme }}" aria-label="{{ dialog.ariaLabel }}" ng-class="dialog.css">', ' <md-dialog-content class="md-dialog-content" role="document" tabIndex="-1">', ' <h2 class="md-title">{{ dialog.title }}</h2>', ' <div ng-if="::dialog.mdHtmlContent" class="md-dialog-content-body" ', ' ng-bind-html="::dialog.mdHtmlContent"></div>', ' <div ng-if="::!dialog.mdHtmlContent" class="md-dialog-content-body">', ' <p>{{::dialog.mdTextContent}}</p>', ' </div>', ' <md-input-container md-no-float ng-if="::dialog.$type == \'prompt\'" class="md-prompt-input-container">', ' <input ng-keypress="dialog.keypress($event)" md-autofocus ng-model="dialog.result" ' + ' placeholder="{{::dialog.placeholder}}">', ' </md-input-container>', ' </md-dialog-content>', ' <md-dialog-actions>', ' <md-button ng-if="dialog.$type === \'confirm\' || dialog.$type === \'prompt\'"' + ' ng-click="dialog.abort()" class="md-primary md-cancel-button">', ' {{ dialog.cancel }}', ' </md-button>', ' <md-button ng-click="dialog.hide()" class="md-primary md-confirm-button" md-autofocus="dialog.$type===\'alert\'">', ' {{ dialog.ok }}', ' </md-button>', ' </md-dialog-actions>', '</md-dialog>' ].join('').replace(/\s\s+/g, ''), controller: function mdDialogCtrl() { var isPrompt = this.$type == 'prompt'; if (isPrompt && this.initialValue) { this.result = this.initialValue; } this.hide = function() { $mdDialog.hide(isPrompt ? this.result : true); }; this.abort = function() { $mdDialog.cancel(); }; this.keypress = function($event) { if ($event.keyCode === $mdConstant.KEY_CODE.ENTER) { $mdDialog.hide(this.result); } }; }, controllerAs: 'dialog', bindToController: true, }; } /* ngInject */ function dialogDefaultOptions($mdDialog, $mdAria, $mdUtil, $mdConstant, $animate, $document, $window, $rootElement, $log, $injector, $mdTheming, $interpolate, $mdInteraction) { return { hasBackdrop: true, isolateScope: true, onCompiling: beforeCompile, onShow: onShow, onShowing: beforeShow, onRemove: onRemove, clickOutsideToClose: false, escapeToClose: true, targetEvent: null, closeTo: null, openFrom: null, focusOnOpen: true, disableParentScroll: true, autoWrap: true, fullscreen: false, transformTemplate: function(template, options) { // Make the dialog container focusable, because otherwise the focus will be always redirected to // an element outside of the container, and the focus trap won't work probably.. // Also the tabindex is needed for the `escapeToClose` functionality, because // the keyDown event can't be triggered when the focus is outside of the container. var startSymbol = $interpolate.startSymbol(); var endSymbol = $interpolate.endSymbol(); var theme = startSymbol + (options.themeWatch ?
