当 html5 视频结束时调用 AngularJS 控制器函数 [英] Calling AngularJS controller function when html5 video ends

问题描述

我的应用主页上有一个视频，当我启动它时会播放.当视频结束时，我想使用一些 CSS 3 过渡来移动页面.

<离子窗格><div class="home-video"><video autoplay="autoplay" ng-click="ctrl.video()" aria-label="IBM logo 视频" tabindex="-1" aria-hidden="true" poster="images/Hero_Final_Placeholder.gif" onended="ctrl.video()"><source src="videos/video.mp4" type="video/mp4"><img src="images/video_backup.gif" title="您的浏览器不支持视频标签."></视频>

</ion-pane></ion-view>

在视频的最后，我希望能够调用 angularJS 控制器函数.

'use strict';angular.module('app', ['ionic']).config(function ($stateProvider, $urlRouterProvider) {$stateProvider.state('home', {网址:/家"，templateUrl: 'views/home.html',控制器:'homeCtrl 作为 ctrl'}).state('项目', {url: "/project/:projectId",templateUrl: 'views/project.html',控制器:'projectCtrl'});//要显示的默认视图$urlRouterProvider.when('', '/home');}).run(function ($http, pouchDB, replicationService, $rootScope) {replicationService.replicate();});

我的控制器看起来像:

'use strict';var app = angular.module('app', false);app.controller('homeCtrl', function ($rootScope){this.data = {};var ctrl = 这个；this.video = 函数 () {console.log("视频完成");}});

如果我将 console.log() 放在 <video onended=""> 元素中，它会打印出来.如果我尝试调用包含相同 console.log 的 ctrl.video() ，我会收到以下错误:

Uncaught ReferenceError: ctrl is not defined

我知道 ctrl 是定义的，因为如果我添加一个 ng-click="ctrl.video()" 并单击它打印出来的视频播放器.

解决方案

最终我所做的是使用 Angular UI Utils，它有一个通用的事件绑定器.这允许我绑定到一个 AngularJS 没有开箱即用的事件.使用以下行 ui-event="{ end : 'ctrl.video()'}" 我能够在视频结束时调用我的函数，这给了我想要的行为.

I have a video on the homepage of my app which plays when I launch it. When the video ends I'd then like to use some CSS 3 transitions to move the page around.

<ion-view  hide-back-button="true" title="">
    <ion-pane>
        <div class="home-video">
            <video autoplay="autoplay" ng-click="ctrl.video()" aria-label="video of IBM logo" tabindex="-1" aria-hidden="true" poster="images/Hero_Final_Placeholder.gif" onended="ctrl.video()">
                <source src="videos/video.mp4" type="video/mp4">
                <img src="images/video_backup.gif" title="Your browser does not support the video tag.">
            </video>
        </div>
    </ion-pane>
</ion-view>

At the end of the video I'd like to be able to call an angularJS Controller function.

'use strict';

angular.module('app', ['ionic']).config(function ($stateProvider, $urlRouterProvider) {

$stateProvider.state('home', {
  url: "/home",
  templateUrl: 'views/home.html',
  controller: 'homeCtrl as ctrl'
}).state('project', {
  url: "/project/:projectId",
  templateUrl: 'views/project.html',
  controller: 'projectCtrl'
});

 // Default view to show
$urlRouterProvider.when('', '/home');

}).run(function ($http, pouchDB, replicationService, $rootScope) {

  replicationService.replicate();

});

My controller looks like:

'use strict';

var app = angular.module('app', false);

app.controller('homeCtrl', function ($rootScope){

this.data = {};

var ctrl = this;

    this.video = function () {

        console.log("video done");

    }

});

If I put a console.log() in the <video onended=""> element it prints it out. If I try and call ctrl.video() which contains the same console.log I get the following error:

Uncaught ReferenceError: ctrl is not defined

I know that ctrl is defined because if I add an ng-click="ctrl.video()" and I click the video player it prints out.

解决方案

Eventually what I did was use Angular UI Utils which has a generic event binder. This allowed me to bind to an event that AngularJS doesn't out of the box. Using the following line ui-event="{ ended : 'ctrl.video()'}" I was able to call my function when the video ended which gave me the desired behaviour.
