我是AngularJS的新手。我必须为视频播放器创建海关控制(HTML5 <video>
)。
基本上,我会使用getElementById('myvideotag')
,聆听视频点击播放/暂停。
我如何使用AngularJS做到这一点?将点击与ng-click="videoPlayPause()"
绑定,但之后,我如何播放或暂停视频。我如何使用<video>
的经典方法?
我想这很简单......我还没有得到所有的AngularJS概念!
谢谢:)
哦,代码......在视图中:
<video autoplay="autoplay" preload="auto" ng-click="video()">
<source src="{{ current.url }}" type="video/mp4" />
</video>
在正确的控制器中:
$scope.video = function() {
this.pause(); // ???
}

对于完全控制,如行为和外观和感觉,我在角度中使用videoJS
。
我有一个ui-video
指令包装video
HTML5元素。这对于克服与AngularJS集成的问题是必要的:
m.directive('uiVideo', function () {
var vp; // video player object to overcome one of the angularjs issues in #1352 (https://github.com/angular/angular.js/issues/1352). when the videojs player is removed from the dom, the player object is not destroyed and can't be reused.
var videoId = Math.floor((Math.random() * 1000) + 100); // in random we trust. you can use a hash of the video uri
return {
template: '<div class="video">' +
'<video ng-src="{{ properties.src }}" id="video-' + videoId + '" class="video-js vjs-default-skin" controls preload="auto" >' +
//'<source type="video/mp4"> '+ /* seems not yet supported in angular */
'Your browser does not support the video tag. ' +
'</video></div>',
link: function (scope, element, attrs) {
scope.properties = 'whatever url';
if (vp) vp.dispose();
vp = videojs('video-' + videoId, {width: 640, height: 480 });
}
};
});

这个怎么样:
在您的HTML中,设置ng-click="video($event)"
(不要忘记$event
参数),它会调用以下函数:
$scope.video = function(e) {
var videoElements = angular.element(e.srcElement);
videoElements[0].pause();
}
我相信这是最简单的方法。

此外,这可能有助于您习惯Angular:How do I “think in AngularJS/EmberJS(or other client MVC framework)” if I have a jQuery background?

您还可以查看我的项目Videogular。
https://github.com/2fdevs/videogular
这是一个用AngularJS编写的视频播放器,因此您将拥有绑定和范围变量的所有好处。你也可以编写自己的主题和插件。

我还使用了videojs
bower install videojs --save
我想在ng-repeat
和范围对象中使用我的指令,所以......这是我的版本,上面有Eduard的道具。我似乎没有处理视频播放器的问题,但source tag issue referenced是一个实际问题。
我还决定把它写成答案,这样我就可以举例说明一个人如何处理videojs事件。
重要!请注意我将Angular.js与Jinja2模板一起使用,因此如果有人注意到,我必须将我的Angular HTML插值标记从{[ ]}
更改为{{ }}
这很奇怪。我也会包含那些代码,所以对任何人来说都不奇怪。
插值调整
app.config(['$interpolateProvider', function($interpolateProvider) {
$interpolateProvider.startSymbol('{[');
$interpolateProvider.endSymbol(']}');
}]);
