我想要在达到X秒后暂停一段视频。
我可以通过以下方式收听当前时间:
<videogular data-vg-update-time="someFunction($currentTime,$duration)" ...>
</videogular>
我可以抓住我在控制器中寻找的时间:
var controllers = {};
controllers.SomeController = function($scope){
$scope.someFunction($currentTime, $duration){
// this is a total hack method to catch current time
// stay in school or you'll write code like this
if(Math.round($currentTime) === 6){
// RIGHT HERE. I know the API must be exposing the video obj
// but I haven't been able to figure out how to catch it.
//
// var foo = document.getElementsByTagName('video');
// foo.pause();
}
}
}
myApp.controller(controllers);
现在,显然有更好的方法来解决这个问题。我贬低角度以评估currentTime,并尝试识别视频对象,这很难闻。在某种程度上,我很挣扎,因为对象是通过烘焙到Videogular中的指令创建的。我的控制器+部分看起来像:
[continued from above...]
[i.e controllers.SomeController = function($sce, $scope){
// this is the angular controller
$scope.attractConfig = {
sources: [
{src: $sce.trustAsResourceUrl("/video/myVideo.mp4"), type: "video/mp4"}
],
theme: "/bower_components/videogular-themes-default/videogular.css",
plugins: {
poster: "http://www.videogular.com/assets/images/videogular.png"
},
autoPlay: true
};
// and this is the HTML partial
<div data-ng-controller="SomeController as controller">
<videogular data-vg-theme="attractConfig.theme"
data-vg-auto-play="attractConfig.autoPlay"
data-vg-update-time="checkAttractTime($currentTime,$duration)"
data-vg-complete="restartAttract()">
<vg-media data-vg-src="attractConfig.sources"></vg-media>
</videogular>
</div>
我在90%的路上就像我一样,但是我无法弄清楚当currentTime达到X秒时如何直接调用pause()或play()。我无法弄清楚如何定位视频对象,这是通过指令显示的。

我无法让你的例子工作,但通过这个小小的修改,它运行正常(我改变了控制器的创建方式):
var myArray= {};
myArray.MainCtrl = function($scope, $state, $sce) {
$scope.API = null;
$scope.onPlayerReady = function ($API) {
$scope.$API = $API;
};
$scope.checkTime = function($currentTime){
var currentTime = Math.round($currentTime);
if (currentTime >= 10){
$scope.$API.play(); // or whatever $API you want here
}
};
}
app.controller(myArray);
与
<div data-ng-controller="MainCtrl">
<videogular
data-vg-player-ready="onPlayerReady($API)"
data-vg-update-time="checkTime($currentTime)">
<vg-media data-vg-src="config.sources"></vg-media>
</videogular>
</div>
我想知道为什么这会绕过上一个错误?

我建议您抓住Videogular提供的API并使用API上的方法而不是原生视频方法。
在您的HTML中:
<div vg-player-ready="onPlayerReady($API)" data-ng-controller="SomeController as controller">
<videogular data-vg-theme="attractConfig.theme"
data-vg-auto-play="attractConfig.autoPlay"
data-vg-update-time="checkAttractTime($currentTime,$duration)"
data-vg-complete="restartAttract()">
<vg-media data-vg-src="attractConfig.sources"></vg-media>
</videogular>
</div>
然后在你的控制器中:
$scope.onPlayerReady = function($API) {
$scope.$API = $API;
}
$scope.someFunction($currentTime, $duration){
// this is a total hack method to catch current time
// stay in school or you'll write code like this
if(Math.round($currentTime) === 6){
$API.pause();
}
}
您有一个关于在这里使用Videogular API的好教程: http://www.videogular.com/tutorials/videogular-api/
如果你需要获取原生视频元素,你可以通过API获取它:
console.log($scope.$API.mediaElement[0]);
