在元素的背景上随机播放youtube视频

Question

目前，我正在使用这个jquery，它获取youtube视频并在元素的背景中播放它们。

我得到了这个代码，它将播放youtube上的单个视频。但我想做一个视频列表然后随机播放..。我现在对Javascript不太在行，所以我很想在这方面提供一些帮助.

现在我有这个..。

我想制作一张视频列表，像一张杂乱的播放列表一样随机播放。

$(function() 
{ 
    var videos = ['xJvt2SDV7ck', 'x6DD1k4BAUg', 'xJvt2SDV7ck'];
    var index = Math.floor(Math.random() * videos.length);

    var Video_back = new video_background($("#bgvideo"), 
    {
        "position": "absolute", //Stick within the div
        "z-index": "-1",        //Behind everything
        "loop": true,           //Loop when it reaches the end
        "autoplay": true,       //Autoplay at start
        "muted": true,          //Muted at start
        "youtube": "videos[index]",   //Youtube video id
        "start": 0,                 //Start with 6 seconds offset (to pass the introduction in this case for example)
        "video_ratio": 1.333,      // width/height -> If none provided sizing of the video is set to adjust
        "fallback_image": "videos/main.jpg",    //Fallback image path
    });
});

目前它只播放从列表中随机选择的1段视频(单圈)。我想制作它，这样当第一个视频结束时，它就会转到另一个视频。

我们会非常感谢你的帮助！谢谢您抽时间见我!

以下的答案是基于这样的事实，即没有办法确定什么时候视频已经完成。长度以毫秒为单位：

$(function() 
{ 
    var videos = 
    [ 
        { id : 'xJvt2SDV7ck', length : 60000 },
        { id : 'x6DD1k4BAUg', length : 125000 },
        { id : 'xJvt2SDV7ck', length : 166000 }
    ];

    function playNext()
    {
        var index = Math.floor(Math.random() * videos.length);

        alert( "Playing next movie => " + videos[index].id );

        var Video_back = new video_background($("#bgvideo"), 
        {
            "position": "absolute", //Stick within the div
            "z-index": "-1",        //Behind everything
            "loop": true,           //Loop when it reaches the end
            "autoplay": true,       //Autoplay at start
            "muted": true,          //Muted at start
            "youtube": videos[index].id,   //Youtube video id
            "start": 0,                 //Start with 6 seconds offset (to pass the introduction in this case for example)
            "video_ratio": 1.333,      // width/height -> If none provided sizing of the video is set to adjust
            "fallback_image": "videos/main.jpg",    //Fallback image path
        });

        setTimeout(function() 
        {
            playNext();
        }, videos[index].length);
    }

    playNext();
});
