javascript - 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。

我得到了这段代码，可以播放单个 youtube 视频。但是我想制作一个视频列表并随机播放它们......我现在对 Javascript 不太好，所以我真的很感激这方面的一些帮助......

现在我有这个....

我想制作一个视频列表并像随机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 个视频(单循环)。 我想让它在第一个视频结束时转到另一个视频..

我们将不胜感激!感谢您的宝贵时间!

以下答案基于无法确定视频何时结束的事实。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();
});
