我正在尝试为 HTML5 视频播放列表构建客户端解决方案，我无法在该项目中使用 AJAX 或 XML，这给我带来了一些问题。

基本上，我在一个视频中加载了一个视频标签，然后是一个名为“播放列表”的无序列表，其中包含我的所有视频。我让它工作，以便它可以在一个页面中播放 Mov 或 Ogv 作为播放列表，但我无法在列表中获得后备工作。我有点卡住了，我读过浏览器嗅探是旧的做法，但无法提出解决方案。任何帮助将不胜感激！

到目前为止，这是我的代码-

//Javascript
function run(link, player){
    $(player).children().eq(0).attr("src",link.attr('href'));
    $(player).children().eq(1).attr("src",link.attr('rel'));
    par = link.parent();
    par.addClass('active').siblings().removeClass('active');
    video[0].load();
    video[0].play();
 }

我稍微更改了您的 HTML，然后更改了“run()”函数以替换两个源标记。
