使用 Jquery 检索 Youtube 标签

Question

我试图弄清楚如何检索 Youtube 标签并在我的代码中使用它们，但我什至似乎无法检索任何信息。使用 , 或 ; 之类的分隔符检索标签的最佳方法是什么？

  var video_id='VA770wpLX-Q';

$.getJSON('http://gdata.youtube.com/feeds/api/videos/'+video_id+'?v=2&alt=jsonc',function(data,status,xhr){
alert(data.data.tags);
 });

这是 Json 对象的样子：

 {

}

Answer 1

Youtube 的 API 不再支持“标签”功能。
