Question

youtube javascript api中没有选项可以在手机上发布视频（通过id / url）吗？现在我有一个视频列表（通过php从youtube api下载的数据），我显示每个视频的缩略图，旁边有标题/日期/等。

理想情况下，我希望当用户点按缩略图时播放视频，但我无法在没有JS api创建视频的iframe的情况下（在叠加层中）找出如何执行此操作但是然后用户必须再次点击该叠加层来播放视频，因为api不允许在手机上进行自动播放。

有人知道解决方案吗？

Answer 1

如果您使用的是Android，则应使用Android Player。除此之外，您应该使用IFrame Player。由于Apple's own terms，自动播放在iOS中无效。

即使你找到了解决方法，你也会违反这些条款，我不会建议。

fiddle。这是代码：

<div id="timerText"></div>
<iframe id="player" width="420" height="315" src="http://www.youtube.com/embed/TP2iRzzamCk" frameborder="0" allowfullscreen></iframe>

<body >
