youtube javascript api 中是否没有选项可以在手机上启动视频（通过 id/url）？现在我有一个视频列表（通过 php 从 youtube api 下载的数据），我正在显示每个视频的缩略图，旁边有标题/日期/等。
理想情况下，我希望在用户点击缩略图时播放视频，但如果不让 JS api 创建视频的 iframe（在叠加层中），我无法弄清楚如何做到这一点，但是用户有再次点击该叠加层以播放视频，因为 api 不允许在手机上自动播放。
有人知道解决办法吗？

如果您使用的是 Android，则应使用 Android Player。 对于其他任何事情，您应该使用IFrame Player。 由于Apple's own terms，自动播放在 iOS 中无法运行。
即使您找到了解决方法，也违反了这些条款，我不建议这样做。

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