据我所知，HTML5视频的Andr​​oid无法自动播放。由于它代表我的影视作品在设备上，只有当用户点击播放按钮。

I understand that html5 video on android cannot autoplay. As it stands my video works on the device only when the user clicks on the play button.

<video width="640px" height="360px" src="media/video/Moments_of_Everyday_Life.mp4" controls id="video"></video>


<script type="text/javascript">
    $(function(){
        var video  = document.getElementById('video');
        video.play();
    });
</script>

为什么会这样行不通？什么是点击播放和使用.play的）这个方法（之间的性差异？

Why would this not work? And what is the diference between clicking play and using this method of .play() ?

更新

这适用于我的dekstop，只是没有对Android设备。

This works on my dekstop, just not on the android device..

推荐答案

它不会出于同样的原因浏览器阻止呼叫到的window.open（），因为工作允许它可以让Web开发人员，颠覆用户preference不自动播放媒体（或打开弹出窗口）。

It wouldn't work for the same reason browsers block calls to window.open(), because allowing it would allow web developers to subvert user preference not to auto play media (or open popup windows).

点击播放，使用这种方法的区别，正是你所说的话：点击。这些排序的电话被允许在点击事件，但不普遍。

The difference between clicking play and using this method is exactly what you've said: the click. These sort of calls are allowed in click events, but not generally.
