Youtube 在手机上嵌入自动播放
我使用 React 将 iframe 与页面上的 youtube 视频设置为正确大小.一切正常，但手机无法使用自动播放选项.
I use React to set iframe with youtube video on page in correct size. All works well but for mobiles doesn't work autoplay option.
页面有什么有趣的地方，我有什么作为示例视频，效果很好.
What is interesting for page, what I have as example video it works perfect.
<iframe type="text/html" allowTransparency="true" height="100%" width="100%" preload="metadata" gesture="media" allow="encrypted-media" className="autoplay-iframe"
src={`https://www.youtube.com/embed/`+this.props.autoplay+`?autoplay=1&version=3&html5=1&hd=1&controls=0&loop=1&playlist=`+this.props.autoplay+`&playsinline=1&rel=0&showinfo=0&modestbranding=1&related=0&enablejsapi=1&origin=`+window.location.hostname} frameborder="0"></iframe>
以上是我的 iframe 代码.我剪切了部分 iframe 代码，但样式属性中只有样式.这对于自动播放并不重要.其他页面的最终网址相同.我不确定为什么.有什么提示可以解决这个问题吗?
above is my iframe code. I cut some part of iframe code but there are just style in styles attribute. It isn't important for autoplay. The same finally url for other page works. I'm not sure why. Any hints how I can solve this problem?
提前致谢.
推荐答案

You will not be able to implement this, since it is intentionally disabled to all mobile devices. The reason is for the user to save cellular data. It is also cited in this post.
视频自动播放不起作用的原因很简单.特点是在 iOS 和适用于移动设备的 Android.这样做的原因是为了节省移动用户的钱.此类设备(尤其是手机)经常使用收费的数据连接带宽.他们有数据限制，并且会产生费用.
The reason that video autoplay doesn’t work is simple. The feature is deliberately disabled in both iOS and Android for mobile devices. The reason this is done is to save mobile users money. Such devices (especially mobile phones) often use data connections that charge by bandwidth. They have data limits and going over results in a fee.
