浏览器出现：Uncaught (in promise) DOMException: play() failed because the user didn't interact with the document first. https://goo.gl/xX8pDD　

原因：Chrome的autoplay政策在2018年4月做了更改。

解决办法：

第一步，在chrome浏览器中输入：chrome://flags/#autoplay-policy

第二步，在Autoplay policy中将Default改为No user gesture is required

第三步，重启Chrome
