添加跨域条件 crossorigin="anonymous"

【Redirect at origin 'http://xxx.xx.com' has been blocked from loading by Cross-Origin Resource Sharing

policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://sub2.xx.com' is therefore not allowed access.】

var img = new Image;

img.onload = myLoader;

img.crossOrigin = 'anonymous' ; //可选值：anonymous，*

img.src = 'http://....' ;

或者是HTML中 <img src="" id="" crossorigin="anonymous">

视频的话同上，<video width="320" height="240" controls="controls" crossorigin="anonymous"></video>

如果视频 video.crossOrigin = 'anonymous'; 报错的话，可以在标签上面加该属性。

个人博客：很多好用的 npm 包，可以看看 https://gilea.cn/
