Failed to execute 'toDataURL' on 'HTMLCanvasElement,在canvas.toDataURL()执行时候报错解决方案...

 

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   

 

视频的话同上，

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