一、问题
canvas.toDataURL()报错如下：
|
1 |
Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported |
二、解决
图片设置 ：crossOrigin属性
代码片段：img.setAttribute("crossOrigin",'Anonymous')
Uncaught DOMException: Failed to execute ‘toDataURL’ on ‘HTMLCanvasElement’: Tainted canvases may not be exported.
