javascript - 代码有问题

Question

var image = new Image();
image.src = canvas.toDataURL("image/png");
var link = document.createElement('a');
link.href = image;
link.download = 'Download.png';
document.body.appendChild(link);
link.click();

当我使用这个脚本时，它返回一个下载错误

(File not found)

为什么？

Answer 1

改变

link.href = image;

到

link.href = image.src;
