蹊跷的代码

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，它返回我下载错误

(File not found) 

为什么？

Answer 1

变化

link.href = image;

到

link.href = image.src;
