未捕获的TypeError：canvas.toDataUrl不是函数

Question

I trying to resize an image and I am getting the uncaught TypeError message.

My code is:

var file =  canvas.toDataUrl("image/jpeg", 0.5);

Answer 1

I was being lame and missed that the function name was not toDataUrl but toDataURL.

So it should be written like:

var file =  canvas.toDataURL("image/jpeg", 0.5);
