在IE中本地保存画布 [英] saving canvas locally in IE

问题描述

我想在IE中本地保存画布。

Hi I want to save a canvas locally in IE.

  var img = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");

我无法通过以下方式下载。

I couldn't manage to download it with following ways.

1) document.execCommand("SaveAs"..
2) window.location.href = img;
3) $.fileDownload(img);  // jquery download file library-
4) canvas2image // cross domain problem.

有没有办法在IE中本地保存画布没有base64或跨域问题？非常感谢。

Is there a way to save canvas locally in IE without base64 or cross domain problem? Thank you very much.

推荐答案

好吧，看起来这在IE中不起作用，列出它，我将提供一个例子。此操作使用 HTML5 下载属性（在这里更多），并允许用户点击链接

Well, it looks like this doesn't work in IE either, but since you've not listed it, I'll provide an example. This uses the HTML5 download attribute (more here), and allows the user to click a link which then downloads a file.

<a href="data:text/html;base64,PCF...." download="file.png"></a>
