我有一个形象，用户画在画布上，我想保存的图像在服务器上。

I have an image that the user drew on a canvas and i want to save that image on the server.

这些线路在我的iPad很好地工作，但不是在我的Andr​​oid（版本2.3.3）的浏览器：

These lines work well on my ipad but not on my android(ver 2.3.3) browser:

var testCanvas = document.getElementById("sketchpad");  
var canvasData = testCanvas.toDataURL("image/png");

如果我提醒canvasData我只得到：

If i alert canvasData i only get:

数据：

我缺少的东西？是否有可能做的android或者我应该寻找其他的方法，插件等？

Am I missing something? Is it possible to do on android or should i be looking at other methods, plugins, etc?

不幸的是它不支持您的版本（我认为这是唯一支持ICS），看看这个问题的报道

Unfortunately it isn't supported in your version (i think it's only supported in ICS), have a look at this issue reported

目前被认为是某种JavaScript实现增加对它的支持，但我还没有尝试过自己

There is supposed to be some sort of JavaScript implementation to add support for it, but i haven't tried it myself
