通过ajax post（jQuery）发送输入类型=“文件”表单数据

Question

I want to send the post data from an input like this:

<input type="file" name="userFile" id="userFile"/>

?

I need to send it via ajax using $.post to a specified file.

How can I do this?

Answer 1

Without HTML5, this isnt possible, and the html5 solution won't work in all browsers without workarounds for browsers that don't support it.

The most cross-browser way to solve this is to not use ajax and to instead post to a hidden iframe.

Or use a plugin such as uploadify .

Most if not all of the jQuery plugins that implement this use either flash or hidden iframes when the html5 method isn't supported.

Answer 2

使用jquery.form插件...
