推荐答案

没有，那是不可能用JavaScript做到这一点。

No, it isn't possible to do this with javascript.

为了给AJAX的感觉，但是，你可以提交一个表单到一个隐藏的iframe和输出脚本结果，那么过程从那里。谷歌 AJAX的iframe上传 并开始从那里。

In order to give the 'AJAX' feel, however, you can submit a form to a hidden iframe and output the script results to it, then process from there. Google ajax iframe upload and get started from there.

如果你正在使用jQuery，也有 表格插件 它会自动创建这个iframe的你，如果你的表单中有任何文件中的字段。我没有用它来做到这一点，但我听说好东西。

If you are using jQuery, there is also the Form plugin which will automatically create this iframe for you if your form has any file fields in it. I haven't used it to do this, but I've heard good things.

正如在评论中，也可以用类似的非常流行的 SWFUpload的 实现与Flash预期的效果。

As pointed out in the comments, you can also use something like the very popular SWFUpload to accomplish the desired effect with Flash.
