通过Javascript / Ajax上传多个文件？

Question

Is there a way to select more than one files to upload when a user clicks the 'Browse' button, and have those files uploaded without refreshing the page?

This happens in Gmail, when you click to attach a file you can hold down CTRL and select multiple files.

Answer 1

there are only two ways of uploading a file without refreshing the page:

1. iframe

2. flash - it will give you the possibility to select multiple files at once

look at SWFUpload for more info

Answer 2

I recently faced a similar problem. We had been using Uploadify (http://www.uploadify.com/) to do uploads. I wrote a blog post on how to use Uploadify to perform multiple file uploads:

There are a couple of supported options:

• Use a single 'input' element and select multiple files.

• Use multiple 'input' elements to select a single file each.

Hope this helps.
