Hello,

I make calculations and many thinks in a page that result in a
javascript table file. I know how to create a CSV string from this
table in JS, but I would like that when the user click on a given
button, the script launchs and generate a file that is dowloadable
using a dialog box without requesting server.

Can you tell me if it is possible and how I can do that ?

This must be compatible with IE6 (and higher) and latest release of
FF.

Thanks a lot for you help !

It is not impossible, using data URLs.

IE 6 has no support for data URLs, so it looks like you will need to
use server-side code.

In IE6 you can use document.execCommand("SaveAs", null, "FileName");

Here an example for saving files in IE 6:

http://4umi.com/web/javascript/filewrite.php?txt=3DThis+is+some+sample+text=
..%0D%0AThis+is+a+new+line.&filename=3DC%3A%5CMy+Documents%5Cfilename&ext=3D=
utf-8#

For the OP, here's an example of prompting a download with a data uri:

http://thenewobjective.com/temp/save.html

For a plain text file, the uri will look something like this:
"data:text/octet-stream," + FileContents

Good one!

Next step is to take both and create a cross-browser function and test 
it in as many browsers.

Questions about your code:
1) why  use - document.body.insertBefore( w ); - instead of appendChild?
3) why use window.open?

Joe User is not going to be able to type or to copy-paste the target file 
path, though.

The 4umi.com website is not my domain, only the thenewobjective.com
domain is.

Perhaps, to avoid IE's "Operation aborted" error?
