AJAX and sending form with fieldtype FILE

[Grzegorz Smith]

Hi all. Is it possible to upload FILE from form by AJAX ? I capture values
on form field and send by ajax call and all works perfect, but when i try
upload file it doesn'work. Maybe wron header is set? What do you think of
that?
Any help will be appreciated

Through the various technologies bunched under the buzzword "Ajax"? Yes.

Through XMLHttpRequest? No. You would have to read the file using JavaScript
and standard security settings prevent that.

The iframe hack is the way to go (or not use "Ajax", its rarely worth it).

I know the folks at 37 Signals just got that working on their last
project and they won considerable praise for a smooth implementation.
