FUD revisited (1): Can you upload files with AJAX?September 30th, 2005
The short answer is: No.
But you can use AJAX to get information on the running upload, as long as your framework has functions that give information on current uploads; and your webserver doesn’t buffer upload data.
In Ruby on Rails that works like this: If you enable the UploadProgress module, Rails stores information about the progress in the session, so while the upload is doing its thing, you can poll the server via an AJAX call and get nice status information. The Upload itself is made via a “traditional” HTML upload form to a hidden IFRAME (the helpers will do all this hard work for you transparently!).
