AJAX Autosave functionality

Question

What\'s the best javascript library, or plugin or extension to a library, that has implemented autosaving functionality?

The specific need is to be able to \'save\'

Answer 1

Isn't all you need a timer that fires every x seconds? The callback function will do an AJAX postback to the server of the form with a "autosave=true" field added. Just handle this postback on the server and you are done.
