Using AJAX, can I save form info to db on event onLostFocus?

[jcavard]

Hi!

I am designing a PHP/MySQL app to edit Plant information. My boss would like the app to automatically save as the user exits the textbox or change anything in the form (no need for a submit then) is this something possible with ajax??

It is possible, but don't get rid of the submit buttton. Not all users will have Javascript enabled. Also, a form without a submit button will be a bit disconcerting for the users.

indeed, that's a fact, really disconcerting.
as for the disabled javascript, this means AJAX wouldn't be working at all in that case? is there any way to force it? or anything?

BTW, I found NAJAX class on PHPClasses.org that allows to call PHP function on javascript event, exactly what I meant.. thank you!
