[jQuery] Ajax help


Hi.... I really have no clue how to get this done.... I have a form
with a few textboxes and a select box as well.... I want to have the
form fill itself if you happen to select one of the options of the
select box.... the data is at a mysql database.... I know this is
probably fairly complicated so you dont need to explain it step by
step, I would just appreciate a link to an example of this being
done.... thanks in advance
Just in case you want more backgorund info....
I have name, last name, ID, Telephone number and address textboxes
I also have the select box with a bunch of IDs of users that have
already been registered so I want it so that if I click on one of the
option IDs, it will pull up the data and autofill the form (making it
non-modifiable)
