hi guys.. i hope you can help me to solve my ajax problem cos i'm too new in ajax...
in my input.php, user has to enter some data and it will be passed to process.php

in process.php, after doing several quiries in mysql, the data will be sorted in table with several rows. each row will have a column containing a 'update' button. the button will be used to update the data with the same row.

what i wanna do is, when user click the 'update' button, it will triger update.php to do some quiries to update the row (using ajax). and at the same time, ajax loading image will be shown beside the update button. after the update process completed, the table will show the latest result (without refreshing the page).

i hope you can understand well my situation and plzz help me..
