When processing form on server just compare entered data and current
data from database to know that is changed. I use class for it who make
'changed' attribute for every db field so I can just check attribute.

All javascript code must be in one separate .js file. just link to it
on your form page and call procedure with one long-long parameter
describing all tests for this form. as here for example:

(see source, search for <form> tag)
