enabling and disabling button

[joques]

I have a form in coffeekup (using express, etc.) with some fields and two buttons (update and close). I would like to enable the update button only if a change occurred in the fields, otherwise I should keep it disabled. I tried to use jQuery, but I am not really getting around doing. Does any have any idea how to go about this? thanks in advance José
