Attaching a client-side script (aka applet) to the form is a general way of
achieving your aims. The latest release of SurfIt!, v0.4a, has support
for client-side scripting for forms. Check out:

Unfortunately, applet-enabled browsers are not in wide deployment as yet,
but it looks like they will be in time (Java-enabled browsers at any rate...)
