Check form before submit with ajax

I'm building a web form with containing 3 fields. When the form is
submitted a search is done in a database, everything is ok.

Now, in order to help the user, I would like to display on the form
the number of results he will get if the form is submitted.
What's the best way to get this behaviour?

With a single field it's quite easy ($.get or $.load), but when I add
multiple checkboxes or multiple select, the construction I cannot
build the request anynmore...

Can someone give me some hints to build my form?

Thanks,

Use the $.ajax() function: in it among other you can specify a structure of
data to pass to your action page

Hi Salvatore,
Thank you for your response. Do you have a basic example to see how to
use this function?
Regards,
BMnt
