Do you mean that *instead* of doing an HTML submit (which always does
a GET or POST fetch of the whole page) you want to do an Ajax
operation which only refereshes the div?

In that case, don't use a 'submit' input at all: use a button (you can
call it 'submit' if you like) and observe it with a 'click'.
If you are concerned about getting all the inputs from from form, see

Either include some Javascript in the HTML you send from the Ajax
request, to set up an event handler (use Element.observe() rather than
the HTML 'onClick' property - in this case you will need to set
'evalScripts: true' in your Ajax.Updater options

Or, the better solution is to attache a handler to an element which
doesn't change (your <div> probably) and delegate handling.

If you say

$('mydiv').observe('click', function(ev) {
  var input = ev.findElement('input');
  if (input) ...

then any pick on your div, irrespective of how many times its contents
have changed, will call that function (which I've written inline, but
could be a named function), which will check whether the pick was
actually inside an <input> element - any <input> element - and if so
take action.
