On W3C browsers you should be able to "capture" the "change" event
without problems.
var handler = function(e) { alert(e.target); /* e.target.form.submit(); */ };
document.addEventListener('change', handler, true);
On other non-compliant browsers you can use the event "bubbling" phase
to check the parent form for the "click" event or the activation event
and do your processing on the control elements to check their state
and values.
