title: jquery submit() ignores changes to input tags
body: <p>I have a jquery.submit() event handler. What I am trying to do is to catch the submit, and based on certain criteria, modify some of the values (actually, wipe them blank) of the input tags on the submitted form. When I step through with a debugger, I see that the fields are correctly being modified, but once the form submits, I see that it has submitted the original values. Is there a way to do what I am trying to do?</p>
  
  <pre>
  $('#views-exposed-form-find-a-rep-page-1').submit(function(event) {
      //$('.find-a-rep-search').click(function() {
          var address = $('#edit-geo-location');
          var countyField = $('#edit-field-county-value');
          //var stateField = $('#edit-state');
          var postalField = $('#edit-postal-code');
          var contact = $('#edit-field-rep-contact-name-value');
          var disabled = $('input:disabled');
          if(address.val() !== "") {
              var geocoder = new google.maps.Geocoder();
              geocoder.geocode( { 'address': address.val()}, function(results, status) {
                  if (status == google.maps.GeocoderStatus.OK) { //if the input wasn't total garbage
                      var county = '';
