          modal: true,
          buttons: {
              'Confirm submit': function() {
                  document.______???????_____.submit();
              },
              Cancel: function() {
                  $(this).dialog('close');
              }
          }
      });
  $('.allForms').submit(function(){
        $('#dialog-confirm').dialog('open');
