[development] Passing a client value back to Drupal

[jeff at ayendesigns.com]

Getting warm. Since I'm replacing the click handler, I decided not to 
mess with url at all and to just add another data pair to the data being 
passed, and treat it as 3 parms in the module.

I note that both 'modal' and 'ajax' are being loaded, and that the 
binding is actually do modal (from what I see in firebug). Looking at 
the code, modal link click is just a small lead-in to ajax link click, 
so I think I need to unbind the modal click handler and bind my own, 
having it call my own ajax link click function.

The unbind works. The bind does not. I start the bind with an alert, and 
when I actually click the link, it attempts to make a page change (no 
ajax bind, and no alert).  Here is what I have:

/**
  * Unbind the CTools click event handler then add our own
  */
$(document).ready(function() {
     $('a.ctools-use-modal').unbind('click');
     $('a.ctools-use-modal-processed').unbind('click');
     $('a.ctools-use-modal:not(.ctools-use-modal-processed-My)', context)
           .addClass('ctools-use-modal-processed-My')
           .click(Drupal.CTools.Modal.clickAjaxMyLink);
});

Drupal.CTools.Modal.clickAjaxMyLink = function () {
   // show the empty dialog right away.
   Drupal.CTools.Modal.show(Drupal.CTools.Modal.getSettings(this));
   Drupal.CTools.AJAX.clickAJAXMyLink.apply(this);
   if (!$(this).hasClass('ctools-ajaxing')) {
     Drupal.CTools.Modal.dismiss();
   }

   return false;
};

/**
  * Generic replacement click handler to open the modal with the
   destination
  * specified by the href of the link.
  */
Drupal.CTools.AJAX.clickAJAXMyLink = function() {
alert('made it');
   if ($(this).hasClass('ctools-ajaxing')) {
     return false;
   }

   var url = $(this).attr('href');
   var object = $(this);
   $(this).addClass('ctools-ajaxing');
   try {
     url = url.replace(/\/nojs(\/|$)/g, '/ajax$1');
     $.ajax({
       type: "POST",
       url: url,
       data: { 'js': 1, 'ctools_ajax': 1, 'body': 
CKEDITOR.instances['edit-body'].getData()},
       global: true,
       success: Drupal.CTools.AJAX.respond,
       error: function(xhr) {
         Drupal.CTools.AJAX.handleErrors(xhr, url);
       },
       complete: function() {
         $('.ctools-ajaxing').removeClass('ctools-ajaxing');
       },
       dataType: 'json'
     });
   }
   catch (err) {
     alert("An error occurred while attempting to process " + url);
     $('.ctools-ajaxing').removeClass('ctools-ajaxing');
     return false;
   }

   return false;
};
