Missing javascript

I think there are some important things missing from Tapestry.js to release the full potential of Tapetsry 5 and AJAX. I have started working on a javascript class, TapestryExt, that extends the functionality of Tapestry.js.

My wish is to see all of this and more built in to tapestry.

 

/**
 * Commonly needed functions that are absent in the default Tapestry js lib.
 */
var TapestryExt = {
  /**
   * If the specified form listens for the Tapestry.FORM_PROCESS_SUBMIT_EVENT event
   * (all forms with a zone specified do), it will AJAX-submit and update its zone after.
   */
  submitZoneForm : function(element) {    
    element = $(element)
    if (!element) {
      Tapestry.error('Could not find form to trigger AJAX submit on');
      return;
    }
    element.fire(Tapestry.FORM_PROCESS_SUBMIT_EVENT);
  },
  /**
   * Trigger any link, zone or not. 
   * 
   * If no url is provided, the href attribute of element will be used.
   */
  triggerLink : function(element, url) {
    element = $(element);
    if (!url) {
      url = element.href;
    }    
    if (!url) {
      Tapestry.error('Unable to find url to trigger on element ' + element.id);
    }
    var zoneObject = Tapestry.findZoneManager(element);
    if (zoneObject) {    
      zoneObject.updateFromURL(url);
    }
    else {
      // Regular link
      // Note: this will skip all event observers on this link!
      window.location.href = url;
    }
  }  
}
