How to show Loading form while waiting for response from script include?

[inderpal]

I have created a button on click of which a script include is called. I am using getXMLWait() for response to come from script include. It takes very much time to have the response from script include because of large processing in my script.
So for a while it looks like nothing is happening after clicking that button.
Is there any way i can show loading form or processing meanwhile on the screen?
i have used showLoadingDialog() method before calling my script include but it is not working..

My script is:

function XYZ() {

showLoadingDialog();

  var sub = new GlideAjax("XYZOrder");

  sub.addParam('sysparm_name', "Order");

  sub.getXMLWait();

  var yes = sub.getAnswer();

  hideLoadingDialog();

}

Please Help!!

I've run into this as well, some browsers don't load it for it processes to quickly; I've found a workaround with using setTimeout()

JavaScript Timing Events

Could try that and see if it assists? (long shot but may work).

Thanks Erik Brostrom.

It is working when i am giving delay of 1 sec.

Have you tried using the async getXML method like:

function XYZ() {

   showLoadingDialog();

   var sub = new GlideAjax("XYZOrder");

   sub.addParam('sysparm_name', "Order");

   sub.getXML(function() {

   var yes = sub.getAnswer();

   hideLoadingDialog();

   });

}

Sync or Async showLoadingDialog(); works. I have used in many of my implementation
