OnSubmit Client Script not working in ServicePortal

[Shahebaz2]

Hello Experts, 

I want to understand how could we use the below script in catalog client script.

1  function onSubmit() {
2    if (g_scratchpad.isFormValid)
3        return true;
4    var actionName = g_form.getActionName();
5    doAsyncTask(function() {
6        g_scratchpad.isFormValid = true;
7        g_form.submit(actionName);
8    });
9   return false;
10 }

when I am using I got this error

onSubmit script error: ReferenceError: g_scratchpad is not defined:
function () { [native code] }

I am referring to this article -  https://hi.service-now.com/kb_view.do?sysparm_article=KB0779964 where the above solution mentioned.

how g_scratchpad.isFormValid is configured on catalog form?

Your comments would be apricated.

Thanks

It is available for Catalog Client script of UI Type service portal/mobile OOTB. You do not have to set up anything additional.
