Return false onSubmit not working on Portal.

[HrishabhKumar]

I'm using Async glideAjax in onSubmit catalog client script and allowing the submission of form on the basis of the script include response.

Below code is working for native UI, but not working on portal.

function onSubmit() {
    //Type appropriate comment here, and begin script below
    if (NOW._ajaxChecked) {
        // We have run our Ajax Checks, so we can continue on
        // and let our form submission continue
        NOW._ajaxChecked = null;
        return true;
    }
    var user = g_form.getValue('user');
    g_form.addErrorMessage('check 1');
    var si = new GlideAjax('CheckUser');
    si.addParam('sysparm_name', 'activeOrNot');
    si.addParam('sysparm_user_id', user);
    si.getXMLAnswer(function(ans) {
        g_form.addErrorMessage("ans is: " + ans);
        if (ans == 'false') {
            g_form.addErrorMessage('User is inactive');
            return false;
        }
        NOW._ajaxChecked = true;
        if (typeof g_form.orderNow != 'undefined') {
            // this is a catalog item
            g_form.orderNow();
        } else {
            // this will resubmit the form using the saved 
            // ui action that was originally clicked
            g_form.submit(NOW._action);
        }
    });
return false;
}

Don't paste links in the solution, I've already went through lot of articles. I'll appreciate updated code or suggestions.

@HrishabhKumar 

why not use onChange validation and throw error if user is inactive?

Hi @Ankur Bawiskar 

This is a demo code, Actual code contains some complex logic for which I have to use script include. But if this demo code can work, then I'll use the same logic in the actual code as well.

Hello @HrishabhKumar ,

Check your methods used in both client script and script include, this is can also cause some issues in portal. (e.g : getDisplaybox)
I'm not sure in your script as you've not pasted original script.
