GlideAjax script not reflecting output on form (no email displayed)

[sirijonna82]

I’m trying to use GlideAjax to fetch the Caller’s email from the sys_user table and display it when I select a Caller on the form.

I’ve written both the Client Script and Script Include, and the script runs without errors, but the output is not reflecting on the form (alert not showing any value). If anyone knows what's the issue, please help me.

Hi @sirijonna82 ,

It looks like your Script Include and Client Script have a few small syntax and naming issues, that’s why your GlideAjax call isn’t returning anything.

Here's a complete working code:
Script Include:

var getEmailId = Class.create();
getEmailId.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getEmailId: function() {
        var callerId = this.getParameter('sysparm_value'); // caller sys_id
        var user = new GlideRecord('sys_user');
        if (user.get(callerId)) {
            return user.getValue('email');  // always use getValue for consistency
        }
        return ''; // fallback
    },
    type: 'getEmailId'
});

Client-script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
    var ga = new GlideAjax('getEmailId');
    ga.addParam('sysparm_name', 'getEmailId'); 
    ga.addParam('sysparm_value', g_form.getValue('caller_id'));
    ga.getXMLAnswer(function(answer) {
        g_form.setValue('u_email', answer);
    });
}

The Output:
