How to get the value of the 'location' field from sys_user tale using client script

[synthia]

Hi All ,

I have written a catalog client script to populate the values of the user id logged into the off boarding form . However the user.location field is coming as null. The 'location' field is coming as 'https://dev78523.service-now.com/com.glideapp.servicecatalog_cat_item_view.do?v=1&sysparm_id=4dcaf086db227300100384da0b961990'

Can someone please help me fix it ? I have used DisplayBox.value but it was not working. Below is the code used onLoad

function onLoad() {
var user = g_form.getReference('requested_for',populateReqForDetails);

function populateReqForDetails(user) {
alert(user.location);
g_form.setValue('location',user.location);
alert(location);

}
}

Few follow up questions:

-Is it returning null for all users or just end-users?
If just end-users could be ACL issue preventing read access to location table.

-Are there any JavaScript errors in the browser console?
Other erroneous scripts could cause this script to fail.

-Does the user have a location?

I'm thinking this should be an onChange & on Load script:

function onChange(control, oldValue, newValue, isLoading) {

   if ( newValue == '') {
   	g_form.setValue('location','');
      return;
   }

   // Note the getReference is not Best Practice
   var user = g_form.getReference('requested_for',populateReqForDetails);

	function populateReqForDetails(user) {
		// Note that no display value is provided, resulting in another AJAX call to server
		g_form.setValue('location',user.location);

	}

}

Note: getReference() is actually not good practice, as it results in a round-trip to get the display value when populating reference fields and returns the entire record.
Most optimal would be to use GlideAjax, but this is a more advanced topic.
