Dot walking through multiple tables in client script

[Kyle Wiley]

I am trying to dot walk through multiple tables in an onChange client script on the Incident table.  When the Caller field on the INC form changes, I want to reference the sys_user table to see what department the Caller is in.  The field that I am trying to use on the Department table is u_department_group.

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

   if (isLoading || newValue === '') {

      return;

   }

var caller = g_form.getReference('caller_id');

var dept = g_form.getReference('caller_id').department;

   if (newValue) {

  confirm(caller.name);

  confirm(dept);

   }

}

caller.name prints out the user's full name as it displays in the sys_user table but when I try to print out dept, the only value I get is the sys_id.  I cannot get the department name to display or any other field on the Department table to display anything.

Is this possible in a client script?

That is because department is a reference field on the user record, so you have to dot-walk further to ...department.name

[Kyle Wiley]

I've tried that. It just returns undefined. Is that because the department field is a reference field as well?

[jamesjurden]

If you just want to set the location field on the form then the sys_id should work fine the way you have it. The field should show the display value automatically.

Please try using a GlideRecord like below:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
       return;
   }
   var caller = g_form.getReference('caller_id');
   var dept = caller.department;
   if (dept) {
       var grDept = new GlideRecord('cmn_department');
       if (grDept.get(dept)) {
           confirm(caller.name + ' works at ' + grDept.name);
       }
   }
}

Hope this helps.
