Hi @abhisekransingh 

Please use below code,

I am taking reference id caller field on incident form. Please replace as per your requirement.

var student = g_form.getReference('caller_id'); //works only your field type is reference

alert(student.user_name);

Please mark it as correct If this helps you.

Thanks,

Vennela

Hi @abhisekransingh 
use the GlideAjax or GlideReocrd or g_form.getDisplayBox('u_student').value(this might not work in portals)

Hi @abhisekransingh ,

getDisplayValue() won't work in client scripts. Also, you will find some API that are not showing because maybe ServiceNow has not documented it but it will work and fulfill your requirement.

In ServiceNow Docs you can find the API:

Try the below:

var stu_value=g_form.getDisplayBox('u_student').value;
alert(stu_value);
