ServiceNow Things to Know 114: g_form.setValue() best practice usage for Reference Field

[PrashantLearnIT]

Hello Everyone,

g_form.setValue() is one of the most commonly used client side API in Service Now. While using it on reference or list fields, it is a best practice to pass the display value as the 3rd parameter along with its sys_id. Without a display value, the API makes an additional synchronous server call to fetch it and adds to the performance.

For Reference fields

g_form.setValue('caller_id', '5137153cc611227c000bbd1bd8cd2005', 'Fred Luddy');

For List fields

g_form.setValue('work_notes_list', '46d44a23a9fe19810012d100cca80666,681b365ec0a80164000fb0b05854a0cd', 'Beth Anglin, ITIL User');

Note: You will need to return the display value along with its sys_id when you fetch data from server.
