I want to get logged in user information in a client script.

I would like to get the constant for a logged in user in a client script.

How do I get the email address, user ID, etc.?

Hi @Takumi Togashi ,

The g_user object can be used only in UI policies and Client scripts. Contrary to its naming, it is not truly a user object. g_user is actually just a handful of cached user properties that are accessible to client-side JavaScript. This eliminates the need for most GlideRecord queries from the client to get user information (which can incur a fairly significant performance hit if not used judiciously).

g_user Property or Method	Return value
g_user.userName	User name of the current user e.g. employee
g_user.firstName	First name of the current user e.g. Joe
g_user.lastName	Last name of the current user e.g. Employee
g_user.userID	sys_id of the current user e.g. 681ccaf9c0a8016400b98a06818d57c7
g_user.hasRole()	True if the current user has the role specified, false otherwise. ALWAYS returns true if the user has the 'admin' role. Usage: g_user.hasRole('itil')
g_user.hasRoleExactly()	True if the current user has the exact role specified, false otherwise, regardless of 'admin' role. Usage: g_user.hasRoleExactly('itil')
g_user.hasRoles()	True if the current user has at least one role specified, false otherwise. Usage: g_user.hasRoles('itil','admin')

Also, Refer to the thread for example : https://www.servicenow.com/community/developer-articles/get-user-details-based-on-the-logged-in-user...

Hi Takumi,

In addition to what is suggested in comments before you can use a combination of Script include (write once & use as many time in as many places) & Client script for the same.

Refer article link for a check.

HI @Takumi Togashi ,
I trust you are doing great.
to retrieve the email address and user ID of a logged-in user in a client script in ServiceNow, you can use the following code:

// Get the current user's email address
var emailAddress = gs.getUser().getEmail();

// Get the current user's sys_id (user ID)
var userID = gs.getUser().getID();
