To fetch Userid of the Requested for user on the catalog form

[Rahul84]

Hi All,
I want to fetch the userid of the "Requested for" user from the catalog form.

example - I have a field Requested for on the catalog form.
I want to fetch the user id of this Requested for user on the Onchange catalog client script

for example - Requested for user is - Rahul Sharma , so i want the user of the user - Rahrma (combination of first and last name).

Pls help with solution.

If you ultimately only need the value, like user id to populate in another variable, try the code-less approach:

If you actually need the value (Rahrma) to further use in the same script, then you'll want to use a getReference with callback to lookup the value on the user table field based on the selected user.

@Brad Bowman   : can you please help me with the logic , I need to fetch the value of the (Requested for) user id and need to store it in the input variable. Instead of sys_id , I want user id. It will be great of you can help with the code/script.

var userID = g_form.requested_for.sys_id;
var inputs = {};
inputs['user_sys_id'] = userID; // String

[Brad Bowman]

function onChange(control, oldValue, newValue, isLoading) {
    g_form.getReference('requested_for', getUser);
}
 
function getUser(caller) { 
    var userID = caller.user_name
}
