If checkbox is checked auto populate reference filed

[Bidduam]

For a catalog item I'm creating I need to populate a reference field if checkbox is checked, with the current user.

Checkbox variable field:

checkbox_1

Reference field on sys_user table:

name_field

If checkbox_1 = true then name_field = current users name

I figure this would require a Catalog Client Script?

Not sure how to write it - if anyone is able to assist please?

Hi @Bidduam ,

You need to write a onchange

Thanks,

Hi @Bidduam ,

You can create an "onchange" client script on checkbox_1 variable - 

 if (newValue == 'true') {
        g_form.setValue('name_field', g_user.userID);
} else {
        g_form.clearValue('name_field');
    }

Ok thank you @Anirudh Pathak I've tried it and hasn't worked unfortunately

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    //Type appropriate comment here, and begin script below
    var check = g_form.getValue('checkbox_1');
    if (check == true) {
        g_form.setValue('name_field', g_user.userID);
    } else {
        g_form.clearValue('name_field');
    }
}
