How can I auto populate email field, when user field filled.

[ND7]

Dear Expert,

How can I proceed with this requirement? Once the user field name is entered, the email field should automatically populate. Please help Thank you so much. Appreciate your help.

did you try putting alerts ?

make sure your back end names of variables are correct  

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
 
    var user = g_form.getReference('name', userDetails);
    
    function userDetails(user) {
alert(user.email);
        g_form.setValue('email', user.email);
    }
}

Hello, assuming you are doing this on a table, using a business rule to do this would be very simple. For your table that your two fields live on, you can create a business rule to set the value of email when a user is picked in your reference field.

Example:

Let me know if you're trying to do this on a catalog item through the service portal instead and I can help with that too.

var user = g_form.getReference('field_name', function(user))
{
g_form.setValue('field_name', user.email.toString())
});

Hello,

can you share the script with which you tried to auto populate ?

[ND7]

on the form, I would like to type Name and email to be filled in automatically. 

but onChange did not work.

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

    //Type appropriate comment here, and begin script below
    var user = g_form.getreference('name', function(user) {// map the correct field
        g_form.setValue('email', user.email.toString());// map the correct field
    });

please help 😞

Hello, change the highlighted 'variable name' in your final picture to the 'name' field. Make sure you set the 'UI Type' to 'All' as well, just in case.

Then change your script to look like this and it should work:
