get the display value of the reference field

[dev_K]

Hi All,

I have a catalog item where I use a reference field and a text field.

I would like the text field to have the exactly the same value as the reference field:

this works on the backend with the following client script:

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

    var groupDisplayValue = g_form.getDisplayBox('group').value;

    // Set the 'group_name' field to the display value of 'group'
    g_form.setValue('group_name', groupDisplayValue);
}

This does not work in ESC as I am getting a JS error that getDisplayBox() doesnt work.

I tried to use the 'getDisplayvalue()' instead but it does not work

@dev_K getDisplayBox doesn't work in case of Service Portal. You can get the display value via one of the following approaches.

1. GlideAjax: Make a server side script include method call using GlideAjax. This method should accept the sys_id of the assignment group as input and should return the display value/name of group based on sys_id

2. g_form.getReference: Make a g_form.getReference('<field_name>',callaback); method call and fetch the value of assignment group name field.

Hope this helps.

On client side you can use the script below to get Display value of reference field

g_form.getDisplayBox('<field name>').value;
