Need help with Catalog client script to show the appropriate options

[New user1212]

Hi
I need help writing a catalog client script for my item.
The idea is that depending on the selected Resource Group, the appropriate Resource Sub Category will appear.
I created two Select box lists 1. resource_group 2. resource_sub_group but I can't write it correctly in the script because each version displays all options..

Select box type: Resource Group: Interims, Persistent Externals, Occasional Externals, Non-Executives

Select box type : Resource Sub Group, to display based on resource group selected : 

• Interims
• Interims - via Assured Partner
• Interims - Independents
• Persistent Externals
• Persistent Externals - via Assured Partner
• Persistent Externals - Independents
• Occasional Externals
• Occasional Externals - via Assured Partner
• Occasional Externals - Independents
• Non-Executives (no additional resource sub group dropdown required for this)

This is my script but no working..

@New user1212 Instead of handling this through a client script, you should instead make Resource sub category field dependent on the Resource Group field. Please refer to this documentation https://docs.servicenow.com/bundle/xanadu-platform-administration/page/administer/field-administrati... to know more about the steps to make a field dependent on another field.

Hope this helps.

you can't create a dependency for a catalog item, it has to be a client script

HI, @New user1212 
You can try the script below; it works properly on my instance.

 g_form.clearOptions('resource_sub_group');

    switch (newValue) {

        case 'Interims':

            g_form.addOption('resource_sub_group', 'ABC', 'Interims - via Assured Partner');

            g_form.addOption('resource_sub_group', 'XYZ', 'Interims - Independents');

            break;

        case 'Persistent Externals':

            g_form.addOption('resource_sub_group', 'AC', 'Persistent Externals - via Assured Partner');

            g_form.addOption('resource_sub_group', 'DC', 'Persistent Externals - Independents');

            break;

        default:

            break;

    }
