Client Script to show values based on selection

[HP8]

I know this topic has been asked a lot, but I have a specific set of requirements. I cannot use field dependencies because our category choices are used on more than one occassion.

Category field needs to display certain choices based on selection from our Product field, however it is not working.

Current client script setup:

Type: onChange

Field: Product

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
	if(g_form.getDisplayBox('product').value == 'Test Product'){
		g_form.clearOptions('category');
		g_form.addOption('category','666','Test Category');
		}
}

The Product field is a reference field to the cmdb_model:

Table: sn_customerservice_case
Field: product
Type: reference
Reference: cmdb_model

Category field an is out of the box integer field.

Hi @HP8 

Can you try with updated line of code.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

              if (isLoading || newValue === '') {

                        return;

                  }

                 if(g_form.getDisplayValue('product') == 'Test Product'){

                                   g_form.clearOptions('category');

                                   g_form.addOption('category','666','Test Category');

                  }else {

                      // add options if value is different 

                          }

}

Hi @HP8

Can you try this one 

if (newValue == 'product_value') {

        g_form.clearOptions('category');

        g_form.addOption('category', '666', 'Test Category');

    }
