Removing Option from the Choice list

[Kaleem A]

Hi All,

I have two fields on the form "Category" and "Subcategory".   Subcategory is dependent on Category field. Here I'm trying to remove the option from the subcategory based on the option selected in the category field.   I have onChange Client script as below. It doesn't seem to be working. Can someone help me on this.

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

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

      return;

    }  

  var incident_category = g_form.getValue('category');

  if(incident_category == 'Proactive'){

  g_form.removeOption('subcategory','system generated');

  }

}

The only downside to this is maintainability. If you ever change the choice list, you will also have to change the hardcoded values in the script.

Hi Akbar,

Please go through the following article by Mark Stranger on ServiceNow Guru.

It was really helpful for me.

Also Dependent Logic Executes Later than Client SCript .....so CS is not affecting in any ways.
