Hi Nagaraj,

 

I don't think control parameter is an OOTB field. Is this a custom field on your instance? A screenshot will be helpful.

Hi,

onChange() — runs when a particular field value changes on the form. The onChange() client script must specify these parameters.
  • control: the DHTML widget whose value changed.
  • oldValue: the value the widget had when the record was loaded.
  • newValue: the value the widget has after the change.
  • isLoading: identifies whether the change occurs as part of a form load.
  • isTemplate: identifies whether the change occurs as part of a template load.
