Just like the way u get handle of other fields using JavaScript, but make sure u check the following property on 2nd tab of Form Properties"Generate HTML for ALL Fields"

Or alternatively use computed text in javascript if you have fields you definitely don’t want user’s as you can’t be selective with ‘generate html for all fields’
