Have a global variable/global flag in default set the value as 0 or 1. Have a listener for all the form data in that page. If any value is changed set the flag to true or 1. When the user clicks on a link. Just check the flag before triggering the confirmation. If the value is true or 1 show the confirmation box or dont show it.
