I have a webpage with about 20 different select boxes with different values selected in them. They are setup by a servlet. The user can change the selected value for any of the select objects and then hit an update button. At this point, the servlet updates itself and uses the newly selected options to display. What i want to do is somehow make a confirmation popup when the submit button is hit, that goes through all of these select objects, figures out which ones have changed from their original selection, and then asks the user to confirm the change for each of these with a yes/no popup possibly. If the yes is selected, then it would continue as normal, if not return false. Any suggestions how to do this. I know how to make the yes/cancel popup, but the tricky part is knowing which SELECT's have changed to request a confirmation on.
