Perspective pop up confirm

I have a view with various items that are saved to a table once the user presses save. I want to add a pop up so they have to confirm to save or exit, that’s easy enough but do I need to pass all the values through to the pop up or is there an easier way? The pop up has a exit button that closes the popup and a save button that performs the sql update.
