I'm not entirely sure what you mean by a page got stuck, but the best cure all for general iPad app weirdness is a soft reset.
Press an hold the home and power buttons at the same time. In ten or fifteen seconds an Apple Logo will appear. Your iPad is now resetting itself. Don't worry, it will take a few minutes but you won't lose any of your apps or data. Well, maybe whatever you were doing when the page got stuck.
Hope that does the trick for you.
