title: radio button change only after confirm() returns true
body: <p>I've got a set of radio buttons in my html site. When the users changes the selection I show a dialog via the confirm('') function. I just want to change the selection if the user confirms the change - otherwise just cancel the event. My problem now is that I only got an event AFTER the value has been changes and the change is already done. How can i prevent this behaviour?</p>
