value of radio button that was deselected?

value of radio button that was deselected?

There may be a function or somethin for this, but is there anyway to get the name/id/value of the radio button that became deselected?

So, lets say there are 4 radio buttons, and button 1 was selected, now the user selects button 3. I know how to get the values of the button that was selected ( $('input:radio').click(function() ). How do I get the value of the button which was deselected in the processes.

Thanks guys!
