Unbind keypress handler for specific combination only

Question

I have 2 keydown handlers:

$(document).bind('keydown', function(e) {
   if (e.keyCode == 75) {
       // handler1 strategy
   } else if (e.keyCode == 78) {
       // handler2 strategy
   }

});

How can I unbind one handler without affecting all the other keydown handlers?

Answer 1

You could create a plugin that maintains a map of key combinations, and associated functions. Whenever it sees a keydown event, it calls each matching function. Removal of an existing handler will be easy too.
