#14174 — Removing event handler

If I have an onclick event handler I can "remove" it anywhere with

elem.onclick = null;

But if the handler is added using addEventListener which is in this sort 
of code

var a = function(o) {
   var transformer = function() {
     // do stuff
   }

   o.elem.addEventListene("click", transformer, false);

}(obj);

How can I remove the event handler outside of 'a'?

There is a removeEventListener function 
(https://developer.mozilla.org/en/DOM/element.removeEventListener) but 
you would need to store the event listener (function object) you passed 
in to addEventListener to be able to remove it later.
