The standard way to attach event listeners is to use addEventListener but IE8 and earlier use attachEvent instead.

Here is my attachEventListener:

function attachEventListener(target, eventType, functionRef, capture)
{
  if (typeof target.addEventListener != "undefined")
  {
    target.addEventListener(eventType, functionRef, capture);
  }
  else 
  {
    target.attachEvent("on" + eventType, functionRef);
  }
  return true; 
};

I define it on the js file.
