Ie9 Quirks Mode Doesn't Pass Event Parameter To Event Handler

I have a problem with the IE9 quirks mode. I have registered an oncahnge-event to an input element. This works so far, but in IE9 our site goes to quirks mode (it is as it is) and

Solution 1:

I suppose the event is global in IE quirks mode, so checking the event parameter and assign window.event if it's undefined would solve the problem:

function myChangeMethod(evt){
  //In IE 9 quirks mode "event" is undefined...
  evt = evt || window.event; //<== HERE
  // additionally in quirks mode evt.target is evt.srcElement, 
  // so if needed you could assign evt.target as:
  var originator = evt.target || evt.srcElement;
  if(evt){
    //do stuff
  }
}
