Answer 1

The problem is that in IE, the event object is not sent as an argument of the handler, it is just a global property (window.event):

function getTarget(evt){
 evt = evt || window.event; // get window.event if argument is falsy (in IE)

 // get srcElement if target is falsy (IE)
 var targetElement = evt.target || evt.srcElement;

 //return id of 
 element when hovering over 
 or 
 if (targetElement.nodeName.toLowerCase() == 'li'){
  return targetElement;
 }
 else if (targetElement.parentNode.nodeName.toLowerCase() == 'li'){

    return targetElement.parentNode;
 }
 else{
    return targetElement;
 }
