CriticalThe element.attachEvent method was removed in Internet Explorer 11. Internet Explorer ≥ 11 2 pages
Use the W3 standard addEventListener() instead, using feature detection to support old versions of IE:

if (obj.addEventListener) {
    // use W3 DOM method if available (Chrome, Firefox, IE9+, Opera 7+)
    obj.addEventListener('click', myClick, false);
} else if (obj.attachEvent)  {
    // fallback for IE8 and earlier
    obj.attachEvent('onclick', myClick);
}  else {
    // fallback to DOM level 0 (only allows single event handler per event for each element)
    obj.onclick = myClick;
}
