element.attachEvent is unsupported Browser Compatibility Check

Description

The element.attachEvent method was removed in Internet Explorer 11.

Help

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; }
