JS detecting event support in browsers

As you may know there is no easy way of detecting which elements supports which events across browsers. Kangax from Perfection Kills has come up with a very clever way of detecting them.

JavaScript

 
  var isEventSupported = (function(){
    var TAGNAMES = {
      'select':'input','change':'input',
      'submit':'form','reset':'form',
      'error':'img','load':'img','abort':'img'
    }
    function isEventSupported(eventName) {
      var el = document.createElement(TAGNAMES[eventName] || 'div');
      eventName = 'on' + eventName;
      var isSupported = (eventName in el);
      if (!isSupported) {
        el.setAttribute(eventName, 'return;');
        isSupported = typeof el[eventName] == 'function';
      }
      el = null;
      return isSupported;
    }
    return isEventSupported;
  })();

Use

isEventSupported(<"Type of Event>")
