    addEvent() function.addEvent: function(obj, type, fn) {

        'use strict';

        if (obj && obj.addEventListener) { // W3C

            obj.addEventListener(type, fn, false);

        } else if (obj && obj.attachEvent) { // Older IE

            obj.attachEvent('on' + type, fn);

        }

    }, //  In the Source Code

 

addEvent : function(obj,type,fn){
