javascript事件绑定和删除功能代码
网上搜来的,看样子不错,记一笔。//------------------------------------ // heavily based on the Quirksmode addEvent contest winner, John Resig // addEvent function addEvent(obj,type,fn){ if(obj.addEventListener) obj.addEventListener(type,fn,false); else if(obj.attachEvent){ obj["e"+type+fn]=fn; obj[type+fn]=function(){obj["e"+type+fn](window.event);} obj.attachEvent("on"+type,obj[type+fn]); } }
//------------------------------------ // removeEvent function removeEvent(obj,type,fn){ if(obj.removeEventListener) obj.removeEventListener(type,fn,false); else if(obj.detachEvent){ obj.detachEvent("on"+type,obj[type+fn]); obj[type+fn]=null; obj["e"+type+fn]=null; } } |
