测试了就写上来，没技术含量 addEventListener

< html >
     < head >< title > dd </ title >
     < script type = ' text/javascript '   >
        
         function  fun1 ()  ... {
            var aa = arguments[0];
            aa.
        }
         function  fun2()  ... {
            alert(arguments.length);
        }
         function  addEvent ()  ... {
            var element = document.getElementById("haha");
            
            if(element.addEventListener) ...{
                element.addEventListener("click",fun1,false);
                element.addEventListener("click",fun2,false);
            }else ...{alert(element.addEventListener);
                element.attachEvent("onclick",fun1,false);
                element.attachEvent("onclick",fun2,false);
            }
        }
     </ script >
     </ head >
     < body >
         < p id = ' haha '  onclick = " addEvent() " > ddddddd </ p >
     </ body >
</ html >
