求大手找出我的問題所在，基本上跟老師的沒什么區別啊，但就是沒反應，下面是我的代碼

<script type="text/javascript">
function showmes(){
alert("媽的智障！");
}
var eventUtil{
addHandler:function(element,type,handler){
if(element.addEventLisenter){
element.addEventLisenter(type,handeler,false);
}else if(element.attachEvent){
element.attachEvent('on'+type,handler);
}else{
element['on'+type]=handler;
}
}
removeHandler:function(element,type,handeler){
if(element.removeEventLisenter){
element.removeEventLisenter(type,handeler,false);
}else if(element.detachEvent){
element.detachEvent('on'+type,handler);
}else{
element['on'+type]=null;
}
}
}
eventUtil.addHandler(btn,'click',showmes);
