如何用js判断是否点击？

只在ie下运行可以把event参数去了
<div id="unChosed">
<ul>
<li onclick="clickitem(event)">- A </li>
<li onclick="clickitem(event)">- B </li>
<li onclick="clickitem(event)">- C </li>
</ul>
</div>
<script>
function clickitem(e){
  var evt=e||window.event;
  var srcEl=evt.target||evt.srcElement;
  var oParNode=srcEl.parentNode;
  var aLis=oParNode.getElementsByTagName("li");
  var i,nLen=aLis.length,nIndex=-1;  for(i=0;i <nLen;i++){
      if(aLis[i]==srcEl){         
          nIndex=i;
          break;
      }
  } 
  alert(nIndex);
}
</script>

    不好意思，
    请楼主自己把 clickitem(e) 里的参数 e 去掉。
    这个没用。
