  <script>
   var title=document.getElementById('title');
   var content=document.getElementById('content');
   var spans=title.getElementsByTagName('span');
   var lis=content.getElementsByTagName('li');
   for (var i = 0; i < spans.length; i++) {
    spans[i].index=i;
     spans[i].onclick=function(){
      for (var j = 0; j < spans.length; j++) {
       spans[j].className='';
       lis[j].className='';
      }
       this.className='select';
       lis[this.index].className='show';
     }
   }
  </script>
</body>
</html>
这段代码的关键处在最后的两个for遍历和this指针，第一个for遍历是为每一个span按钮添加点击事件，而第二个for遍历是确定当前点击的是哪个按钮，相应的内容部分就很好控制出现和隐藏了；
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
