 <style type="text/css">
  li {
    height: 25px;
    line-height: 25px;
    background: rgba(0,0,0,0.5);
    border-bottom: 1px solid red;
  }
  a {
    text-decoration: none;
    font-size: 16px;
  }
 </style>
 </head>
 <body>
 <div>
  <ul>
    <li>
      <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
        <div class="index">
        0
        </div>
      </a>
    </li>
    <li>
      <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
        <div class="index">
        1
        </div>
      </a>
    </li>
    <li>
      <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
        <div class="index">
        2
        </div>
      </a>
    </li>
    <li>
      <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
        <div class="index">
        3
        </div>
      </a>
    </li>
    <li>
      <a href="javascript:void(0);" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
        <div class="index">
        4
        </div>
      </a>
    </li>
  </ul>
 </div>
 <script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
 <script type="text/javascript">
    $(function(){
      $(".index").on("click",function(){
          var $target = $(this);
          console.log($(".index").index($target));
      });
    });
 </script>
 </body>
</html>
