    }
  </style>
</head>
<body>
<div id="Tab1" class="tab clearfix">
  <div class="tab_title clearfix">
    <ul>
      <li><a target="_self" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" onmouseover="setTab('one',1,3)" id="one1">TAB1</a></li>
      <li><a target="_self" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" onmouseover="setTab('one',2,3)" id="one2">TAB2</a></li>
      <li><a target="_self" href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" onmouseover="setTab('one',3,3)" id="one3">TAB3</a></li>
    </ul>
  </div>
  <div class="tab_details clearfix">
    <div id="con_one_1" style="display: block;">con_one_1</div>

    <div style="display: none;" id="con_one_3">con_one_3</div>
  </div>
</div>
<script type="text/javascript">
  //tab切换效果
  function setTab(name, cursel, n) {
    for(var i = 1; i <= n; i++) {
      var menu = document.getElementById(name + i);
      var con = document.getElementById("con_" + name + "_" + i);
      menu.className = i == cursel ? "cur" : "";
      con.style.display = i == cursel ? "block" : "none";
