bootstrap实现标签页，鼠标滑过激活当前选项卡。

要实现的效果

以下是代码

<ul class="nav nav-tabs" role="tablist" id="myTab">  <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>  <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>  <li role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>  <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li></ul><div class="tab-content">  <div role="tabpanel" class="tab-pane active" id="home">This home</div>  <div role="tabpanel" class="tab-pane" id="profile">This p</div>  <div role="tabpanel" class="tab-pane" id="messages">This m</div>  <div role="tabpanel" class="tab-pane" id="settings">This s</div></div>

以下是js代码

    <script type="text/javascript">       $(function () {          $('#myTab a').hover(function () {            $(this).tab('show');          });        })    </script>

完成了。
