如何添加活动类到引导标签

Question

我有bootstarap药丸的问题。我想在功能上添加类活动到导航，但没有得到它。

下面是函数代码：

var tabsFn = (function() { 

    function init() { 
    setHeight(); 
    } 

    function setHeight() { 
    var $tabPane = $('.tab-pane'), 
     tabsHeight = $('.nav-tabs').height(); 

    $tabPane.css({ 
     height: tabsHeight 
    }); 
    } 

    $(init); 
})(); 

和HTML代码：

<div class="container"> 
     <div class="row "> 
      <div class="col-md-12"> 
       <div class="tabs-left"> 
        <ul class="nav nav-tabs col-md-4"> 
         <li><a href="#a" data-toggle="tab"><span>First</span></a></li> 
         <li><a href="#b" data-toggle="tab"><span>Second</span></a></li> 
        </ul> 
        <div class="tab-content col-md-8"> 
         <div class="tab-pane active" id="a"> 
          <div class="col-md-12">first</div> 
         </div> 
         <div class="tab-pane" id="b"> 
          <div class="col-md-12">second</div> 
         </div> 
        </div> 
       </div> 
      </div> 
     </div> 
</div> 

你能不能帮我写正确的功能？

这里我们要添加活动类到li标签。我在下面添加了jsfiddle。

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> 
 
<div class="container"> 
 
     <div class="row "> 
 
      <div class="col-md-12"> 
 
       <div class="tabs-left"> 
 
        <ul class="nav nav-tabs col-md-4"> 
 
         <li><a href="#a" data-toggle="tab"><span>First</span></a></li> 
 
         <li><a href="#b" data-toggle="tab"><span>Second</span></a></li> 
 
        </ul> 
 
        <div class="tab-content col-md-8"> 
 
         <div class="tab-pane active" id="a"> 
 
          <div class="col-md-12">first</div> 
 
         </div> 
 
         <div class="tab-pane" id="b">
