jQuery中通过同一class获取点击tab页

<ul class="nav nav-tabs">
 <li class="active">
 <a href="#tab-1" class="stability-test" data-marker="tab1" data-toggle="tab" aria-expanded="true">tab1</a>
 </li>
 <li class="">
<a href="#tab-2" class="stability-test" data-marker="tab2" data-toggle="tab"aria-expanded="false">tab2</a>
 </li>
 </ul>

 $('.stability-test').click(function(e) {
 var $this = $(e.target);
 marker = $this.data('marker');
 });

$(".class").click(function(){
 alert($(this).index());
})//这个弹出的就是点击的class是第几个
