写个选项卡用bootstrap 几行代码就搞定了

<ul id="myTab" class="nav nav-tabs">    <li class="active">        <a href="#A" data-toggle="tab">       A选项卡        </a>    </li>    <li><a href="#B" data-toggle="tab">B选项卡</a></li>  </ul<div id="myTabContent" class="tab-content">    <div class="tab-pane fade in active" id="A">        <p>嗯 我这里是点 击A时所显现</p>    </div>    <div class="tab-pane fade" id="B">        <p>我这里是B选项卡显现的</p>    </div>  </div>
