PS：data-target：指事件的目標

當data-toggle和data-target結合使用的時候(如上),表示將#myNav這個DOM元素以下拉菜單的形式去展示

<!--data-toggle="tab" 案例-->
<div style="margin:20px 50px;">
    <ul class="nav nav-tabs" role="tablist">
        <li role="presentation" class="active"><a href="#tba1" role="tab" data-toggle="tab">tab1</a></li>
        <li role="presentation"><a href="#tba2" role="tab" data-toggle="tab">tab1</a></li>
        <li role="presentation"><a href="#tba3" role="tab" data-toggle="tab">tab1</a></li>
        <li role="presentation"><a href="#tba4" role="tab" data-toggle="tab">tab1</a></li>
    </ul>
    <div class="tab-content">
        <div role="tabpanel" class="tab-pane active" id="tab1">tab1標簽頁對應內容頁面……</div>
        <div role="tabpanel" class="tab-pane" id="tab2">tab2標簽頁對應內容頁面……</div>
        <div role="tabpanel" class="tab-pane" id="tab3">tab3標簽頁對應內容頁面……</div>
        <div role="tabpanel" class="tab-pane" id="tab4">tab4標簽頁對應內容頁面……</div>
    </div>
</div>
