Bootstrap jQuery 选项卡在下拉菜单中不起作用

Question

$('.dropdown-menu li').on('click', function(event){
  //The event won't be propagated to the document NODE and 
  // therefore events delegated to document won't be fired
  event.stopPropagation();
});
$('.dropdown-menu li').on('click', function(event){
  //The event won't be propagated to the document NODE and 
  // therefore events delegated to document won't be fired
  event.stopPropagation();
});

<li class="dropdown messages-menu">
  <!-- Menu toggle button -->
  <a href="#" class="dropdown-toggle" data-toggle="dropdown">
    <span class="caret"></span>
  </a>
  <div class="dropdown-menu">
    <ul class="nav nav-tabs" id="myTab">
      <li class="active"><a data-target="#home" data-toggle="tab">Home</a></li>
      <li><a data-target="#profile" data-toggle="tab">Profile</a></li>
      <li><a data-target="#messages" data-toggle="tab">Messages</a></li>
    </ul>

    <div class="tab-content">
      <div class="tab-pane active" id="home">Home</div>
      <div class="tab-pane" id="profile">Profile</div>
      <div class="tab-pane" id="messages">Message</div>
    </div>
  </div>
</li>

嘿，当我在dropdown-menu 之外单击时，我正在尝试开发我希望dropdown-menu 关闭的代码，我成功了，但是当我在@ 中插入nav-tabs 时出现问题987654327@ 选项卡不工作。

提前致谢

您将停止在单击 li 时传播事件，这会导致选项卡的选择中断。由于您需要停止事件传播以避免关闭下拉菜单，因此您必须手动选择选项卡。您可以通过以下代码实现。

$( document ).ready(function() {
$('.dropdown-menu li').on('click', function(event){
//The event won't be propagated to the document NODE and 
// therefore events delegated to document won't be fired
   event.stopPropagation();
 });

 $('.dropdown-menu li').on('click', function(event){
   //The event won't be propagated to the document NODE and 
   // therefore events delegated to document won't be fired
   event.stopPropagation();
 });

 $('.dropdown-menu > ul > li > a').on('click', function(event){
  event.stopPropagation();
  $(this).tab('show')
 });
});

更新片段

 $( document ).ready(function() {
$('.dropdown-menu li').on('click', function(event){
//The event won't be propagated to the document NODE and 
// therefore events delegated to document won't be fired
   event.stopPropagation();
 });

 $('.dropdown-menu li').on('click', function(event){
   //The event won't be propagated to the document NODE and 
   // therefore events delegated to document won't be fired
   event.stopPropagation();
 });
   
 $('.dropdown-menu > ul > li > a').on('click', function(event){
  event.stopPropagation();
  $(this).tab('show')
 });
});
