Question

我几乎从他们的网站复制了代码。该选项卡启动完美，当我单击选项卡时，新面板被激活。但是，“活动”类不会应用于激活的选项卡。这是代码：

<ul class="nav nav-tabs" id="myTab" role="tablist">
    <li class="nav-item">
        <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>
    </li>
    <li class="nav-item">
        <a class="nav-link" id="profile-tab" data-toggle="tab" href="#profile" role="tab" aria-controls="profile" aria-selected="false">Profile</a>
    </li>
    <li class="nav-item">
        <a class="nav-link" id="messages-tab" data-toggle="tab" href="#messages" role="tab" aria-controls="messages" aria-selected="false">Messages</a>
    </li>
    <li class="nav-item">
        <a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
    </li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
    <div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab">...</div>
    <div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab">...</div>
    <div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab">...</div>
    <div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab">...</div>
</div>

我的js

$('#myTab a').on('click', function (e) {
    e.preventDefault()
    $(this).tab('show');
});

我刚刚在您的代码中添加了Bootstrap的CSS和JavaScript链接，并且效果很好。

<ul class="nav nav-tabs" id="myTab" role="tablist">
  <li class="nav-item">
    <a class="nav-link active" id="home-tab" data-toggle="tab" href="#home" role="tab" aria-controls="home" aria-selected="true">Home</a>

    <a class="nav-link" id="settings-tab" data-toggle="tab" href="#settings" role="tab" aria-controls="settings" aria-selected="false">Settings</a>
  </li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel" aria-labelledby="home-tab">...1</div>
  <div class="tab-pane" id="profile" role="tabpanel" aria-labelledby="profile-tab">...2</div>
  <div class="tab-pane" id="messages" role="tabpanel" aria-labelledby="messages-tab">...3</div>
  <div class="tab-pane" id="settings" role="tabpanel" aria-labelledby="settings-tab">...4</div>
</div>

bootstrap 4.3.1选项卡在我的项目中不起作用
