引导选项卡。通过jquery为当前选项卡添加边框

Question

这里是引导标签：

      <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li style="padding: 20px" role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li style="padding: 20px" role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    <li style="padding: 20px" role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
    <li style="padding: 20px" role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">

        <h1>Hello World</h1>

    </div>
    <div role="tabpanel" class="tab-pane" id="profile">Hello</div>
    <div role="tabpanel" class="tab-pane" id="messages">Some text</div>
    <div role="tabpanel" class="tab-pane" id="settings">Second text</div>
  </div>

</div>
        </div>

当前选项卡使用引导 javascript 自动激活类。

所以我想通过 jquery 为当前选项卡添加边框：

$('li').click(function () {
     if ($(this).hasClass('active')) {
         $(this).addClass('border-add')
     }
 })

我做不到。因为这段代码效果不好。如果单击其中一个选项卡边框将出现在当前选项卡上。但是，如果我单击另一个选项卡，我第一次单击的选项卡边框不会消失。 伙计们告诉我如何实现它。提前谢谢！

这可以在没有 JQuery 的情况下使用类来完成

li.active{
 border: 1px solid black;
}

/* Latest compiled and minified CSS included as External Resource*/

/* Optional theme */
@import url('//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-theme.min.css');

body {
    margin: 10px;
}
li.active{
 border: 1px solid black;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>

<!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li style="padding: 20px" role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li style="padding: 20px" role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>
    <li style="padding: 20px" role="presentation"><a href="#messages" aria-controls="messages" role="tab" data-toggle="tab">Messages</a></li>
    <li style="padding: 20px" role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>

  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">

        <h1>Hello World</h1>

    </div>
    <div role="tabpanel" class="tab-pane" id="profile">Hello</div>
    <div role="tabpanel" class="tab-pane" id="messages">Some text</div>
    <div role="tabpanel" class="tab-pane" id="settings">Second text</div>
  </div>

</div>
        </div>

你可能就在那儿。听起来您需要做的就是在添加之前删除 border-add：

$('li').click(function () {
  $('li.border-add').removeClass('border-add'); // remove from the one that has it first
  if ($(this).hasClass('active')) {
    $(this).addClass('border-add'); // then add the new one
  }
})
