单击更改当前导航链接的类，而不是全部

Question

>我有引导选项卡，单击相应的菜单选项卡时将显示内容

我希望当单击特定菜单时，自定义类应该在该菜单而不是每个菜单选项卡上处于活动状态。

<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">
  <li class="nav-item">
    <a class="nav-link active" data-toggle="tab" href="#home" role="tab">Home</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#profile" role="tab">Profile</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#messages" role="tab">Messages</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#settings" role="tab">Settings</a>
  </li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="home" role="tabpanel">...</div>
  <div class="tab-pane" id="profile" role="tabpanel">...</div>
  <div class="tab-pane" id="messages" role="tabpanel">...</div>
  <div class="tab-pane" id="settings" role="tabpanel">...</div>
</div>
$(document).ready(function(){
    //function of collapse and tabpen   
    $(document).on('click','.nav-link.active', function(){
      var href = $(this).attr('href').substring(1);
    //alert(href);
      $('.tab-pane[id="'+ href +'"]').toggleClass('active');
    });
    $('.nav-link').click(function(){
     $('this').addClass('addplus');
    });
});

那里不需要两个不同的代码，在单个代码中，每件事都可以工作：-

$('.nav-link').click(function(){
 $('.nav-link').removeClass('addplus active');//first remove classes from previous nav link
 $(this).addClass('addplus active'); //remove '' around this
 var href = $(this).attr('href').substring(1);
 $('.tab-pane').removeClass('active');
 $('.tab-pane[id="'+ href +'"]').toggleClass('active');
});

演示示例：-

$(document).ready(function(){
  $('.nav-link').click(function(){
    $('.nav-link').removeClass('addplus active');
    $(this).addClass('addplus active');
    var href = $(this).attr('href').substring(1);
    $('.tab-pane').removeClass('active');
    $('.tab-pane[id="'+ href +'"]').toggleClass('active');
  });
});

.active{
  color:green;
  font-size:20px;
}
.addplus{
  font-style:italic;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="nav nav-tabs" role="tablist">
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#home" role="tab">Home</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#profile" role="tab">Profile</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#messages" role="tab">Messages</a>
  </li>
  <li class="nav-item">
    <a class="nav-link" data-toggle="tab" href="#settings" role="tab">Settings</a>
  </li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane" id="home" role="tabpanel">home</div>
  <div class="tab-pane" id="profile" role="tabpanel">profile</div>
  <div class="tab-pane" id="messages" role="tabpanel">messages</div>
  <div class="tab-pane" id="settings" role="tabpanel">settings</div>
</div>

注意：-

我重新创建了您的//function of collapse and tabpen函数，以便它也可以工作。您可以签入示例。谢谢
