Bootstrap 4:从标签内打开标签(第二个链接)

Question

我正在使用Bootstra 4选项卡导航,如下所示:

<nav>
  <div class="nav nav-tabs" id="nav-tab" role="tablist">
    <a class="nav-item nav-link active" id="nav-home-tab" data-toggle="tab" href="#nav-home" role="tab" aria-controls="nav-home" aria-selected="true">Home</a>
    <a class="nav-item nav-link" id="nav-profile-tab" data-toggle="tab" href="#nav-profile" role="tab" aria-controls="nav-profile" aria-selected="false">Profile</a>
    <a class="nav-item nav-link" id="nav-contact-tab" data-toggle="tab" href="#nav-contact" role="tab" aria-controls="nav-contact" aria-selected="false">Contact</a>
  </div>
</nav>
<div class="tab-content" id="nav-tabContent">
  <div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">

      <a href="">LINK TO THIRD TAB</a>

  </div>
  <div class="tab-pane fade" id="nav-profile" role="tabpanel" aria-labelledby="nav-profile-tab">...</div>
  <div class="tab-pane fade" id="nav-contact" role="tabpanel" aria-labelledby="nav-contact-tab">...</div>
</div>

我现在想要使用第一个选项卡内容窗格中的链接从第一个窗格外部打开第三个链接窗格.

如果我正在使用选项卡导航中的链接(带有数据属性),则它不起作用.有没有办法用第二个链接打开标签？

下面的解决方案基于你在我的引用答案中已经看到的解决方案,但是这个解决方案正在扩展到你想要合并的滚动到功能.

从本质上讲,使用本机Element.scrollIntoView()javascript方法可以轻松实现scroll-to .

注意:在示例中,我为选项卡添加了一些边距,以便更好地展示功能.

$('.tab-link').on('click', function(event) {
    // Prevent url change
    event.preventDefault();

    // `this` is the clicked <a> tag
    var target = $('[data-toggle="tab"][href="' + this.hash + '"]');
    
    // opening tab
    target.trigger('click');
    // scrolling into view
    target[0].scrollIntoView(true);
});

#nav {
    margin-top: 90vh;
}

#nav-tabContent {
    margin-bottom: 90vh;
}

<nav id="nav">
    <div class="nav nav-tabs" id="nav-tab" role="tablist">
        <a class="nav-item nav-link active" id="nav-home-tab" data-toggle="tab" href="#nav-home" role="tab" aria-controls="nav-home" aria-selected="true">Home</a>
        <a class="nav-item nav-link" id="nav-profile-tab" data-toggle="tab" href="#nav-profile" role="tab" aria-controls="nav-profile" aria-selected="false">Profile</a>
        <a class="nav-item nav-link" id="nav-contact-tab" data-toggle="tab" href="#nav-contact" role="tab" aria-controls="nav-contact" aria-selected="false">Contact</a>
    </div>
</nav>

<div class="tab-content" id="nav-tabContent">
    <div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">

      <a class="tab-link" href="#nav-contact">LINK TO THIRD TAB</a>

    </div>
    <div class="tab-pane fade" id="nav-profile" role="tabpanel" aria-labelledby="nav-profile-tab">...</div>
    <div class="tab-pane fade" id="nav-contact" role="tabpanel" aria-labelledby="nav-contact-tab">...</div>
</div>
