使用带有活动类的 js 切换选项卡答案

【问题标题】：Switching tabs using js with active class使用带有活动类的 js 切换选项卡
【发布时间】：2019-12-08 07:40:34
【问题描述】：

当我选择当前选项卡的选项之一时，我想切换选项卡。下一个选项卡内容进行切换，但不是选项卡本身。我已经按照这个例子 jsfiddle.net/ah97fo5m/。但是不能用我的代码来实现。我在这里做错了什么？

提前谢谢你。

【解决方案1】：

如果您只想在选择列表项之一时切换选项卡，您只需要弄清楚如何在兄弟之间切换 css 类。

我以在年份标签和汽车品牌标签之间切换为例。

首先，您需要为将链接到侦听器的 li 项目分配一些类（在您的示例中为 year-option）。

<ul class="tire-selector">
  <li><a data-toggle="pill" href="#pills-profile" class="list-group-item year-option">2018</a></li>
<li><a data-toggle="pill" href="#pills-profile" class="list-group-item year-option">2019</a></li>
 .......
 .......
</ul>

$(".year-option").click(function() {
  // first remove the active class from all the nav-links
  $('.nav-link').removeClass('active');
  // then apply active class on the target nav-link's id
  $('#pills-profile-tab').addClass('active')

  // same with the list containers, here you need to switch two classes
  $('tab-pane').removeClass('show active')
  $('pills-profile').addClass('show active')
});

当涉及到在某些操作上显示和隐藏自身的 ui 元素时，在大多数情况下，这是因为添加和删除了某些类。只需查找这些类并在其兄弟姐妹之间切换即可。
