引导 4 选项卡.js活动状态卡住

Question

4 个tab.js示例中的 2 个在 CodePen 和本地 html 文件中对我不起作用。在"nav"示例中，下拉列表中的项目保持活动状态，单击方式后无法再次访问。垂直选项卡中的所有项目也是如此：https://codepen.io/DannyJoris/pen/MvqMEW

起初，我认为提供的代码片段中可能存在错误，但是即使我使用检查器工具复制工作示例的标记，错误仍然存在。这让我觉得我包含 Bootstrap 文件的方式有问题。

这些是包含的 CDN 文件：

.CSS：

• https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.6/css/bootstrap.min.css

JavaScript：

• https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js
• https://cdnjs.cloudflare.com/ajax/libs/tether/1.4.0/js/tether.min.js
• https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.0.8/popper.min.js
• https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.6/js/bootstrap.min.js

在macOS 10.12.6，Chrome 60和Firefox 55上进行测试

编辑：使用Bootstrap 3.3.7：https://codepen.io/DannyJoris/pen/VzEZmw 时它确实有效，所以它一定是Bootstrap中的一个错误。

Answer 1

如果您的问题与垂直和药丸有关，我可能会建议添加以下处理程序：

$('.nav-pills > a').on('shown.bs.tab', function (e) {
$(this).siblings().removeClass('active');
})
$('.nav-pills .dropdown').on('show.bs.dropdown', function (e) {
$(this).siblings().find('.active').removeClass('active');
})

请记住：ID必须是唯一的(参考：myTab)

$('.nav-pills > a').on('show.bs.tab', function (e) {
$(this).siblings().removeClass('active');
})
$('.nav-pills .dropdown').on('show.bs.dropdown', function (e) {
$(this).siblings().find('.active').removeClass('active');
})

#v-pills-tab {
float: left;
display: inline-block;
width: 50%;
}
#v-pills-tabContent {
float: left;
display: inline-block;
width: 50%;
}
.container {
margin-top: 30px;
margin-bottom: 30px;
}
h2 {
margin: 15px 0;
}

看起来这在测试版中得到了解决：https://github.com/twbs/bootstrap/issues/23708#issuecomment-325263323
