javascript - Bootstrap 4 tab.js 事件状态卡住

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事件状态，并且在单击 way 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

起初我以为提供的代码片段中可能存在错误，但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 上测试

编辑:它在使用 Bootstrap 3.3.7 时有效:https://codepen.io/DannyJoris/pen/VzEZmw ，所以它一定是 Bootstrap 中的错误。

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');
})

记住:ID 必须是唯一的(引用: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;
}
