Question

我有一个导航标签的Bootstrap实现，加载页面时没有活动标签。但是，我想让每个标签的功能都作为一个切换工作，这样如果一个标签是＆＃34;活跃的＆＃34;它会丢失该类并默认为页面的原始状态。

这是我的HTML：

    <div class="well nav-base">
    <div class="pull-right"><a href="#">collapse all tabs</a></div>
    <ul class="nav nav-tabs" id="testtab">
        <li><a href="#home" data-toggle="tab">Home</a></li>
        <li><a href="#profile" data-toggle="tab">Profile</a></li>
        <li class="dropdown">
            <a href="#" id="myTabDrop1" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
            <ul class="dropdown-menu" role="menu" aria-labelledby="myTabDrop1">
                <li><a href="#dropdown1" tabindex="-1" data-toggle="tab">@fat</a></li>
                <li><a href="#dropdown2" tabindex="-1" data-toggle="tab">@mdo</a></li>
            </ul>
        </li>
    </ul>
    <div id="myTabContent" class="tab-content">
        <div class="tab-pane fade" id="home">

        </div>
    </div>
</div><!--/.well -->

这是jQuery：

$(function(){
    $("li.active a").click(function(){

        var $parent = $(this).parent();
        if (!$parent.hasClass("active")){
            $parent.addClass("active");
            event.stopImmediatePropagation();
        }
    });
});

我已经通过谷歌的深处搜索到了Bootstrap自己的网站，并且没有足够的结果。任何帮助表示赞赏。

我改变了你的JavaScript。基本上，您要做两件事：从选项卡按钮中删除.active类，并找到相应的选项卡内容并隐藏它。这就是我想出的：

$(function(){
    $(document).on("click", "li.active > a", function(){
        var $parent = $(this).parent();

        // Ensure link isn't just a dropdown menu link     
        if (!$parent.hasClass("dropdown")){
            // Deactivate tab buttons
            $("#testtab li").removeClass("active");

            // Hides tab contents
            tabName = $(this).attr("href");
            $(tabName).removeClass("active").addClass("fade");
        }
    });
});

我使用on()函数更改了回调函数的分配方式 - 使用click()不会考虑获得<li>的任何.active元素稍后将类应用于它们，只是那些目前拥有该类的类。

此外，在菜单中有一个下拉菜单，因此必须确保点击的链接不仅仅是下拉菜单链接，而且实际上是一个菜单项。我没有从.active只移除<li>类，而是发现有必要将其从导航菜单中的每个项目中删除，以确保下拉列表及其菜单项都已停用。

这里有JSFiddle来演示代码的实际效果。希望这可以帮助！如果您有任何问题，请告诉我。
