Question

有人可以向我解释为什么这不起作用吗？当我点击汉堡包菜单时没有任何反应。我尝试过包含各种bootstrap js和css文件但没有修复它。

这是我的代码。 JSFiddle

<nav class="navbar navbar-default" role="navigation">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#">Blog</a>
        </div>
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav">
            <li class="active"><a href="#">Home</a></li>
            <li><a href="#">Archive</a></li>
            <li><a href="#">About</a></li>
            <li><a href="#">Contact</a></li>
            </ul>
        </div>
    </div>
</nav>

您忘记添加jquery而没有哪个下拉列表不起作用。

正常工作
