Question

我正在使用Bootstrap建议的确切代码： -

<nav class="navbar navbar-default navbar-static-top">
    <div class="container">
        <div class="navbar-header">
            <button type="button" data-target="#navbarCollapse5" data-toggle="collapse" class="navbar-toggle">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a href="#" class="navbar-brand">Brand</a>
        </div>
        <div id="navbarCollapse5" class="collapse navbar-collapse">
            <ul class="nav navbar-nav">
                <li class="active"><a href="#">Home</a></li>
                <li><a href="#">Profile</a></li>
                <li><a href="#">Messages</a></li>
            </ul>
            <ul class="nav navbar-nav navbar-right">
                <li><a href="#">Login</a></li>
            </ul>
        </div>
    </div>
</nav>

这是JSFiddle。

请注意我在我的JSFiddle中使用了Bootstrap CSS和JS作为外部资源。

        <div class="navbar-header">
            <button type="button" data-target="#navbarCollapse" data-toggle="collapse" class="navbar-toggle">
                <span class="sr-only">Toggle navigation</span>

Answer 2

您需要使用v4 markup作为当前版本的bootstrap或使用v3 for your current markup

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

为什么这个引导程序导航不起作用？
