Question

我在引导程序4中修改导航，构建而不是模板化，并且出于某种原因，我的下拉列表无法正常工作。我点击它们，然后他们带我到我插入的任何网站，而不是向我显示选择的选项。就此而言，汉堡包的切换器也不起作用。有什么想法吗？

    <nav class="navbar fixed-top navbar-toggleable-md navbar-inverse" style="background-color: #0E0B16;">
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="home.html">EX</a>
        <div class="collapse navbar-collapse" id="navbarsExampleDefault">
            <ul class="navbar-nav mr-auto">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="bio.html">Bio</a>
                </li>
                <li class="nav-item dropdown">
                    <a class="nav-link dropdown-toggle" href="#" role="button" id="dropdownPortfolio" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                        Portfolio
                    </a>
                    <div class="dropdown-menu" aria-labelledby="dropdownPortfolio">
                        <a class="dropdown-item" href="filmportfolio.html">Film</a>
                        <a class="dropdown-item" href="stageportfolio.html">Stage</a>
                        <a class="dropdown-item" href="beautyportfolio.html">Beauty</a>
                    </div>
                </li>
            </ul>
            <ul class="nav navbar-nav navbar-sub pull-right">
                <li class = "navbar-text"><i class="fa fa-phone" aria-hidden="true"></i> 555-555-5555</li>
                <li class= "navbar-text"><i class="fa fa-envelope-o" aria-hidden="true"></i> ex@example.com</li>
            </ul>
        </div>
    </nav>

没有看到整个页面代码，这只是一个有根据的猜测，但是，听起来你遗漏了jquery和/或bootstrap.js / bootstrap.min.js。汉堡包的展示/折叠和下拉菜单取决于.js文件。

Bootstrap 4 alpha，导航中的下拉菜单不起作用
