html - 为什么我的导航切换按钮不起作用？

问题描述

为什么我在手机或小屏幕上的导航切换按钮不起作用？我使用引导程序，找不到我的错误。我的导航栏应该是响应式的。

<nav class="navbar navbar-expand-sm navbar-light bg-light">
<button
        type="button"
        data-bs-toggle="collapse"
        data-bs-target="#navbarNav"
        class="navbar-toggler"
        aria-controls="navbarNav"
        aria-expanded="false"
        aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav">
        <li class="nav-item active">
            <a class="nav-link active" href="dashboard.php">Dashboard</a>
        </li>
        <li class="nav-item">
            <a class="nav-link" href="shareOverview.php">Verwaltung</a>
        </li>
        <li class="nav-item active">
            <a class="nav-link" href="addShare.php">Neue Aktie</a>
        </li>
        <?php
        if (isset($_SESSION['name'])) {
            ?>
            <li class="nav-item active">
                <a class="nav-link" href="logout.php">Logout</a>
            </li>
            <?php
        }
        ?>
    </ul>
</div>
</nav>

解决方案

您使用的是 Bootstrap 4 还是 Bootstrap 5？它data-toggle代替data-bs-toggle了 Bootstrap 4。
