Question

我的汉堡菜单有问题。我单击它，它会打开菜单，但是当我再次单击它时，它不会关闭菜单。它似乎在闪烁，因此可能已关闭并在单击时重新打开。导致汉堡菜单无法关闭的以下代码有什么问题？

<section id="nav-bar">

    <nav class="navbar navbar-expand-lg navbar-light">
        <a class="navbar-brand" href="/../#"><img src="../img/logo.png"></a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" 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 ml-auto">
                <li class="nav-item">
                    <a class="nav-link" href="/../#top">HOME</a>
                </li>
