Question

我是HTML，CSS和Javascript的新手。我有一个导航栏，当在移动设备中显示时会显示一个按钮导航栏切换器。我需要一些关于onClick的Javascript的帮助，因为我以前从未做过，而且在Bootstraps网页上没有关于它的真实文档。

以下是移动设备上的内容：

这是我的代码：

<body>
    <nav class="navbar navbar-expand-lg navbar-dark bg-dark">
        <a class="navbar-brand" href="index.html" id="movielogo"><img src="moviefylogo.png" height="35px"></a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor02" aria-controls="navbarColor02"
            aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>

        <div class="collapse navbar-collapse" id="navbarColor02">
            <ul class="navbar-nav mr-auto">
                <li class="nav-item active">
                    <a class="nav-link" href="index.html">Home
                        <span class="sr-only">(current)</span>
                    </a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="library.html">Library</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="uploads.html">Uploads</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="about.html">About</a>
                </li>
            </ul>
        </div>
    </nav>
</body>

确保在HTML文件中包含Jquery和Bootstrap CDN（CSS和JS）它工作正常，检查我的jsfiddle链接：https://jsfiddle.net/u52vw4vs/1/

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
    <a class="navbar-brand" href="index.html" id="movielogo"><img src="moviefylogo.png" height="35px"></a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarColor02" aria-controls="navbarColor02"
        aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarColor02">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="index.html">Home
                    <span class="sr-only">(current)</span>
                </a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="library.html">Library</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="uploads.html">Uploads</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="about.html">About</a>
            </li>
        </ul>
    </div>
</nav>

我只是复制粘贴你的代码，检查左侧菜单中的“资源”，我添加了Bootstrap 4 CDN文件。

亲切的问候。
