我已经在 codepen 中看到此代码作为示例,因此我尝试将其复制到我在 phpstorm 中的项目中。我运行代码,但侧边栏没有向我打开,我不明白为什么。这是代码:

<!DOCTYPE html>
<html>
<head>
    <link rel = "stylesheet" type="text/css" href = "Sources/bootstrap.css">
    <link rel = "stylesheet" type="text/css" href = "Sources/MatirialIcons.css">
    <link rel = "stylesheet" type="text/css" href = "Sources/Matirialize.css">
    <script type = "text/javascript"
            src = "Sources/jquery-2.1.1.js"></script>
    <script src = "Sources/Matirialize.js"></script>
    <meta name="viewport" content="width=device-width, initial-scale=1">


</head>
<style>
    body {
        font-family: "Lato", sans-serif;
    }

    .sidenav {
        height: 100%;
        width: 250px;
        position: fixed;
        z-index: 1;
        top: 0;
        left: 0;
        background-color: #111;
        overflow-x: hidden;
        transition: 0.5s;
        transform: translateX(-100%);
        padding-top: 60px;
    }

    .sidenav a {
        padding: 8px 8px 8px 32px;
        text-decoration: none;
        font-size: 25px;
        color: #818181;
        display: block;
        transition: 0.3s;
    }

    .sidenav a:hover {
        color: #f1f1f1;
    }

    .sidenav .closebtn {
        position: absolute;
        top: 0;
        right: 25px;
        font-size: 36px;
        margin-left: 50px;
    }
    .open-bg {
        background-color: rgba(0,0,0,0.4);
        overflow: hidden;
    }
    .open {
        transform: translateX(0px);
    }
    @media screen and (max-height: 450px) {
        .sidenav {padding-top: 15px;}
        .sidenav a {font-size: 18px;}
    }
</style>
<body>
<div class="container">
    <div id="mySidenav" class="sidenav">
        <a href="javascript:void(0)" class="closebtn" id="closeNav">&times;</a>
        <a href="#">About</a>
        <a href="#">Services</a>
        <a href="#">Clients</a>
        <a href="#">Contact</a>
    </div>
    <span style="font-size:30px;cursor:pointer" id="openNav">&#9776; Brand</span>
</div>
</body>

<script>
    $( "#openNav" ).click(function() {
        $('#mySidenav').addClass('open');
        $('body').addClass('open-bg');
    });
    $( "#closeNav" ).click(function() {
        $('#mySidenav').removeClass('open');
        $('body').removeClass('open-bg');
    });

</script>
</html>

为什么侧边栏打不开?这是我从中复制的 codepen 代码的链接: https ://codepen.io/shantikumarsingh/pen/gXPjdG

它在那里完美运行,我需要一个与示例中完全相同的侧边栏。

我复制/粘贴了您的代码并将 jQuery 调用更改为以下代码:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

这对我来说似乎很好,所以我的猜测是你的 jQuery 调用不起作用(错误的目录、文件名输入错误等),所以一旦你修复了一切都应该正常工作。

希望这可以帮助!
