我想在我的 html 文件中使用 .js 脚本，但不幸的是我的脚本无法以正确的方式工作:(。我为我的网站构建了一个响应式导航栏，在小屏幕上有一个"汉堡菜单"。 我设法在较小的屏幕上显示"汉堡菜单"，但是如果我单击它，我的导航栏链接不会显示。这是我的 html 代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width", "initial-scale=1">
<link rel="stylesheet" href="css/style.css">
<script src="script/script.js"></script>
<title>Title</title>
</head>
<header>
<nav class="navbar">
<div class="branding">
<a href="index.html"><img src="img/Logo.png" alt="Brand"></a>
</div>
<a href="#" class="toggle-button">
<span class="bar"></span>
<span class="bar"></span>
<span class="bar"></span>
</a>
<div class="navbar-links">
<ul>
<li><a href="index.html">Home</a></li>
<li><a href="artikel.html">Artikel</a></li>
<li><a href="shop.html">Shop</a></li>
<li><a href="handel.html">handel</a></li>
<li><a href="kontakt.html">Kontakt</a></li>
</ul>
</div>
</nav>
</header>
</body>
</html>
这是我的 CSS：
body{
margin: 0;
padding: 0;
font-family: sans-serif;
}
header{
background-color: white;
padding-top: 10px;
min-height: 70px;
border-bottom: black 3px solid;
align-items: center;
}
.navbar{
width: 80%;
margin: auto;
overflow: hidden;
align-items: center;
}
.branding{
float: left;
margin: 0;
padding: 0;
}
.navbar-links{
margin-top: 25px;
padding: 0;
float: right;
}
.navbar-links ul{
margin: 0;
padding: 0;
display: flex;
list-style: none;
}
.navbar-links ul li a{
padding: 25px;
color: black;
text-decoration: none;
text-transform: uppercase;
font-size: 18px;
font-weight: 500;
}
.navbar-links a:hover{
color: #ffbf00;
}
.toggle-button{
margin-top: 20px;
position: absolute;
top: .75rem;
right: 1rem;
display: none;
flex-direction: column;
justify-content: space-between;
width: 30px;
height: 21px;
}
.toggle-button .bar{
height: 3px;
width: 100%;
color: black;
background-color: black;
border-radius: 10px;
}
@media (max-width: 1050px) {
.toggle-button{
display: flex;
}
.navbar-links{
display: none;
width: 100%;
}
.navbar{
flex-direction: column;
align-items: flex-start;
}
.navbar-links ul{
width: 100%;
flex-direction: column;
}
.navbar-links li{
text-align: center;
}
.navbar-links li a{
padding: .5rem 1rem;
}
.navbar-links.active{
display: flex;
}
}
我想重要的部分是我的JavaScript：
const toggleButton = document.getElementsByClassName('toggleButton')[0]
const navbarLinks = document.getElementsByClassName('navbar-links')[0]
toggleButton.addEventListener('click', () => {
navbarLinks.classList.toggle('active')
})
为很多代码感到高兴，但我想在您的帮助下找到错误，所以我发布了我的所有代码。谢谢
它将toggle-button不toggleButton
const toggleButton = document.getElementsByClassName('toggle-button')[0];
const toggleButton = document.getElementsByClassName('toggle-button')[0];
const navbarLinks = document.getElementsByClassName('navbar-links')[0];
console.log(toggleButton);
toggleButton.addEventListener('click', () => {
navbarLinks.classList.toggle('active')
})body{
