我一直在尝试制作一个响应式导航栏，以在将来处理元素时用作模板。我遵循了一些教程并将我学到的东西混合在一起，现在当我尝试切换我创建的汉堡菜单时，我似乎无法切换它并且无法弄清楚我做错了什么。在这方面还是个新手，所以如果有人能指出我正确的方向，那就太好了。
这是我的 html 和 javascript:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Navigation</title>
<link rel="stylesheet" href="style.css">
<script src="script.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
</head>
<body>
<nav class="nav-main">
<img class="logo" src="images/melogo.png" alt="logo">
<span class="nav-button"> </span>
<ul class="nav">
<li>
<a href="#" class="nav-item">Home</a>
</li>
<li>
<a href="#" class="nav-item">Images</a>
</li>
<li>
<a href="#" class="nav-item">Spots</a>
<div class="nav-content">
<div class="nav-sub">
<ul>
<li><a href="#" class="nav-item">Street spots</a></li>
<li><a href="#" class="nav-item">Skateparks</a></li>
</ul>
</div>
</div>
</li>
<li>
<a href="#" class="nav-item">About us</a>
</li>
</ul>
</nav>
<script>
$('span.nav-button').click(function {
$('.nav-main ul').toggle();
})
</script>
<div class="content">
<p>
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

}
.nav-item{

-webkit-transition: max-height: 0.4s ease-in;
-moz-transition: max-height: 0.4s ease-in;
transition: max-height: 0.4s ease-in;
}
@media screen and (max-width: 600px){
.nav-main{
width: 100%;
background-color: #222;
min-height: 70px;
color: #fff;
display: block;
}
.nav-main > ul {
clear:both;
background-color: #222;
width: 100%;
}
.nav-main > ul > li{

}
.nav-item{
text-decoration: none;
width: 100%;
text-align: center;
}
.nav-button{
display: block;
background-color: #222;
color: red;

text-align: center;
cursor: pointer;
float: right;
padding-right: 30px;
}
.nav-button:before{
content: "H";
}
}
如有任何帮助，我们将不胜感激。
谢谢你们。
最佳答案
$('span.nav-button').click(function {
$('.nav-main ul').toggle();
});
到
$('span.nav-button').click(function() {
$('.nav-main ul').toggle();
});
你忘了在函数后面加上括号....
