[英]Why doesn't my collapsible menu expand when I click on it?
不知道我的代碼中缺少什么。 當我縮小尺寸時，會顯示3條，但是當我單擊它們時，它們不會切換菜單。
<!DOCTYPE html>
<html>
<head>
<title>Prototype</title>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
</head>
<body>
<nav class="navbar navbar-default" role="navigation">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data- target="#main-nav">
<span class="sr-only">Toggle Navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a href="#" class="navbar-brand">Brand</a>
</div>
<!-- Collect nav links, forms, and other content into div for toggle -->
<div class="collapse navbar-collapse" id="main-nav">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Link</a></li>
<li><a href="#">Link</a></li>
<li><a href="#">Link</a></li>
<li><a href="#">Link</a></li>
</ul>
</div>
</div>
</nav>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
</body>
</html>
這是jsfiddle上的代碼： http : //jsfiddle.net/5SBqQ/
Bootstrap需要jQuery。 添加：
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
在添加引導程序之前，應先解決此問題。
