html5页面，代码如下，该引用的文件也引用了，点击下拉菜单就是没有反应

Code:

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<meta http-equiv="X-UA-Compatible" content="IE=edge">
	<meta name="viewport" content="width=device-width, initial-scale=1">
	<title>Bootstrap</title>
	<link rel="stylesheet" href="css/bootstrap.min.css">
	<style>
		.a {
			height: 50px;
			border: 1px solid #ccc;
			background-color: #eee;
		}
		body {
			margin: 50px;
		}
	</style>
</head>
<body>
 <div class="dropdown">
 	<button class="btn btn-default" data-toggle="dropdown">
 		下拉菜单
 		<span class="caret"></span>
 	</button>
	<ul class="dropdown-menu">
		<li><a href="#">a</a></li>
		<li><a href="#">b</a></li>
		<li><a href="#">c</a></li>
		<li><a href="#">d</a></li>
	</ul>
 </div>

 	<script src="js/bootstrap.min.js"></script>
	<script src="js/jquery-1.12.4.min.js"></script>
</body>
</html>

问题简单，把 jquery.min.js 的引用挪到 bootstrap.min.js 前面去，就行了；
即：

Code:

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<meta http-equiv="X-UA-Compatible" content="IE=edge">
	<meta name="viewport" content="width=device-width, initial-scale=1">
	<title>Bootstrap</title>
	<link rel="stylesheet" href="css/bootstrap.min.css">
	<style>
		.a {
			height: 50px;
			border: 1px solid #ccc;
			background-color: #eee;
		}
		body {
			margin: 50px;
		}
	</style>
</head>
<body>
 <div class="dropdown">
 	<button class="btn btn-default" data-toggle="dropdown">
 		下拉菜单
 		<span class="caret"></span>
 	</button>
	<ul class="dropdown-menu">
		<li><a href="#">a</a></li>
		<li><a href="#">b</a></li>
		<li><a href="#">c</a></li>
		<li><a href="#">d</a></li>
	</ul>
 </div>

 
	<script src="js/jquery-1.12.4.min.js"></script>
	<script src="js/bootstrap.min.js"></script>
</body>
</html>
