Bootstrap响应式前端框架笔记十八——导航滚动监听

Bootstrap框架中提供了十分方便的方法来使用导航关联内容快，而且开发者能够监听滚动进行导航按钮的切换，示例以下：javascript

<!DOCTYPE html>
<html>

	<head>
		<meta charset="UTF-8">
		<link rel="stylesheet" href="../bower_components/bootstrap/dist/css/bootstrap.css" />
		<script type="text/javascript" src="../bower_components/jquery/dist/jquery.js"></script>
		<script type="text/javascript" src="../bower_components/bootstrap/dist/js/bootstrap.js"></script>
		<style>
			.scrollspy-example {
				position: relative;
				height: 200px;
				margin-top: 10px;
				overflow: auto
			}
		</style>
		<title>滚动监听</title>
	</head>

	<body class="container">
		<br />
		<br />
		<!--导航栏-->
		<nav id="navbar" class="navbar navbar-default navbar-static">
			<div class="navbar-header">
				<button class="navbar-toggle" type="button" data-toggle="collapse" data-target=".navigationShow">
					<span class="icon-bar"></span>
            			<span class="icon-bar"></span>
            			<span class="icon-bar"></span>
				</button>
				<a class="navbar-brand" href="#">列表</a>
			</div>
			<!--导航容器-->
			<div class="navbar-collapse navigationShow">
				<!--导航-->
				<ul class="nav navbar-nav">
					<li class="active">
						<a href="#One">第一项</a>
					</li>
					<li class="">
						<a href="#Two">第二项</a>
					</li>
					<li class="dropdown">
						<a href="#" id="navbarDrop1" class="dropdown-toggle" data-toggle="dropdown">菜单 <span class="caret"></span></a>
						<ul class="dropdown-menu">
							<li class="">
								<a href="#one">菜单1</a>
							</li>
							<li class="">
								<a href="#two">菜单2</a>
							</li>
							<li class="divider"></li>
							<li class="">
								<a href="#three">菜单3</a>
							</li>
						</ul>
					</li>
				</ul>
			</div>
		</nav>
		<!--内容div 使用data-spy="scroll"来进行滚动监听-->
		<div data-spy="scroll" data-target="#navbar" class="scrollspy-example">
			<!--id须要对应-->

效果以下所示：css

开发者也能够对导航标签的切换事件进行监听，方法以下：html

$('#navbar').on('activate.bs.scrollspy',function(e){
		console.log("滚动导航改变");
})
