本文实例讲述了jQuery实现的粘性滚动导航栏效果。分享给大家供大家参考，具体如下：
粘性滚动是当导航在滚动过程中会占粘于浏览器上，达到方便网站页面浏览的效果，也是一种用户体验，下面我们看一下是怎么实现的：
jQuery的 smint插件，也是一个导航菜单固定插件。当页滚动时，导航菜单会固定在顶部；当点击菜单时，页面会平滑的滚动到对应的区域。
兼容性
由于 smint 使用了 position: fixed，所以它不兼容 IE6。适用浏览器：IE8、360、FireFox、Chrome、Safari、Opera、傲游、搜狗、世界之窗.
引入文件
<link href="css/demo.css" rel="external nofollow" rel="stylesheet" type="text/css">
<script src="js/jquery.min.js"></script>
<script src="js/jquery.smint.js"></script>
HTML
<body onload="setTimeout(function() { window.scrollTo(0, 1) }, 100);">
<div class="wrap">
<div class="subMenu">
<div class="inner">
<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="sTop" class="subNavBtn">Home</a>
<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="s1" class="subNavBtn">Section 1</a>
<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="s2" class="subNavBtn">Section 2</a>
<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="s3" class="subNavBtn">Section 3</a>
<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="s4" class="subNavBtn">Section 4</a>
<a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" id="s5" class="subNavBtn end">Section 5</a>
</div>
</div>
<div class="section sTop">
<div class="inner"></div><br class="clear">
</div>
<div class="section s1">
<div class="inner"><h1>Section 1</h1></div>
</div>
<div class="section s2">
<div class="inner"><h1>Section 2</h1></div>
</div>
<div class="section s3">
<div class="inner"><h1>Section 3</h1></div>
</div>
<div class="section s4">
<div class="inner"><h1>Section 4</h1></div>
</div>
<div class="section s5">
<div class="inner"><h1>Section 5</h1></div>
</div>
</div>
</body>
注意：菜单的外部容器（如上例的 subMenu）需要设置样式 position:absolute，并且每个菜单的 a 标签需要设置 id，id 的值与下面对应区域的 class 的值一致。
JavaScript
$(function() {
$('.subMenu').smint({
scrollSpeed : 1000
});
});
