ScrollTo:平滑滚动到页面指定位置

helloweba.com 作者:月光光 时间:2011年03月14日 12:13 标签: scroll  滚动  jQuery 

ScrollTo是一款基于jQuery的滚动插件,当点击页面的链接时,可以平滑地滚动到页面指定的位置。适用在一些页面内容比较多,页面长度有好几屏的场合,本文以DEMO为示例讲解该插件的应用。

使用方法

1、准备jQuery库和scrollTo.js插件。


<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/jquery.scrollTo.js"></script>

2、HTML


<ul class="nav">
   <li><a href="#" class="nav_pro">产品展示</a></li>
   <li><a href="#" class="nav_news">新闻中心</a></li>
   <li><a href="#" class="nav_ser">服务支持</a></li>
   <li><a href="#" class="nav_con">联系我们</a></li>
   <li><a href="#" class="nav_job">人才招聘</a></li>
</ul>
<div id="pro" class="box">
   <h3>产品展示</h3>
</div>
<div id="news" class="box">
   <h3>新闻中心</h3>
</div>
<div id="ser" class="box">
   <h3>服务支持</h3>
</div>
<div id="con" class="box">
   <h3>联系我们</h3>
</div>
<div id="job" class="box">
   <h3>人才招聘</h3>
</div>

我们用一个页面展示导航和导航对应的每个模块。

3、CSS


.nav{width:500px;margin:20px auto;}
.nav li{float:left; width:100px; height:24px; line-height:24px}
.box{height:500px}
.box h3{height:32px; line-height:32px; padding-left:20px; font-size:14px}
#pro,#ser{background:url(img/bg.jpg)}
#news,#con{background:url(img/bg2.gif)}

4、使用scrollTo.js插件


$(function(){
	$(".nav_pro").click(function(){
		$.scrollTo('#pro',500);
	});
	$(".nav_news").click(function(){
		$.scrollTo('#news',800);
	});
	$(".nav_ser").click(function(){
		$.scrollTo('#ser',1000);
	});
	$(".nav_con").click(function(){
		$.scrollTo('#con',1200);
	});
	$(".nav_job").click(function(){
		$.scrollTo('#job',1500);
	});
});

当点击导航按钮时,触发scrollTo方法,$.scrollTo带有两个参数,第一个是指定要滚动的目的ID,第二个参数是滚动时间间隔,以毫秒为单位。在本例中,只应用了scrollTo的基本方法。其实scrollTo还可以指定横向纵向滚动,传冲效果等,具体可以参照官方网站的例子:http://demos.flesler.com/jquery/scrollTo/

    $('html,body').animate({scrollTop: height}, 500); 一句话解决还要额外插件干嘛

    终于找到了!!!我的qq是1270449000,如果您愿意告知我答案!!
    你好,我最近遇到类似的问题,我在wordpress下了个主题,它可以通过导航菜单跳到指定位置,可以我自己用时发现不行,你能帮我看看哪里出问题了吗?我不太懂代码,不太会,这是我的网址www.miminiuniu.com

    function.php代码你能看看哪里出问题了吗
