具体代码如下
<html> <head> <title>jQuery平滑滚动的标签分栏切换</title> <meta charset="gb2312"> <style> ul,li{ margin:0px; padding:0px; list-style:none } li{ float:left; background-color:#8c6239; color:white; padding:5px; margin-right:2px; border:1px solid white; } li.myLi{ background-color:#ea5500; border:1px solid #ea5500; } div{ clear:left; background-color:#ea5500; color:white; width:300px; height:100px; padding:10px; display:none; } div.myDiv{ display:block; } </style> <script src="https://www.jb51.net/article/jquery-1.7.1.min.js"></script> <script> var timeId; $(document).ready(function(){ $("li").each(function(index){ //index是li数组的的索引值 $(this).mouseover(function(){ var liNode = $(this); //延迟是为了减少服务器压力，防止鼠标快速滑动 timeId = setTimeout(function(){ //将原来显示的div隐藏掉 $("div.myDiv").removeClass("myDiv"); //将原来的li的myLi去掉 $("li.myLi").removeClass("myLi"); //显示当前鼠标li的对应的div $("div").eq(index).addClass("myDiv"); //增加当前li的myLi liNode.addClass("myLi"); },300); }).mouseout(function(){ clearTimeout(timeId); }); }); }); </script> </head> <body> <ul> <li>this is li 1</li> <li>this is li 2</li> <li>this is li 3</li> </ul> <div>this is div1</div> <div>this is div2</div> <div>this is div3</div> </body> </html>
