方法一：<script type="text/javascript">
var cUrl=location.href;
function writePage(url){
var parttern=/\/(\d+)\.html$/; //定义匹配字符串
var urlArr;
if(urlArr=url.match(parttern)) //urlArr[1]为取得的数字
{
pNum=parseInt(urlArr[1])+1;
pNext=url.replace(parttern,"/"+pNum+".html");
nNum=parseInt(urlArr[1])-1;
pPerv=url.replace(parttern,"/"+nNum+".html");
document.write("<a href=\""+pPerv+"\">上一页</a> <a href=\""+pNext+"\">下一页</a>");
}
else
{
document.write("当前没有分页!");
}
}
writePage(cUrl);
</script> <html>
<head><title>6</title>
<script language="javascript">
方法二：
</script></head>
<body>
<h1>这是6.html</h1>
<input type="button" value="上一页" onclick="forward()"><br>
<input type="button" value="下一页" onclick="back()">

分页可以用PageDataSource或存诸过程分页，上面是存诸过程
分页主要是有记录好页面索引可以用ViewState来存诸索引值，防止页面更新数据丢失.
