用ASP做一个分页程序
类别: ASP教程 
你是否为了你的站点文章过多而反复做链接上一页、下一页这些烦琐的工作发愁呢？现在有了ASP，只要你的主页支持ASP，你就可以很简单的实现对文章的管理了，排序、链接、显示这些工作都让ASP去完成吧！这么轻松的主页维护，你是不是也想试一试呢？
请看以下实现ASP分页程序的代码：
<%
dim conn
dim connstr
dim totalPut
dim CurrentPage
dim TotalPages
dim i,j
dim sql
dim rs
on error resume next
\'打开数据库
connstr="DBQ="+server.mappath("book.mdb")+";DefaultDir=;DRIVER={Microsoft Access Driver (*.mdb)};"
set conn=server.createobject("ADODB.CONNECTION")
conn.open connstr
set rs=server.createobject("adodb.recordset")
\'定义每页文章显示数
const MaxPerPage=18
if not isempty(request("page")) then
currentPage=cint(request("page"))
else
currentPage=1
end if
sql="select * from learning order by articleid desc"
Set rs= Server.CreateObject("ADODB.Recordset")
rs.open sql,conn,1,1
if rs.eof and rs.bof then
response.write "<p align=\'center\'> 还 没 有 任 何 文 章</p>"
else
\'数据库中文章数totalput
totalPut=rs.recordcount
if currentpage<1 then
currentpage=1
end if
\'统计总页数currentpage
if (currentpage-1)*MaxPerPage>totalput then
if (totalPut mod MaxPerPage)=0 then
currentpage= totalPut MaxPerPage
else
currentpage= totalPut MaxPerPage + 1
end if
end if
if currentPage=1 then
showpage totalput,MaxPerPage,"index.asp"
