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：
<anguage="vbscript"
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"
showContent
showpage totalput,MaxPerPage,"index.asp"
else
if (currentPage-1)*MaxPerPage<totalPut then
rs.move (currentPage-1)*MaxPerPage
dim bookmark
bookmark=rs.bookmark
showpage totalput,MaxPerPage,"index.asp"
showContent
showpage totalput,MaxPerPage,"index.asp"
else
currentPage=1
showpage totalput,MaxPerPage,"index.asp"
showContent
showpage totalput,MaxPerPage,"index.asp"
end if
end if
rs.close
end if
set rs=nothing
conn.close
set conn=nothing
sub showContent
dim i
i=0
do while not rs.eof
>
'选择显示数据库内容
<a href="openarticle.asp?id=<=rs("articleid")>"><=rs("title")></a>[点击：<=rs("hits")>]<br>
<
'当显示记录大于maxperpage时结束这页
i=i+1
if i>=MaxPerPage then exit do
rs.movenext
loop
end sub
function showpage(totalnumber,maxperpage,filename)
'求出当每页18篇文章时总共的页数
dim n
if totalnumber mod maxperpage=0 then
n= totalnumber \ maxperpage
else
n= totalnumber \ maxperpage+1
end if
response.write "<form method=Post action="&filename&">"
response.write "<p align='center'><font color='#000080'>>>分页</font> "
'显示页数链接的条件
if CurrentPage<2 then
response.write "<font color='#000080'>首页 上一页</font> "
else
response.write "<a href="&filename&"?page=1&>首页</a> "
response.write "<a href="&filename&"?page="&CurrentPage-1&">上一页</a> "
end if
if n-currentpage<1 then
response.write "<font color='#000080'>下一页 尾页</font>"
else
response.write "<a href="&filename&"?page="&(CurrentPage+1)
response.write ">下一页</a> <a href="&filename&"?page="&n&">尾页</a>"
end ifc
response.write "<font color='#000080'> 页次：</font><strong><font color=red>"&CurrentPage&"</font><font color='#000080'>/"&n&"</strong>页</font>"
response.write "<font color='#000080'> 共<b>"&totalnumber&"</b>篇文章 <b>"&maxperpage&"</b>篇文章/页</font>"
response.write " <font color='#000080'>转到：</font><input type='text' name='page' size=4 maxlength=10 class=smallInput value="¤tpage&">"
response.write "<input class=buttonface type='submit' value=' Goto ' name='cndok'></span></p></form>"
end function

以上代码很简单的就实现了ASP网页的多种分页功能,不论是对浏览者还是管理者都能很方便的浏览和管理,我只在相关部分作了一些解释,象这个ASP程序还必须有数据库的支持才可以,关于数据库的问题我就不详述了,具体的实例大家可以看看我的主页(http://aasp.yeah.net)上的文章管理程序,另外还有具体的程序下载!
