用asp做一个分页程序
请看以下实现asp分页程序的代码：
$#@60;anguage="vbscript"
dim conn
dim connstr
dim totalput
dim currentpage
dim totalpages
dim i,j
dim sql
dim rs
on error resume next
打开数据库
connstr="dbq="+server.mappath("book.mdb")+";defaultdir=;driver={microsoft access driver (*.mdb)};"
set conn=server.createobject("adodb.connection")
conn.open connstr
set rs=server.createobject("adodb.recordset")
定义每页文章显示数
const maxperpage=18
if not isempty(request("page")) then
currentpage=cint(request("page"))
else
currentpage=1
end if
sql="select * from learning order by articleid desc"
set rs= server.createobject("adodb.recordset")
rs.open sql,conn,1,1
if rs.eof and rs.bof then
response.write "$#@60;p align=center$#@62; 还 没 有 任 何 文 章$#@60;/p$#@62;"
else
数据库中文章数totalput
totalput=rs.recordcount
if currentpage$#@60;1 then
currentpage=1
end if
统计总页数currentpage
if (currentpage-1)*maxperpage$#@62;totalput then
if (totalput mod maxperpage)=0 then
currentpage= totalput \ maxperpage
else
currentpage= totalput \ maxperpage + 1
end if
end if
if currentpage=1 then
showpage totalput,maxperpage,"index.asp"
showcontent
showpage totalput,maxperpage,"index.asp"
else
if (currentpage-1)*maxperpage$#@60;totalput then
rs.move (currentpage-1)*maxperpage
dim b mark
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
$#@62;
选择显示数据库内容
$#@60;a href="openarticle.asp?id=$#@60;=rs("articleid")$#@62;"$#@62;$#@60;=rs("title")$#@62;$#@60;/a$#@62;[点击：$#@60;=rs("hits")$#@62;]$#@60;br$#@62;
$#@60;
当显示记录大于maxperpage时结束这页
i=i+1
if i$#@62;=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 "$#@60;form method=post action="&filename&"$#@62;"
response.write "$#@60;p align=center$#@62;$#@60;font color=#000080$#@62;$#@62;$#@62;分页$#@60;/font$#@62; "
显示页数链接的条件
if currentpage$#@60;2 then
response.write "$#@60;font color=#000080$#@62;首页 上一页$#@60;/font$#@62; "
else
response.write "$#@60;a href="&filename&"?page=1&$#@62;首页$#@60;/a$#@62; "
response.write "$#@60;a href="&filename&"?page="¤tpage-1&"$#@62;上一页$#@60;/a$#@62; "
end if
if n-currentpage$#@60;1 then
response.write "$#@60;font color=#000080$#@62;下一页 尾页$#@60;/font$#@62;"
else
response.write "$#@60;a href="&filename&"?page="&(currentpage+1)
response.write "$#@62;下一页$#@60;/a$#@62; $#@60;a href="&filename&"?page="&n&"$#@62;尾页$#@60;/a$#@62;"
end ifc
response.write "$#@60;font color=#000080$#@62; 页次：$#@60;/font$#@62;$#@60;strong$#@62;$#@60;font color=red$#@62;"¤tpage&"$#@60;/font$#@62;$#@60;font color=#000080$#@62;/"&n&"$#@60;/strong$#@62;页$#@60;/font$#@62;"
response.write "$#@60;font color=#000080$#@62; 共$#@60;b$#@62;"&totalnumber&"$#@60;/b$#@62;篇文章 $#@60;b$#@62;"&maxperpage&"$#@60;/b$#@62;篇文章/页$#@60;/font$#@62;"
response.write " $#@60;font color=#000080$#@62;转到：$#@60;/font$#@62;$#@60;input type=text name=page size=4 maxlength=10 class=smallinput value="¤tpage&"$#@62;"
response.write "$#@60;input class=buttonface type=submit value= goto name=cndok$#@62;$#@60;/span$#@62;$#@60;/p$#@62;$#@60;/form$#@62;"
end function
$#@62;
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!
