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,你就可以很简朴的实现对文章的治理了,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" 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 %> 返回类别: 教程 上一教程: 将ASP的DEBUG变得简朴的两个函数 下一教程: ASP UPLOAD 使用说明 您可以阅读与"用ASP做一个分页程序"相关的教程: · 一个简朴的ASP分页程序 · 一个简朴的ASP分页程序 · 比较方便的ASP分页程序 · 如何做一个高效的ASP数据库操作程序 · ASP万用分页程序 |
