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 |
