　　有时候，大家是不是因为写一些重复的代码而感到烦恼呢？由于在做ASP程序时，很多时候都要用到分页，重复作分页程序错误多不说了，而且影响到作程序的积极性，故写一分页函数，方便大家调用。如下：

'=================   ProgrammName: 分页函数   =======================
' ================   Programmed by Bubuy   =====================
'    ====================   2003.10.16   ========================
Function cutPage(sqlStr,Conn,dateNums,pageNums,URLs)'利用ADO分页的函数
Dim sql,Cn,dateNum,pageNum,URL,rsDate
Sql=Trim(sqlStr) '获得sql语句。
Set Cn=Conn '获得数据对象
dateNum=Cint(dateNums) '获得每页得记录数
pageNum=Cint(pageNums) '获得当前页码
URL=Trim(URLs) '获得路径
Set rsDate=Server.CreateObject("ADODB.Recordset")
rsDate.PageSize=dateNum
rsDate.Open Sql,cn,1,1
IF rsDate.Eof Then
     Response.Write("<center><font stlye='font-size:14px;' color='#ff0000'>对不起，没有记录！</font></center>")
Else
     IF pageNum="" or pageNum<1 Then
     pageNum=1
ElseIf pageNum>rsDate.PageCount Then
     pageNum=rsDate.PageCount
End IF
rsDate.absolutepage =pageNum
     Dim recordHead,recordLast '定义当前页开头记录和结束记录
recordHead=1
If pageNum>1 Then recordHead=dateNum*(pageNum-1)
If pageNum>=rsDate.PageCount Then
     recordLast=rsDate.RecordCount
     Else
     recordLast=dateNum*pageNum
End If
     Response.Write("<table width=100% border='0' cellpadding='0' cellspacing='0'
     Response.Write("<tr><td height=38 align=left><font stly='font-size:12px;'>（第"&recordHead&"-"&recordLast&"条，共"&rsDate.Recordcount&"条，每页显示"&dateNum&"条）</font></td></tr>")
Dim URLa '定义判断输入得URL包含?没有的变量
Dim upPage,downPage,allPage '定义向上和向下翻的变量
Dim allWrite '定义输出
upPage=pageNum-1
downPage=pageNum+1
     URLa=Split(URL,"?",-1,1)
     If URLa(0)=URL Then
     upPage="<a href=" & URL & "?page=" & upPage &" stlye='font-size:12px;'>上一页</a> "
  If pageNum=1 Then upPage=""
  downPage="<a href=" & URL & "?page=" & downPage &" stlye='font-size:12px;'>下一页</a>"
  If pageNum=rsDate.PageCount Then downPage=""
     Else
        upPage="<a href=" & URL & "&page=" & upPage &" stlye='font-size:12px;'>上一页</a> "
  If pageNum=1 Then upPage=""
  downPage="<a href=" & URL & "&page=" & downPage &" stlye='font-size:12px;'>下一页</a>"
  If pageNum=rsDate.PageCount Then downPage=""
     End If
allWrite=upPage & downPage & "  共" & rsDate.PageCount & "页 " & "目前第"& pageNum &"页"
allwrite="<font & allWrite & " 到第<input type='text' type='submit' value='GO'></font>"
Response.Write("<tr><form name='formPage' method='post' action="&URL&"><td height=30 align=right & allWrite & "</td></form></tr>")
Response.Write("<tr><td align=center>")
Response.Write("<table width=100% border='0' cellpadding='0' cellspacing='0' Response.Write("<tr>")
Response.Write("<tr bgcolor='#efffce' height=25>")
Dim id,i
For i=0 to rsDate.Fields.Count-1 '设置表头
     Response.Write("<td align='center'><font Next
Response.Write("</tr>")
id=0
While not rsDate.EOF and id<dateNum
     id=id+1
  If id Mod 2=0 then
           Response.Write("<tr bgcolor=#f7f6e7>")
        Else
           Response.Write("<tr bgcolor=#ffffff>")
        End If
  For Each fils in rsDate.Fields
        Response.Write("<td align='center' height=20>"&fils&"</td>")
  Next
  Response.Write("</tr>")
  rsDate.MoveNext
Wend
Response.Write("<tr height=25 bgcolor='#efffce'>")
     For i=0 to rsDate.Fields.Count-1 '设置表尾
     Response.Write("<td align='center'><font Next
Response.Write("</tr>")
Response.Write("</table></td></tr>")
Response.Write("<tr><form name='formPage1' method='post' action="&URL&"><td height=30 align=right>" & allWrite & "</td></form></tr>")
End IF
rsDate.close
Set rsDate=nothing
End Function
%>

这样使用
page=request("page")
sql="select * from [table]" '写sql语句
url="xx.asp"当然也可以是"xx.asp?bubuy=1"
conn大家都知道是定义的什么吧
调用就这样
Call cutPage(sql,conn,"3",page,url)'3代表每页显示3条记录
