关于一个ASP 分页系统的问题！

wcnjy 2009-08-24 05:20:05
这是我在网上下的一个ASP 分页系统，但是使用后发现一个问题，当数据记录为空时，读取便会出错：

错误类型：
ADODB.Recordset (0x800A0BCD)
BOF 或 EOF 中有一个是“真”，或者当前的记录已被删除，所需的操作要求一个当前的记录。
/浙江昌达食品调味网/浙江昌达/inc/page_class.asp, 第 104 行

以下是 分页代码 -----page_class.asp------

哪用那么麻烦。。。。。。。
还不如用这个代码


  Sub Pagination_Init(objRS, Page_Size) '数据分页模块

    objRS.PageSize = Page_Size

    Page = Trim(Request.QueryString("Page"))

    If Not (IsNumeric(Page)) Then Page = 1

    If Int(Page) > Int(objRS.PageCount) Or Int(Page) < 1 Then

      Page = 1

    Else

     Page = Int(Page)

    End If

    objRS.AbsolutePage = Page

End Sub



Function Pagination(objRS, PageUrl, intFCount) '数据分页模块

   Response.Write "<form name='form' method='post' action=url>"

   If PageUrl <> "" Then

     PageUrl = PageUrl & "&"

   Else

     PageUrl = "?"

   End If

  If Page <= 1 Then

   Response.Write "[首页][上一页] "

  Else

   Response.Write "[<a href='" & PageUrl & "Page=1'>首页</a> ]"

   Response.Write "[<a href='" & PageUrl & "Page=" & (Page - 1) & "'>上一页</a>]"

  End If

  If Page >= objRS.PageCount Then

    Response.Write "[下一页][尾页]"

  Else

    Response.Write "[<a href='" & PageUrl & "Page=" & (Page + 1) & "'>下一页</a>]"

    Response.Write "[<a href='" & PageUrl & "Page=" & objRS.PageCount & "'>尾页</a>]"

  End If

   Response.Write "转到：<select name='Page' size='1' onchange=""javascript:window.location='" & PageUrl & "Page=" & "'+this.options[this.selectedIndex].value;"">"

  For i = 1 To objRS.PageCount

  If i = Page Then

   Response.Write "<option selected value=" & i & ">" & "第" & i & "页" & "</option>"

  Else

   Response.Write "<option value=" & i & ">" & "第" & i & "页" & "</option>"

  End If

  Next

  Response.Write "</select>"

  Response.Write "[共<Font color='Red'><b>" & objRS.RecordCount & "</b></Font>条记录]"

  Response.Write "[页次<Font color='Red'>" & Page & "</Font>/" & objRS.PageCount & "页]"

  End Function



调用：
rs.Open sqlt, conn, 1, 1
Call Pagination_Init(rs, Page_Size)
intRecCount = 0
intFCount = rs.Fields.Count - 1

Do While Not rs.EOF And intRecCount < rs.PageSize


'response.write rs...



rs.MoveNext
intRecCount = intRecCount + 1
s = s + 1
Loop

Call Pagination(rs, req, intFCount)
