我们需要的功能:
1、调用该模块时,只需要传递记录集和每页显示的记录的条数;
2、可以点击链接进行翻页,也可以直接输入页码,回车后翻页;
3、不要考虑文件名,程序的每次翻页都能在当前页面。
具体编写内容

大家可以把翻页的链接做成图片按钮,这样的话也面就更加美观了。
调用方法:
1、在程序开始或要使用翻页的地方包含翻页模块文件;
2、定义变量:RowCount,每页显示的记录条数
3、调用翻页过程:Call TurnPage(记录集,RowCount)
4、在Do While 循环输出记录集的条件中加上" RowCount > 0 " 条件
5、在循环结束 "Loop前" 加上: RowCount = RowCount - 1
使用范例:
1.首先请将以上蓝框内代码转存为pagein.asp
2.我们使用DWMX2004新建一个ASP页面,内容如下
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%>
<!--#include file="Connections/conn.asp" -->
<!--#include file="pagein.asp"--> '引入公共翻页模块
<% '定义记录集
Dim rsnews
Dim rsnews_numRows
Set rsnews = Server.CreateObject("ADODB.Recordset")
rsnews.ActiveConnection = MM_conn_STRING
rsnews.Source = "SELECT * FROM dbo.zooNews WHERE nisshow = 1 ORDER BY naddtime DESC"
rsnews.CursorType = 1
rsnews.CursorLocation = 2
rsnews.LockType = 1
rsnews.Open()
rsnews_numRows = 0
%>
<% '使用重复行为(重复下面的<tr>标签内容)
Dim Repeat2__numRows
Dim Repeat2__index
Repeat2__numRows = 20
Repeat2__index = 0
rsnews_numRows = rsnews_numRows + Repeat2__numRows
%>
<html>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td height="40" align="right">
<% '关键在这里,在重复内容上面产生一个导航条
dim RowCount
RowCount = 20
call TurnPage(rsnews,RowCount)
%>
</td>
</tr>
<tr>

<table width="95%" border="0" align="center" cellpadding="0" cellspacing="0">
<tr>
<td height="1" valign="top" class="dotX"><img src="http://www.mbsky.com/infoview/images/spacer.gif" width="1" height="1"></td>
</tr>
<% '重复开始
While ((Repeat2__numRows <> 0) AND (NOT rsnews.EOF))
%>
<tr>
<td height="25"><% =(rsnews.Fields.Item("ntitle").Value) %>
<input type="submit" name="Submit" value="Submit">
</td>
</tr>
<%
Repeat2__index=Repeat2__index+1
Repeat2__numRows=Repeat2__numRows-1
rsnews.MoveNext()
Wend '重复结束
%>
<tr>
<td height="1" valign="top" class="dotX"><img src="http://www.mbsky.com/infoview/images/spacer.gif" width="1" height="1"></td>
</tr>
</table></td>
</tr>
<tr>
<td height="40" align="right">
<% '在重复内容下面产生一个导航条,可选,注意这里不再需要dim RowCount
RowCount = 20
call TurnPage(rsnews,RowCount)
%> </td>
</tr>
</table>
</body>
</html>
<% '关闭记录集
rsnews.Close()
Set rsnews = Nothing
%>
PS: 当用户输入不存在的页数时(如小数,负数等) 程序将自动过滤.
