先将分页类源代码发上来，随后有空会发一些实例来讲解其用法，以及如何扩展其功能。

类原代码如下：

\'==============================================
\'XDOWNPAGE ASP版本
\'当前版本：2.0
\'
\'
\'原版本 1.00

\'升级说明：
\'
\'
\'升级版本：2.0 \' (asp + oracle) ---->当前版本
\'保留原名：XDOWNPAGE

\'升级说明：
\'1 , 数据查询时只查询当前页所包含的记录，大大降低了数据传输量
\'2 , 如果正常的页导航，不用每次都查询总记录数，只要第一次查询后，后来通过参数传递即可
\'3 , 支持动态更改页大小
\'4 , 支持动态排序
\'5 , 本程序只支持oracle,如果想用在sqlserver或者其他类型的数据库，请自行修改：Public Property Let GetSQL(str_sql)即可。
\'

\'
\'
\'程序特点
\'本程序主要是对数据分页的部分进行了封装，而数据显示部份完全由用户自定义，
\'支持URL多个参数
\'
\'使用说明
\'程序参数说明
\'PapgeSize 定义分页每一页的记录数
\'GetRS 返回经过分页的Recordset此属性只读
\'GetConn 得到数据库连接
\'GetSQL 得到查询语句
\'totalRecordCount 传递总记录数

\'程序方法说明
\'ShowPage 显示分页导航条,唯一的公用方法
\'ShowPageSizeChange() 显示改变页大小的列表
\'
\'例:
\'
\' \'包含文件
\'
\' Set mypage=new xdownpage \'创建对象
\' mypage.getconn=conn \'得到数据库连接
\' mypage.getsql="select * from productinfo order by id asc"
\' mypage.pagesize=5 \'设置每一页的记录条数据为5条
\'mypage.totalRecordCount=rsTotalCount 设置总记录数
\' set rs=mypage.getrs() \'返回Recordset
\'mypage.GetSubmitForm="frmQuery" \' 分页默认提交的表单，currentpage参数
\'Response.write(mypage.GetSubmitForm1()) \'输出分页提交的函数
\' mypage.showpage() \'显示分页信息，这个方法可以，在set rs=mypage.getrs()以后
\' 任意位置调用，可以调用多次
\' do while not rs.eof \'接下来的操作就和操作一个普通Recordset对象一样操作
\' response.write rs(0) & "
\' " \'这里就可以自定义显示方式了
\' rs.movenext
\' loop
\'
\'添加了保存当前页面数量的提交脚本
\'函数为GetSubmitForm()
\'需要提交给函数GetSubmitForm一个表单名字
\'在这个提交的表单里面保存变量flag,currentpage,pagesize,rsTotalCount 四个参数
\'例子如下
\'flag=request("flag")
\'currentpage=request("currentpage")
\'currentpage=request("pagesize")
\'currentpage=request("rsTotalCount")
\'在提交的表单里面加入下面四个input
\'<input name="flag" type="hidden" value="< % =flag% >">
\'<input name="currentpage" type="hidden" value="< % =currentpage% >">
\'<input name="pagesize" type="hidden" value="< % =pagesize% >">
\'<input name="rsTotalCount" type="hidden" value="< % =rsTotalCount% >">
\'==============================================

Const Btn_First="<font face=""webdings"">9</font>" \'定义第一页按钮显示样式
Const Btn_Prev="<font face=""webdings"">3</font>" \'定义前一页按钮显示样式
Const Btn_Next="<font face=""webdings"">4</font>" \'定义下一页按钮显示样式
Const Btn_Last="<font face=""webdings"">:</font>" \'定义最后一页按钮显示样式
Const XD_Align="center" \'定义分页信息对齐方式
Const XD_Width="100%" \'定义分页信息框大小
Const XD_Height="20"
