摘要：最简化分页程序，附源代码

pagetest.asp 表现页面



<%

strSql = "select * from authors"

set rs=server.CreateObject("ADODB.RecordSet")

rs.open strSql,conn,1,1

set page = new PageBase

page.pagesize = 3

if not isnumeric(request("page")) then
page.currentpage=1
else
if (cint(request("page")<1)) then
page.currentpage=1
else
page.currentpage=request("page")
end if
end if

page.linkurl="pagetest.asp"

page.show(rs)

page.FenYe(rs)
%>
