ASP高级类kktPage——将ASP查询分页封装起来（1）

0、前言：

这是04年编写的ASP类，实现了对查询分页、数据列表的封装，它与ASP模板类kktTemplate、数据库类clsDB是同一时期的作品，因此它需要数据库类以完成数据获取，支持模板类以完成内容的生成和输出。kktPage类集成了模板类和数据库类集成度很高，这主要源于作者在Win32程序编写方面的习惯，在当年很多人还诟病ASP的执行效率而裹步不前时，这种封装方式显得相当另类，也惹来不少非议，不知道在.Net流行的今天大家对它是什么看法。

ASP模板类kktTemplate请参阅http://blog.csdn.net/nhconch/archive/2004/07/10/38683.aspx

ASP数据库类请参阅http://blog.csdn.net/nhconch/archive/2004/07/16/42869.aspx

<!-- google_ad_client = "pub-5395599807454886"; /* 468x60, 创建于 09-4-19 */ google_ad_slot = "5917171131"; google_ad_width = 468; google_ad_height = 60; // -->

一、功能：

查询分页类有kktPage和kktPageEx，kktPageEx仅比kktPage多带了一个模板kktTemplate，其他并无差异，以下一并说明。

kktPage/kktPageEx目标就是完成的数据的分页列表显示，通过模板类和数据库类的集成，以最少的代码实现需要的功能，例如通过执行以下程序段：

Dim Page
Set Page = New kktPageEx
Page.SQL.SQLCommand = "select * from Orders"
Page.PageInfo.MaxList = 8
if Request.Form("page") <> "" then Page.PageInfo.Page = CInt(Request.Form("page"))
page.PageInfo.HtmlFormat = "第{FirstItem}-{LastItem}条信息，共{ItemsCount}条信息，第{Page}/{PageCount}页，当前页面显示{ListCount}条信息，设定最大显示条数为：{MaxList}.<br>"
Page.Template.Setup "pagetest.tpl", "TplHandle", "OrderList", "EmptyInfo"
Page.Template.Columns.Add "OrderID", "OrderID", "ID", 0, ""
Page.Template.Columns.Add "运输商", "ShipName", "Title", 20, ""
Page.Template.Columns.Add "下单日期", "OrderDate", "DateTime", 0, "DateValue"
Page.Process
Page.Display
Set Page = Nothing

并结合模板：

<form name="Form" method="post" action="PageExTest.asp">

<table width="400" border="1" bordercolor="#000000">

<tr><td><div align="center">kktPage类测试</div></td></tr>

<tr><td>我的订单</td> </tr>

<!-- google_ad_client = "pub-5395599807454886"; /* 728x90, 创建于 09-4-19 */ google_ad_slot = "3527615303"; google_ad_width = 728; google_ad_height = 90; // -->

<!-- BEGIN OrderList -->

<tr><td><a href="viewdetail.asp?id={ID}">{Title} [{DateTime}]</a></td></tr>

<!-- END OrderList -->

<!-- BEGIN EmptyInfo -->

<tr><td>Sorry，没有查询到数据。</td></tr>

<!-- END EmptyInfo -->

</table>

{PageInfo} ， {Buttons} {PageList}

</form>

便能得到以下结果：

kktPage类测试

我的订单

Toms Spezialitäten [1996-7-5]

Victuailles en stock [1996-7-8]

Ernst Handel [1996-7-17]

Ottilies Käseladen [1996-7-19]

Blondel père et fils [1996-7-25]

Frankenversand [1996-7-29]

White Clover Markets [1996-7-31]

Wartian Herkku [1996-8-1]

第1-8条信息，共830条信息，第1/104页，当前页面显示8条信息，设定最大显示条数为：8.
，[首页][上页][下页][未页]<!-- for (var i=1;i<=104;i++) if (i==1) document.writeln('<OPTION VALUE='+i+' selected>'+i); else document.writeln('<OPTION VALUE='+i+'>'+i); // -->1 2 3 4 5 …

二、实现代码：

kktPage/kktPageEx类被分成三个文件：

kktPageInc——分页查询对象支持模块，kktPage/kktPageEx所依赖的控件库；

kktPage——查询分页基础类，不带模板功能

kktPageEx——带模板的查询分页类

1、kktpageinc.asp
