摘要：创建一个ASP通用分页类

从开始学习到使用ASP到现在也写了不少程序了，最令人头痛的是写数据分页，每次都是由于几个变量名或几个参数的不同，因而需要每次都写哪一段冗长而又繁杂的分页代码，代码长了使得程序的可读性变差，容易出差，调试半天也找不出错在哪里，所以慢慢的我开始使用一些网上的提供的分页函数或分页类。的确省事不少，但是通常的函数和类的做法都是就数据显示部分也封装了起来，每次为了达到自己需要的显求效果要去改动函数或者类的本身，所以使用起来也不是怎么方便,自己写的分页改起来已经够复杂了，更不要说别人的了。所以趁昨天有空自己写了一个分页的类，自我感觉良好（不要用鸡蛋砸我），在这里和大家分享一下自己的经验（谈不上经验，感想吧）。在这里我也不想说分页的原理了，反正大家都懂，要我往深入的谈我也不会。呵呵。 [b]一、创建分页类的目标 [/b]在写之前，我曾想过，我究竟要写怎么样一个类，回想起以前写分页过程的时候，最烦的莫过于每次都要写哪一段复杂的分页代码，最大的烦恼每次都是仅仅几个变量名的不同。所以第一个要实现的就是要把这个封装起来，第二个就是要把分页的导航条也封装起来,第三个，不习惯哪些把数据显示部分也封装起来的方法，这不是方便编程，对与哪些对显示效果每次都不同的用户来说，比自己写分页还要麻烦。所以我的目地就是对RecordSet进行一些简单的封装。 [b]二、创建过程[/b] 所以我写的第一个属性，就是返一个经过处理的RecordSe

[img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Public Property Get GetRs() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Set XD_Rs=Server.createobject("adodb.recordset") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] XD_Rs.PageSize=PageSize [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] XD_Rs.Open XD_SQL,XD_Conn,1,1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If not(XD_Rs.eof and XD_RS.BOF) Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If int_curpage>XD_RS.PageCount Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_curpage=XD_RS.PageCount [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] XD_Rs.AbsolutePage=int_curpage [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Set GetRs=XD_RS [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Property

这个属性的作用是更据指定RecordSet 的当前面，并到指针指向当前页的第一条记录,这个应该就是整个类的完成分页的核心了，当然，其中的一些参数是靠其它的属性来获取，所以这里顺便介绍一个这个类所要的基本参数

[img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] ============================================= [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] 'GetConn 得到数据库连接 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] ' [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '============================================= [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Public Property Let GetConn(obj_Conn) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Set XD_Conn=obj_Conn [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Property [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '============================================= [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] 'GetSQL 得到查询语句 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] ' [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '============================================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Public Property Let GetSQL(str_sql) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] XD_SQL=str_sql [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Property [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '=============================================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] 'PageSize 属性 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '设置每一页的分页大小 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '=============================================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Public Property Let PageSize(int_PageSize) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If IsNumeric(Int_Pagesize) Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] XD_PageSize=CLng(int_PageSize) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_error=str_error & "PageSize的参数不正确" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] ShowError() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Property [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Public Property Get PageSize [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If XD_PageSize="" or (not(IsNumeric(XD_PageSize))) Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] PageSize=10 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] PageSize=XD_PageSize [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Property [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img]

以上几个是在使用类的过程必需要指定的参数，曾经我在写属性的时候对每个传入的参数加上IsObject(obj_conn)等判断，为的是类的健壮，但是后来想来想去，这个对与ASP来说没有必要，不加还能加快点速度，至于为什么这样，我想各位在使用过程中也会发现，加还不如不加。这也是我经过了思想斗争以后才去掉了，只保留了一些必要的验证。一个参数就是当前页的获得，在程序中我用int_curpage来标识，这个的话放在类的创建过程中获得在好也没有了

[img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '======================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '设定一些参数的黙认值 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '======================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] XD_PageSize=10 '设定分页的默认值为10 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '======================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '获取当前面的值 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '======================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If request("page")="" Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_curpage=1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] ElseIf not(IsNumeric(request("page"))) Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_curpage=1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] ElseIf CInt(Trim(request("page")))<1 Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_curpage=1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Int_curpage=CInt(Trim(request("page"))) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Sub

到这里这个类分的功能基本已经实现了，只要在调用这个类的页面的URL后面加上page=n，它就会显示第n页的内容了，所以接下去要做的就是创建一个数据导航条了，我把它设计为类似以面的形式 9 3[1] [2] [3] [4] [5] [6] [7] [8] 4 :页次:1/8页共51条记录 7条/每页在页面里通过调用ShowPage()的方法显示出来，ShowPage可以在GetRS以后的任意位置调用，也可以调用多次

[img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Public Sub ShowPage() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Dim str_tmp [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_totalRecord=XD_RS.RecordCount [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If int_totalRecord<=0 Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_error=str_error & "总记录数为零，请输入数据" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Call ShowError() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If int_totalRecord="" Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_TotalPage=1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If int_totalRecord mod PageSize =0 Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_TotalPage = CLng(int_TotalRecord / XD_PageSize * -1)*-1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_TotalPage = CLng(int_TotalRecord / XD_PageSize * -1)*-1+1 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If Int_curpage>int_Totalpage Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] int_curpage=int_TotalPage [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '===================================================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '显示分页信息，各个模块根据自己要求更改显求位置 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '===================================================== [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write " [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_tmp=ShowFirstPrv '显示首页、前一页 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write str_tmp [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_tmp=showNumBtn '数字导航 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write str_tmp [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_tmp=ShowNextLast '下一页、末页 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write str_tmp [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_tmp=ShowPageInfo [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write str_tmp [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write "" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] end Sub [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img]

到这里类的功能才算完整（为了节省版面，我有些方法没有放上去，再下面附上全部完整代码）写一个简单页面测试一下

[img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] <% [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '把分页类包含进来 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] set conn = server.CreateObject("adodb.connection") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] conn.open "driver={microsoft access driver (*.mdb)};dbq=" & server.Mappath("pages.mdb") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '#############类调用样例################# [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '创建对象 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Set mypage=new xdownpage [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '得到数据库连接 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] mypage.getconn=conn [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] 'sql语句 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] mypage.getsql="select * from [test] order by id asc" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '设置每一页的记录条数据为5条 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] mypage.pagesize=5 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '返回Recordset [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] set rs=mypage.getrs() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '显示分页信息，这个方法可以，在set rs=mypage.getrs()以后,可在任意位置调用，可以调用多次 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] mypage.showpage() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '显示数据 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Response.Write(" ") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] for i=1 to mypage.pagesize [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] '这里就可以自定义显示方式了 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] if not rs.eof then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] response.write rs(0) & " " [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] rs.movenext [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] exit for [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] end if [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] next [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] %> [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img]

效果还不错,该有的全有了。分页过程中，还有一个比软麻烦的问题是，在带多个参数的URL中，如保证在页面转向的时候不掉失其它参数。我靠一个GetURL的过程来实现，并在生成导航时调用。

[img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Private Function GetURL() [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Dim strurl,str_url,i,j,search_str,result_url [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] search_str="page=" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] strurl=Request.ServerVariables("URL") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Strurl=split(strurl,"/") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] i=UBound(strurl,1) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_url=strurl(i)'得到当前页文件名 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_params=Request.ServerVariables("QUERY_STRING") [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If str_params="" Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] result_url=str_url & "?page=" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If InstrRev(str_params,search_str)=0 Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] result_url=str_url & "?" & str_params &"&page=" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] j=InstrRev(str_params,search_str)-2 [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] If j=-1 Then [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] result_url=str_url & "?page=" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] Else [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] str_params=Left(str_params,j) [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] result_url=str_url & "?" & str_params &"&page=" [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End If [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] GetURL=result_url [img]http://ftingchn.cnblogs.com/Images/OutliningIndicators/None.gif[/img] End Function

通过GetURL的处理，可以自动的获取当前面的文件名，和所有带的参数，实现了页面转换页不丢失参数。 [b]三、后记 [/b]通过这个分页类，解决了每次分页时需要重复写的分页部分代码，方便了编程，也使的提高了主要代码的可读性。也希望能给大家在编程过程中带来一点方便，由于本人水平有限,程序和文章中难免有错，还望大家批评指正。
