今天心情有点激动,想把"关于用DW+ASP实现分页技术的参考"分享给用DW+ASP做网页的朋友们.去掉只有"第一页,前一页,下一页,最后一页"的小痛苦 。
此效果最后的显示是:第N页[共*页] <<1 2 3 4 5 6 7 8 9 10 >>。
用DW+ASP做网页时,在绑定记录集后,代码页里马上出现以下代码：
<%
Dim Recordset1
Dim Recordset1_numRows
Set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = MM_数据库名_STRING
Recordset1.Source = "SELECT * FROM 表名"
Recordset1.CursorType = 0
Recordset1.CursorLocation = 2
Recordset1.LockType = 1
Recordset1.Open()
Recordset1_numRows = 0
%>
现在我们要来对代码做点修改，请在上面代码中修改为如下的代码：
<%
Dim I
Dim RPP
Dim PageNo
I=1
RPP=50
PageNo=CInt(Request("PageNo"))
’上面即是新插入的，
Dim Recordset1
Dim Recordset1_numRows
Set Recordset1 = Server.CreateObject("ADODB.Recordset")
Recordset1.ActiveConnection = MM_数据库名_STRING
Recordset1.Source = "SELECT * FROM 数据库名"
Recordset1.CursorType = 1 ’将上面代码的0改为1.
Recordset1.CursorLocation = 2
Recordset1.LockType = 1
Recordset1.Open()
Recordset1_numRows = 0 ’再在此行的下一行开始加入如下代码：
Recordset1.PageSize=RPP
If PageNo<=0 Then PageNo=1
If PageNo>Recordset1.PageCount Then PageNo=Recordset1.PageCount
Recordset1.AbsolutePage=PageNo
Sub ShowPageInfo(tPageCount,cPageNo)
Response.Write "第"&cPageNo&"页[共"&tPageCount&"页]"
End Sub
Sub ShowPageNavi(tPageCount,cPageNo)
If cPageNo<1 Then cPageNo=1
If tPageCount<1 Then tPageCount=1
If cPageNo>tPageCount Then cPageNo=tPageCount
Dim NaviLength
NaviLength=10 ’NaviLength：显示的数字链接个数
Dim I,StartPage,EndPage
StartPage=(cPageNo\NaviLength)*NaviLength+1
If (cPageNo Mod NaviLength)=0 Then StartPage=StartPage-NaviLength
EndPage=StartPage+NaviLength-1
If EndPage>tPageCount Then EndPage=tPageCount
If StartPage>1 Then
Response.Write "<a class=""pageNavi"" href=""?PageNo=" & (cPageNo-NaviLength) & """><<</a> "
Else
Response.Write "<font color=""#CCCCCC""><<</font> "
End If
For I=StartPage To EndPage
If I=cPageNo Then
Response.Write "<b>"&I&"</b>"
Else
Response.Write "<a class=""pageNavi"" href=""?PageNo=" & I & """>" & I & "</a>"
End If
If I<>tPageCount Then Response.Write " "
Next
If EndPage<tPageCount Then
Response.Write " <a class=""pageNavi"" href=""?PageNo=" & (cPageNo+NaviLength) & """>>></a>"
Else
Response.Write " <font color=""#CCCCCC"">>></font> "
End If
End Sub
%> 上面代码中：RPP：指定每页显示的记录条数。即每页显示几条数据。
[1] [2] [3] 下一页 |
