asp伪继承初探_实例代码-ASP编程

其中使用到一个分页类CPaging

代码如下:

Class CPaging 
Public RS ' RecordSet对象 
Public Mark ' 指针标签 
Private sSize ' 每页显示数 
Private sTotal ' 总记录数 
Private sPage ' 当前页码 
Private sCount ' 总页码 
Private Sub Class_Initialize 
sSize = 20 
sPage = 1 
sCount = 1 
End Sub 
Private Sub Class_Terminate 
Closeobj RS 
End Sub 
'每页显示数 
Property Let Size(Value) 
sSize = Value 
End Property 
Property Get Size 
Size = sSize 
End Property 
'当前页码 
Property Let Page(Value) 
If Not IsNumeric(Value) Then 
sPage = 1 
Else 
sPage = Value 
End If 
End Property 
Property Get Page 
If (sPage - 1) * sSize > sTotal Then 
If sTotal Mod sSize = 0 Then 
Page = Total \ sSize 
Else 
Page = Total \ sSize +1 
End If 
ElseIf sPage < 1 Then 
Page = 1 
Else 
Page = sPage 
End If 
End Property 
'总页码 
Property Get Count 
If sTotal Mod sSize = 0 Then 
Count = sTotal \ sSize 
Else 
Count = sTotal \ sSize + 1 
End If 
End Property 
'总记录数 
Property Get Total() 
Total = sTotal 
End Property 
Public Function Open(Byval SQLString) 
Try DB.Openquery(RS,SQLString) 
sTotal = RS.RecordCount 
End Function 
End Class

以下是调用页
代码如下:

Dim Products 
Set Products = New CPaging 
With Products 
.Size = 15 '每页显示数 
.Page = PageNum '当前页 
End With 
Try Products.Open(ListSQL) 
If Products.RS.Bof and Products.RS.Eof then 
Response.Write("<TR><TD colspan=8>查找无记录</TD></TR>") 
Else 
Dim i 
i = 0 
Products.RS.Move (Products.Page - 1) * Products.Size 
Do While Not Products.RS.Eof 
Response.Write("<TR onmouseup=MouseUp(this); onmousedown=MouseDown(this); onmouseover=MouseOver(this); onclick=Click(this); onmouseout=MouseOut(this);>"&vbCrLf) 
Response.Write("<TD align=middle nowrap>" & Products.RS("ProductsClassName") & "</TD>"&vbCrLf) 
Response.Write("<TD align=left nowrap>" & Products.RS("ProductsName") & " </TD>"&vbCrLf) 
Response.Write("</TR>"&vbCrLf) 
i=i+1 
If i >= Products.Size Then Exit Do 
Products.RS.MoveNext 
Loop 
End If
