ASP分页的原理是什么？
写一个分页一定要用到下面这些属性吗
AbsolutePage ：当前记录在总页面中的页数编号
AbsolutePosition ： 绝对位置
PageCount ： 数据存在的页数
PageSize ：每页记录数
RecordCount ：统计记录集的记录总数
rs.recordcount : 返回记录总数
我看到有些分页不用这些属性也可以呢？
代码看不懂 ，想知道分页的思路和原理是什么？
如何做一个分页程序？
这在ASP中确实容易实现，但需要技巧，看看下面的分页代码和说明：
<anguage="vbscript"
dim conn
dim connstr
dim totalPut
dim CurrentPage
dim TotalPages
dim i,j
dim sql
dim rs
on error resume next
connstr="DBQ="+server.mappath("book.mdb")+";DefaultDir=;DRIVER={Microsoft Access Driver (*.mdb)};"
set conn=server.createobject("ADODB.CONNECTION")
conn.open connstr
set rs=server.createobject("adodb.recordset")
' 打开数据库
const MaxPerPage=18
' 定义每页文章显示数
if not isempty(request("page")) then
currentPage=cint(request("page"))
else
currentPage=1
end if
sql="select * from learning order by articleid desc"
Set rs= Server.CreateObject("ADODB.Recordset")
rs.open sql,conn,1,1
if rs.eof and rs.bof then
response.write "<p align='center'> 噢,还没有文章呢,正在添加中…</p>"
else
totalPut=rs.recordcount
' 数据库中文章数totalput
if currentpage<1 then
currentpage=1
end if
' 统计总页数currentpage
if (currentpage-1)*MaxPerPage>totalput then
if (totalPut mod MaxPerPage)=0 then
currentpage= totalPut \ MaxPerPage
else
currentpage= totalPut \ MaxPerPage + 1
end if
end if
if currentPage=1 then
showpage totalput,MaxPerPage,"index.asp"
showContent
showpage totalput,MaxPerPage,"index.asp"
else
if (currentPage-1)*MaxPerPage<totalPut then
rs.move (currentPage-1)*MaxPerPage
dim bookmark
bookmark=rs.bookmark
showpage totalput,MaxPerPage,"index.asp"
showContent
showpage totalput,MaxPerPage,"index.asp"
else
currentPage=1
showpage totalput,MaxPerPage,"index.asp"
showContent
showpage totalput,MaxPerPage,"index.asp"
end if
end if
rs.close
end if
set rs=nothing
conn.close
set conn=nothing
sub showContent
dim i
i=0
do while not rs.eof
>
<a href="openarticle.asp?id=<=rs("articleid")>"><=rs("title")></a>[点击:<=rs("hits")>]<br>
' 选择显示数据库内容
<
i=i+1
if i>=MaxPerPage then exit do
' 当显示记录大于maxperpage时结束这页
rs.movenext
loop
end sub
function showpage(totalnumber,maxperpage,filename)
' 求出当每页18篇文章时总共的页数
dim n
if totalnumber mod maxperpage=0 then
n= totalnumber \ maxperpage
else
n= totalnumber \ maxperpage+1
end if
response.write "<form method=Post action="&filename&">"
response.write "<p align='center'><font color='#000080'>>>分页</font> "
if CurrentPage<2 then
' 显示页数链接的条件
response.write "<font color='#000080'>首页 上一页</font> "
else
response.write "<a href="&filename&"?page=1&>首页</a> "
response.write "<a href="&filename&"?page="&CurrentPage-1&">上一页</a> "
end if
if n-currentpage<1 then
response.write "<font color='#000080'>下一页 尾页</font>"
else
response.write "<a href="&filename&"?page="&(CurrentPage+1)
response.write ">下一页</a> <a href="&filename&"?page="&n&">尾页</a>"
end ifc
response.write "<font color='#000080'>页次;</font><font color=red>"&CurrentPage&"</font><font color='#000080'>/"&n&"页</font>"
response.write "<font color='#000080'>共<b>"&totalnumber&"</b>篇文章 <b>"&maxperpage&"</b>篇文章/页
</font>"
response.write " <font color='#000080'>转到:</font><input type='text' name='page' size=4 maxlength=10
class=smallInput value="Currentpage&">"
response.write "<input class=buttonface type='submit' value='转到' name='cndok'></span></p></form>"
end function
