ASP如何实现P数字分页效果
最近网站改版正好发现原来的分页不带数字的,只有首页 上页 下页 末页 然后是select的跳转,都是以前比较流行的,而现在比较流行的是数字分页在中间,正好研究并分享下,需要的朋友可以参考下
国外的核心代码:
代码如下:

'digg style pagination script in asp.. written by Moazam...
function getPaginationString(page, totalitems, limit, adjacents, targetpage)
'defaults
if not isnumeric(adjacents) then adjacents = 1 end if
if not isnumeric(limit) then limit = 15 end if
if not isnumeric(page) then page = 1 end if
if targetpage = "" then targetpage = "http://www.xue163.com/" end if
margin = ""
padding=""
'other vars
prev = page - 1 'previous page is page - 1
nextPage = page + 1 'nextPage page is page + 1
lastpage = Ceil(totalitems , limit) 'lastpage is = total items / items per page, rounded up.
lpm1 = lastpage - 1 'last page minus 1
' Now we apply our rules and draw the pagination object.
' We're actually saving the code to a variable in case we want to draw it more than once.
pagination = ""
if lastpage > 1 then
pagination = pagination & "<divpagination"""
if margin <> "" OR padding <> "" then
pagination = pagination & ""
if margin <> "" then
pagination = pagination & "margin: margin"

pagination = pagination & "padding: padding"

pagination = pagination & """"

看了有些头晕,还是看点简单的吧,asp与php思想差不多啊,参考了dedecms的修改方法
效果图:
核心代码:
代码如下:
ps=cint(pageno)-2
if ps<1 then
ps=1
end if
pe=clng(pageno)+5
if pe>mpage then pe=mpage
for i=ps to pe
if i=pageno then
lb=lb&"<strong>"&i&"</strong>"
else
lb=lb&"<a href=""/list/list_"&theid&"_"&i&".htm"">"&i&"</a>"
end if
next

代码如下:
