上一篇,下一篇过程代码-ASP教程,ASP应用

rem==上一篇==

rem================================================================

rem= 参数说明:

rem= pid当前id,prame:栏目前辍(如一般web_news表,字段时一般为wn_**,prame就代表wn)

rem= ptable(表前辍.如一般表名是:站点名_表名(shenzhe_news) ptable:就代表shenzhe)

rem= 说明:采用上面命名法,可使该过程达到通用

rem===============================================================

function getpre(pid,prame,ptable)

id = prame&"_id"

title = prame&"_title"

table = "city_"&ptable

url = "show_"&ptable

sql = "select top 1 "&id&","&title&" from "&table&" where "&id&"<"&pid&" order by "&id&" desc"

set rs = conn.execute(sql)

if rs.eof or rs.bof then

pre = "上一篇:没有新闻了"

else

pre = "<a href="&url&".asp?"&id&"="&rs(0)&">"&rs(1)&"</a>"

end if

getpre = pre

end function

rem = 下一篇

rem=============

rem= 参数函意和上过程一样

rem==========

function getnext(nid,nrame,ntable)

id = nrame&"_id"

title = nrame&"_title"

table = "city_"&ntable

url = "show_"&ntable

sql = "select top 1 "&id&","&title&" from "&table&" where "&id&">"&nid&" order by "&id&" "

set rs = conn.execute(sql)

if rs.eof or rs.bof then

nnext = "下一篇:没有新闻了"

else

nnext = "<a href="&url&".asp?"&id&"="&rs(0)&">下一篇:"&rs(1)&"</a>"

end if

getnext = nnext

end function

实现代码:

偶数据库里有表:

city_active city_date city_note

city_active主要字段有: ca_id,cd_title

city_date主要字段有: cd_id,cd_title

city_note主要字段有: cn_id, cn_title

这样引用就可:

在show_note.asp?cn_id=4里引用上一篇下一篇

<%=getpre(cn_id,"cn","note")%> 上一篇

<%=getnext(cn_id,"cn","note")%> 下一篇
