程序原理:先显示顶踩的样子,通过点击顶或踩触发postDigg(ftype,aid)函数,这里通过ajax发送到php页面处理,该页面处理好数据后返回
间的所有html代码,这时可能再执行一次getDigg(aid)来把内容显示到原来位置。JS通过检测cookie("diggid")的值与当前信息的id有否重复,有则判断为已经顶过。
下面是ASP的digg_ajax.asp代码,大家作些各自的修改就可以用:

<%@ CODEPAGE=936 %>
<%
Response.CodePage=936
Response.Charset="gb2312"
Response.AddHeader "Pragma", "no-cache"
Response.AddHeader "cache-ctrol", "no-cache"
Response.CacheControl = "no-cache"
Response.Flush
%>


<%
id = request.QueryString("id")    '进行数值处理
action = request.QueryString("action")
saveid = request.Cookies("diggid")
if instr(","&saveid&",", ","&id&",") > 0 then response.end

set rs=server.createobject("adodb.recordset")
rs.open "select top 1 * from info where is_pass=1 and id=" & id,conn,1,3
if rs.eof then
' msgAlert "要查看的信息不存在或未审核。"
 response.End()
else
 if action = "good" then rs("act_good") = rs("act_good") + 1
 if action = "bad" then rs("act_bad") = rs("act_bad") + 1
 rs.update
 act_good = rs("act_good")
 act_bad = rs("act_bad")
end if
rs.close

if act_good+act_bad=0 then
 act_good_per = 0
 act_bad_per = 0
else
 act_good_per=cint(act_good/(act_good+act_bad)*100)
 act_bad_per=100-act_good_per
end if

set rs=nothing
