以下介绍用数据库实现简单计数器

'下面存为count.ASP

＜%

Set conn=Server.CreateObject("ADODB.Connection")

conn.Open "driver={Microsoft Access Driver (*.mdb)};dbq="& Server.MapPath("count.mdb")

%＞

＜%on error resume next%＞

＜%sql="update count set hit=hit+1%＞＜%conn.Execute(sql)%＞

＜%sql = "select * from count

set rs=conn.execute(sql)

%＞

＜%

'更新每周每日数据

lasthit=rs("lasthit")

tdate=year(Now()) & "-" & month(Now()) & "-" & day(Now())

if trim(lasthit)=trim(tdate) then

sql="update site set dayhit=dayhit+1 where id="&request("id")

conn.Execute(sql)

' response.write "success"

else

sql="update site set dayhit=1 where id="&request("id")

conn.Execute(sql)

' response.write "error"

end if

sql="update site set lasthit='"&tdate&"' where ID="&request("id")

conn.Execute(sql)

p_year=CInt(year(Now()))-CInt(year(lasthit))

p_month=CInt(month(Now()))-CInt(month(lasthit))

p_day=CInt(day(Now()))-CInt(day(lasthit))

period_time=((p_year*12+p_month)*30+p_day)

if cint(period_time)=＜cint(7) then

sql="update site set weekhit=weekhit+1 where id="&request("id")

conn.Execute(sql)

else

sql="update site set weekhit=1 where id="&request("id")

conn.Execute(sql)

end if

%＞

document.write('＜tr＞＜td width="100%"＞今日访问＜%=rs("dayhit")%＞次,本周访问＜%=rs("weekhit")%＞次,总访问＜%=rs("hit")%＞次＜/td＞＜/tr＞');

＜%rs.close

set rs=nothing%＞

'用＜script language="javascript1.1" src="count.ASP"＞＜/script＞在要统计的页面调用即可.

建立数据库:建一个count的MDB库,再建一个表count,表中字段为

hit 数字型

dayhit 数字型

weekhit 数字型

lasthit 日期型
