| 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
