如何轻松打造ASP计数器

  【IT168 服务器学院】以下介绍用数据库实现简单计数器
  ''下面存为count.html
  <%
  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.html"></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
