以下介紹用數據庫實現簡單計數器 '下面存為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) %> <% '更新每周每日數據 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%">今日訪問<%=rs("dayhit")%>次,本周訪問<%=rs("weekhit")%>次,總訪問<%=rs("hit")%>次</td></tr>'); <%rs.close set rs=nothing%>
