选择下拉框内项目时页面刷新，但是依旧显示所有内容，没有刷出分类效果。高手看一下哪里没改好。

程序代码：
    if nowxiaoqu="" then
    sql="select * from yezhu order by xiaoqu,id"
    else
    sql="select * from yezhu where xiaoqu="&nowxiaoqu&" order by id"
    end if

sql="select * from yezhu where ((month(shui)>="&month(date())&" and month(shui)<="&month(date()+5)&" and (shui)>="&day(date())&" and day(shui)<="&day(date()+5)&") and year(wenhou)<>"&year(date())&")"
在if语句后，sql语句又重写了

以下是引用dzt0001在2010-11-20 13:26:58的发言：

    sql="select * from yezhu order by xiaoqu,id"
    else
sql="select * from yezhu where ((month(shui)>="&month(date())&" and month(shui)<="&month(date()+5)&" and (shui)>="&day(date())&" and day(shui)<="&day(date()+5)&") and year(wenhou)<>"&year(date())&")"
在if语句后，sql语句又重写了
  已经去掉了这句  sql="select * from yezhu where xiaoqu="&nowxiaoqu&" order by id"
    end if
但是还是不能按小区显示啊，依然显示所有小区。

核心在这句上：  <select name="xiaoqu" onChange="form2.submit()">也就是说当对select操作后，会执行form2的提交，并刷新整个页面，也就是重新执行一次上面的ASP页面！
那么显示的就是最后一次SQL查询到的数据，最后一次是什么SQL呢？你自己看看吧！

gupiao1752010-11-20 16:48
最后一个执行的sql="select * from yezhu where ((month(shui)>="&month(date())&" and month(shui)<="&month(date()+5)&" and (shui)>="&day(date())&" and day(shui)<="&day(date()+5)&") and year(wenhou)<>"&year(date())&")"  将是你刷新后内容显示的结果！这句能分类吗？请参考数据库结构表看看！
如果希望分类，你需要改动的地方还是满多的。
1。表单更改：<form name="form2" action="?act=fenlei">多加了一个判断。
2。在ASP页面里加判断：建议加到<form name="form1" >下面去，具体看效果而定！
   if request("act")='fenlei' then
     ...这里加分类的SQL语句，然后将分类查到的数据再一次显示到表格里去，代码比较多！
     response.end '结束语句执行，不然后面就会显示第二个全部小区数据的了。
    end if

<%
    if nowxiaoqu="" then
    sql="select * from yezhu order by xiaoqu,id"
    else
    sql="select * from yezhu where xiaoqu="&nowxiaoqu&" order by id"
    end if

sql="select * from yezhu where ((month(shui)>="&month(date())&" and month(shui)<="&month(date()+5)&" and (shui)>="&day(date())&" and day(shui)<="&day(date()+5)&") and year(wenhou)<>"&year(date())&")"
最后那个sql不要。：sql="select * from yezhu where ((month(shui)>="&month(date())&" and month(shui)<="&month(date()+5)&" and (shui)>="&day(date())&" and day(shui)<="&day(date()+5)&") and year(wenhou)<>"&year(date())&")"

最后那句不要的话，列表会显示所有业主，当然也可以选择下拉框小区，但是我想的是只显示即将或已经到期缴费的业主。
