急，在线！为什么会有这样的情况
楼主ireneki（阿雨）2003-08-05 22:48:00 在 Web 开发 / ASP 提问 我做的查询页面，结果显示页面我用了自动刷新：如下
<META HTTP-EQUIV="Refresh" Content="5">
问题出现了，自动刷新后，页面数据就都没了，这是怎么了。
而且分页功能也是一样，如果有的话，点击就什么都没了。这是怎么回事。请高手指点。立即结贴！ 问题点数：100、回复次数：10Top

<META HTTP-EQUIV=REFRESH CONTENT="1;URL=AddProduct.asp">
后面加上跳转的页面。。
看看行不行。Top

你的查询条件必须传递到下一个URL才行，比如你的查询是keyword=<%=reques("keyword")%>
那么你的应该包括aaa.asp?page=2&keyword=<%=reques("keyword")%>Top

把查询条件存在session里面，无论怎么刷新都没关系，不过这并不是一个好的办法Top

不行啊。怎么我用dw4自动生成的查询页面刷新没问题。自己手写代码就不行了呢。楼上的，怎么用session啊。我是菜鸟，帮帮忙。谢谢Top

可以试试手动刷新么。
<a href="javascript:location.reload();">刷新本页</a>
至于向下翻页的问题，一定是除了向下翻页的页码参数还有别的参数要传，
<a href="next.asp?Page=<%= Page+1%>&id=<%=request("id")%>"></a>Top

为什么是用自动刷新呢》
正如楼上所说
你查询的时候一定是带参数的。而你刷新的时候就没了参数！·（就是表单提交的时间在地址栏中所产生的如http://abc.com/search.asp?par=XXX par=XXX这一段就是表单提交时所产生的！）
你可以把表单的提交方式设为post,但同时是要把search.asp中接收数据的代码要改·
改成request("par")

查询参数要带着走.
<a href="next.asp?Page=<%= Page+1%>&canshu=<%=canshu%>></a>Top

Microsoft OLE DB Provider for ODBC Drivers 错误 "80040e07"
从字符串转换为 datetime 时发生语法错误。
/rz.asp，行16
这个错误怎么改啊。我不想把数据库字段改字符型。
<%
Dim temp,rd
temp = Request.form("mycity")
rd = Request.form("mytime")
%>
<%
set bz = Server.CreateObject("ADODB.Recordset")
bz.ActiveConnection = MM_bus_STRING
bz.Source = "SELECT * FROM dbo.SZ WHERE (DATEDIFF(day, RunDate, "&rd&") = 0) AND (MidStops=""&temp&"" OR Direction=""&temp&"")"
bz.CursorType = 0
bz.CursorLocation = 2
bz.LockType = 3
bz.Open()
bz_numRows = 0
%>
以上是我的部分代码。
那个RunDate出问题，到底怎么解决。Top
