求助一个投票过程的日志记录顺序如何修改？
判断投票时有的项目的选项没有选择就跳回投票页面，但是刚投的空票却将投票的iP和时间记录到数据库里面了。要如何才能先判断再记录呢？
代码如下：
<%option explicit%>
<%response.expires = 0%>
<!--#include file= "common/conn.asp "-->
<%
'验证投票日期是否有效
'startTime 所指那天为投票开始的第一天
'endTime 所指那天为投票结束的第一天
'endTimeValid 结束时间是否有效
'投票还没开始返回 1
'投票已经结束返回 -1
'投票时间有效返回 0
function ValidVoteDate(startTime, endTime, endTimeValid)
if DateDiff( "d ", startTime, Date()) < 0 then
ValidVoteDate = 1
elseif endTimeValid and DateDiff( "d ", Date(), endTime) <= 0 then
ValidVoteDate = -1
else
ValidVoteDate = 0
end if
end function
'验证投票间隔是否有效
function ValidVoteInterval(conn, rs, subjectID, clientIP, intervalValue, intervalUnit)
dim sql
sql = "select top 1 logTime from voteLogs where subjectID= " & CLng(subjectID) & " and clientIP= ' " & Replace(clientIP, " ' ", " ' ' ") & " ' order by logID desc "
rs.Open sql, conn, 1, 1
if not rs.eof then
if DateDiff(intervalUnit, rs( "logTime "), Now()) > intervalValue then
ValidVoteInterval = true
else
ValidVoteInterval = false
end if
else
'记录不存在，些 IP 还没有针对本主题进行过投票
ValidVoteInterval = true
end if
rs.Close
end function
'为一项投票
'仅被 UpdateOptions 调用
function UpdateOption(conn, itemID, validOptionsCnt)
dim votedOptionsCnt
votedOptionsCnt = request.Form( "option_ "&itemID).count
if validOptionsCnt> 0 and votedOptionsCnt> validOptionsCnt then
'validOptionsCnt <=0 表示不限制选项数
exit function
elseif votedOptionsCnt=0 then
response.Write( "未完成项目选项选择！请重新选择！ ")
response.Write( " <a href= " "# " " onclick= " "javascript:window.close();return false " "> 关闭窗口 </a> ")

[解决办法]
function UpdateOption(conn, itemID, validOptionsCnt)
dim votedOptionsCnt
votedOptionsCnt = request.Form( "option_ "&itemID).count
if validOptionsCnt> 0 and votedOptionsCnt> validOptionsCnt then
'validOptionsCnt <=0 表示不限制选项数
exit function

response.Write( "未完成项目选项选择！请重新选择！ ")

exit function
response.end
end if
dim i, optionIDStr
for i=1 to votedOptionsCnt
optionIDStr = optionIDStr & ", " & CLng(request.Form( "option_ "&itemID)(i))
next
dim sql, answer
if Len(optionIDStr) > 1 then
sql = "update options set optionValue=optionValue+1 where itemID= " & CLng(itemID) & " and optionID in ( " & Mid(optionIDStr, 2) & ") "
conn.Execute sql
end if
end function
----------------------------
if validOptionsCnt> 0 and votedOptionsCnt> validOptionsCnt then
这句是验证吗？
---------------------------
太长了 再添加到数据库前验证一下就好了？
不符合就返回，用javascript返回上一页
是这个问题吗？
