联动已经解决 但是写入不了数据库 提交后数据库会自动增加一列 但是是空的

<!--#include file="heck.asp"-->
<script language="JavaScript">
sall=new Array();
<%
dim i
i=0
set rs=server.CreateObject("adodb.recordset")
    sql="select * from khlist order by id asc"
    rs.open sql,conn,1,1
 if not rs.eof then
 do until rs.eof
%>
sall[<%=i%>]=new Array("<%=rs("khbm")%>","<%=rs("id")%>","<%=rs("khname")%>");

<%
i=i+1
rs.movenext
loop
end if
rs.close
set rs=nothing
%>

function changeselect(selvalue) 
   {   
      document.all.xl.length=0; 
      var selvalue=selvalue;
      var i;

[解决办法]
rs("x1") = Request.Form("x1")
rs("d1") = Request.Form("d1")

您定义的变量“<select name="dl" ID="dl"”是字母"L" ，获取的是d1数字“1”
