用以下代码实现的三级联动下拉菜单[调用数据库数据]，没有显示菜单内容,帮我看看是哪里出问题了？谢谢！

Question

三个表：
P_BigClass(字段：BigClassID,BigClassName,descid),
P_SmallClass(字段：SmallClassID,BigClassName，SmallClassName,descid),
P_Sales(字段：SalesID,SmallClassName，SalesName,descid)

var arrSel=["BigClassName","SmallClassName","SalesName"];//arrSel定义了要修改的下拉框和xml数据的节点名称

<%
do while not rsP_BigClass.eof
%>
">
<%
set rsP_SmallClass=server.CreateObject("adodb.recordset")
rsP_SmallClass.open "Select * From P_SmallClass Where BigClassName='" & rsP_BigClass("BigClassName") & "' order by descid",conn,1,3
if not(rsP_SmallClass.bof and rsP_SmallClass.eof) then
do while not rsP_SmallClass.eof

Answer 1

asp么？代码问题很多，比如说sql查询，字符串没有带引号

也没有在下拉改变的时候调用onchange
