這是我依造前面的高手做的程式
但是第一個下拉是選到什麼,第二個都是出現一樣
請問各位高手要怎麼修該??
如果可以的話可以講一下資料那邊要怎麼設

<%@ page import="java.sql.*" %>
<%@page import="java.io.* "%>
<%@ page contentType="text/html;charset=Big5" %>
<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=big5">
<title>Test</title>
</head>

<body>
<%
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection Conn = DriverManager.getConnection("jdbc:sqlserver://192.168.31.51:1433;databaseName=bpp","sa","12345");

int i=0;
Statement stmt=Conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
Statement stmt2=Conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String SQL = "Select id From a";
ResultSet rs = stmt.executeQuery(SQL);
%>

<SCRIPT LANGUAGE="javascript">
<!--
function ChangeSelect(city, region)
{
val = city.options[city.options.selectedIndex].value;

<%while(rs.next()){

String SQL2 = " select * from city " + rs.getString("id") ;
ResultSet rs2 = stmt2.executeQuery(SQL2);

%>
if (val == '<%=rs.getString("id")%>')
{

<%while(rs2.next()){
i++;
}%>
region.length = <%=i%>;
<%
i=0;
rs2.first();
do{%>
region.options[<%=i%>].value = '<%=rs2.getString("aa")%>';
region.options[<%=i%>].text = '<%=rs2.getString("aa")%>';
<%
i++;
}while(rs2.next());
i=0;%>

}
<%}
rs.first();%>
}
-->
</script>

<form name="selection">
<select name=city onChange="ChangeSelect(document.selection.city,document.selection.region)" size="1">
<option>==請選擇城市==</option>
<%do{%>
<option value="<%=rs.getString("id")%>"><%=rs.getString("id")%></option>
<%}while(rs.next());%>
</select><BR>
