下拉菜单的连动问题

我的第二个下拉菜单中的内容想根据第一个下拉菜单的选项的不同，从数据库中提取不同的数据，我该怎么作，我已经用呢很多的办法，都不能实现，望解答！！！！！！，我现在的最大问题是我从”数据库“中提出的rs，怎么加入到<script language="JavaScript">中的函数onchange（）中去，下面是我的代码
<html>
<head>
<form name="denyu" METHOD=POST action="denyu1.jsp">
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>灯语</title>
</head>
<body>
<%@page contentType="text/html; charset=gb2312"%>
<%String aaaa="dwqdeer";%>
<%@page language="java" import="java.sql.*"%>
<%!
Connection conn1=null;
ResultSet rs=null;
Statement stmt1;%>
<%
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn1=DriverManager.getConnection("jdbc:odbc:dddd","","");
stmt1=conn1.createStatement();
%>
<script Language="JavaScript" import="java.sql.*">
Connection conn2=null;
ResultSet rs2=null;
Statement stmt2;
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn2=DriverManager.getConnection("jdbc:odbc:dddd","","");
stmt2=conn2.createStatement();
rs2=stmt2.executeQuery("select * from table1");
var my;

while(rs2.next()){
my="String(rs2.getString(1))";
}
///我就是没法的到"my"."my"本来应该是数组的，我为呢查错写成现在这样

function change(char)
{var i;

var ss=char.value;

for (i=0;i<9; i++)
{
if (ss ==my) ///我就是没法的到"my"
{
document.denyu.village.options[0]=new Option("fda","");

}

}
}
</script>
