我想实现一个功能，当点击查询按钮时，根据不同的下拉列表，显示不同的网页，该怎么实现例如当下拉列表显示“按指导老师查询”时，链接到以下页面
<%@ page language="java" import="java.util.*" pageEncoding="GB2312"%>
<%@ page import="java.sql.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<%!String trans(String t)
{
String result=null;
byte temp[];
try
{
temp=t.getBytes("iso-8859-1");
result=new String(temp);
}
catch(Exception e)
{
}
return result;
} %>
<body>
<%
Connection con;
Statement sql;
ResultSet rs;
String t=request.getParameter("ti");
try
{
Class.forName("com.mysql.jdbc.Driver");
}
catch (Exception e)
{
out.print(e);
}
try
{
String uri="jdbc:mysql://localhost/lunwen";
con=DriverManager.getConnection(uri,"root","789456");
sql=con.createStatement();
rs=sql.executeQuery("SELECT * FROM lunwentopic WHERE lunwentimu LIKE '%"+trans(t)+"%'");

out.print("<tr>");
out.print("<th width=160>"+"论文题目"+"</td>");
