jsp中根据下拉列表的值显示不同的控件实例源码，jsp与html代码嵌套实例。以下就是相关的jsp实例源码：
<%@ page contentType=”text/html; charset=gb2312″ language=”java” import=”java.sql.*” errorPage=”" %>
<html>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=gb2312″>
<link href=”css/style.css” type=”text/css” rel=”stylesheet”>
<title>根据下拉列表的值显示不同的控件</title>
</head>
<script language=”javascript” type=”text/javascript”>
function ChangeItem(){
var name=form.name.value;
window.location.href=”index.jsp?name=”+name;
}
</script>
<%
String name=”";
if(request.getParameter(“name”)!=null){
name=request.getParameter(“name”);
}
%>
