第一个jsp用到一个下拉框，里面innerHTML是第二个jsp<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%@page import="cc.model.Room"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>
<base href="<%=basePath%>"> <title>管理员登录</title> <script type="text/javascript">
function save() {
alert("I am an alert box!!")
} function loadXMLDoc(str) {
var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET", "admin/Admin!listRoom2?buildInfo=" + str, true);
xmlhttp.send();
}
</script> </head>
<%
List<String> buildList = (List<String>) session
.getAttribute("buildList");
List<Room> roomList = (List<Room>) session.getAttribute("roomList");

<body> draftAdd.jsp <select id="s1" onchange="loadXMLDoc(this.value)" style="font-family:Verdana, Arial, Helvetica, sans-serif;">

这是第二个jsp，里面有个action，我想点这个action之后页面不变
<%@ page language="java" import="java.util.*" pageEncoding="GB18030"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<%@page import="cc.model.Room"%>
<%@page import="cc.dto.DraftInfo"%>

String basePath = request.getScheme() + "://"
