关于Ajax的问题，急急急！！！
会议名称 ，今天开会个数，本周开会个数，本月开会个数
要分开显示，会议名称 ，今天开会个数，
会议名称，本周开会个数
会议名称。本月开会个数
我用了一个Ajax.js,2个jsp页面
个数显示不出来，是不是我的方法有问题，
请各位大侠们帮看看，不想看的也可以用你的方法写一下，但最要不要用到底层的代码，就是页面的代码！
谢谢！！！非常感谢！！！
第一个页面：
--------------------------------------------------------
<%@ page language="java" contentType="text/html; charset=UTF-8"%>
<%@ taglib uri="webwork" prefix="ww"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
<head>
<script type="text/javascript">
var dep=null;
function getMembers(sunn){
if(sunn!="null"){
hideMenu();
dep = sunn;
var url="select.jsp";
var params = 'sunn=' + sunn;
sendRequest(url,params,'GET',showMembers);
}
}
function showMembers(){
if (httpRequest.readyState == 4) {
if (httpRequest.status == 200) {
var membersData = httpRequest.responseXML.getElementsByTagName("member");
var mdisplay = '';
for(var i=0;i<membersData.length;i++){
mdisplay += ' ';
mdisplay += membersData[i].childNodes[1].firstChild.nodeValue;
mdisplay += '<br>';
}
document.getElementById(dep).parentNode.style.display='block';
document.getElementById(dep).innerHTML=mdisplay;
} else { //页面不正常
alert("您请求的页面有异常");
}
}
}
function hideMenu(){
if(!dep) return ;
if(document.getElementById(dep).parentNode.style.display=='none'){
document.getElementById(dep).parentNode.style.display='block';
} else if(document.getElementById(dep).parentNode.style.display='block'){
document.getElementById(dep).parentNode.style.display='none';
document.getElementById(dep).innerHTML=' ';
return ;
}
}
</script>
</head>

第2个页面：

String path = request.getContextPath();

%>
<%
Map map = new HashMap();
String d1 = "<members><a href="+"findVtrials.action"+"><ww:property value="+"currentdaycount"+"/></a></member>";
String d2 = "<members><a href="+"findVtrials.action"+"><ww:property value="+"currentweekcount"+"/></a></member>";

map.put("d1",d1);
map.put("d2",d2);
map.put("d3",d3);
map.put("d4",d4);
String sunn= request.getParameter("depart");
if(sunn==null) sunn = "d1";
StringBuffer sb = new StringBuffer();
sb.append("<members>");
sb.append(map.get(sunn).toString());
sb.append("</members>");
out.write("<?xml version='1.0' encoding='gb2312' ?>");
out.write(sb.toString());
%>
[解决办法]
httpRequest 这个对象怎么出来的 没看到你定义啊？ httpRequest = new ActiveXObject("Microsoft.XMLHTTP")
[解决办法]
var dep=null;
function getMembers(sunn){
if(sunn!="null"){
hideMenu();
dep = sunn;
var url="select.jsp";
var params = 'sunn=' + sunn;
sendRequest(url,params,'GET',showMembers);
}
}
[解决办法]
给你一个httpRequest函数：
function GetXMLBlock(url){ var req=null; try { req = new XMLHttpRequest(); } catch (e) { alert("GetXMLBlock 1"); req = null; } if (!req && typeof(ActiveXObject) != "undefined"){ req = new ActiveXObject("Microsoft.XMLHTTP"); } try { var a = req.open('GET', url, false); //req.setRequestHeader("If-Modified-Since","0"); req.setRequestHeader("Content-Type","utf-8"); req.send(null); if (req.readyState == 4) { if (req.status == 200) { return req.responseXML; } alert("GetXMLBlock 2:"+req.status); return null; } } catch (ex) { alert("GetXMLBlock 3 :"+ex); return null; } alert("GetXMLBlock 4"); return null;}
