这个比较jquery、单纯ajax异步简单多了，不多说了直接上代码。
需要引入：ajaxanywhere-1.2.1.jar （最新）和 /ajaxAnyWhereDemo/WebRoot/js/aa.js ，免费下载地址http://download.csdn.net/detail/xuke6677/8064977
目录结构如下：
1、ListBean.java 实体类
<strong><span style="font-family:System;font-size:18px;">package org.ydd.test;
public class ListBean {
private String id;
private String name;
private String sex;
private String work;
private String address;
//get(),set()…… 省略
}</span></strong>
2、 AjaxAnyWhereTest.java 后台servlet
<strong><span style="font-family:System;font-size:18px;">package org.ydd.test;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class AjaxAnyWhereTest extends HttpServlet {
private static final long serialVersionUID = -5750167075517567170L;
List<ListBean> rs = new ArrayList<ListBean>();
@Override
public void init() throws ServletException {
ListBean userBean = new ListBean();
userBean.setId("1");
userBean.setName("张三");
userBean.setSex("123");
userBean.setWork("prom");
userBean.setAddress("fdsfsd");
rs.add(userBean);
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
ListBean userBean = new ListBean();
String id= request.getParameter("id");
if(!"".equals(id) && id!=null){
userBean.setId(id);
userBean.setName(request.getParameter("name"));
userBean.setAddress(request.getParameter("address"));
userBean.setSex(request.getParameter("sex"));
userBean.setWork(request.getParameter("work"));
rs.add(userBean);
}
if(rs.size()>0){
request.setAttribute("queryList", rs);
}
request.getRequestDispatcher("list.jsp").forward(request, response);
}
}
</span></strong>
3、web.xml
<strong><span style="font-family:System;font-size:18px;"><?xml version="1.0" encoding="UTF-8"?>
