AjaxAnyWhere 实现页面局部刷新

2024-07-28 11:31:36   221人阅读

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"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
	<!-- Ajax配置开始,带编码转换(包括ajax提交的编码) --> 
    <filter>
        <filter-name>AjaxAnywhere</filter-name>
        <filter-class>org.ajaxanywhere.AAFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name><!-- 普通提交方式编码 -->
            <param-value>GB2312</param-value>
        </init-param>
        <init-param>
            <param-name>ajaxencoding</param-name><!-- AJAX提交方式编码 -->

        </init-param>
    </filter>
    
    <filter-mapping>
        <filter-name>AjaxAnywhere</filter-name>
        <url-pattern>*</url-pattern>
    </filter-mapping>
    
    
  <servlet>
    <servlet-name>AjaxAnyWhereTest</servlet-name>
    <servlet-class>org.ydd.test.AjaxAnyWhereTest</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>AjaxAnyWhereTest</servlet-name>
    <url-pattern>/AjaxAnyWhereTest</url-pattern>
  </servlet-mapping>

    <!-- Ajax配置结束 -->
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>
</span></strong>

4、index.jsp

<strong><span style="font-family:System;font-size:18px;"><%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>My JSP 'index.jsp' starting page</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
  </head>
  <body>
  	 <jsp:forward page="AjaxAnyWhereTest"/>
  </body>
</html>
</span></strong>


5、list.jsp


注：需要引入<script language="javascript" src=http://www.mamicode.com/"js/aa.js"></script>


<strong><span style="font-family:System;font-size:18px;"><%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="http://ajaxanywhere.sourceforge.net/" prefix="aa" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>ajaxAnywhere局部刷新</title>
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	
	<script language="javascript" src=http://www.mamicode.com/"js/aa.js"></script>	>
