昨天刚用prototype做了个AJAX的例子,今天用了下DWR
才发现AJAX竟然也可以如此傻瓜式的实现,安装和xml的配置很多地方都有，我也不写了。：

dwr.xml如下:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE dwr PUBLIC

"-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"

"http://www.getahead.ltd.uk/dwr/dwr10.dtd">

<dwr>

<allow>

</create>

</create>

</convert>

</allow>

</dwr>

jsp页面如下:

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>

<jsp:directive.page import="com.lan.Demo"/>

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>My JSP 'dwr.jsp' starting page</title>

<!--

-->

function test(){

Demo.hello("lanzhengwu",callhello);

}

function callhello(msg){

alert(msg);

}

function callback(msg) {

document.getElementById("linkid").innerHTML=msg;

}

var sign=false;

function show(uid){

if(sign==false){

Demo.getaccount(uid,callback);

sign=true;

}else if(sign==true){

document.getElementById("linkid").innerHTML="######";

sign=false;

}

function display(){

Demo.setinfo(backinfo);

}

function backinfo(msg) {

var s="";

s+=msg[1]+" ";

s+="姓名:"+msg[0].name+" ";

s+="性别:"+msg[0].sex+" ";

s+="年龄:"+msg[0].age+" ";

s+="工作于:"+msg[0].work+" ";

s+="职位:"+msg[0].job+" ";

document.getElementById("rep").innerHTML=s;

}

</script>

</head>

<body>

This is my JSP page. <br>

<a href="#" onmouseover="display()" >放上来显示信息</a>

<table>

</table>

</body>

</html>

Bean 代码如下:

package com.lan;

import java.util.ArrayList;

public class Demo {

String name="";

String sex="";

int age=0;

String job="";

String work="";

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getJob() {

return job;

}

public void setJob(String job) {

this.job = job;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

public String getWork() {

return work;

}

public void setWork(String work) {

this.work = work;

}

public String hello(String name){

return "您好!"+name+",开始你的DWR学习啦!";

}

public double getaccount(int id){

double money=0.0;

if(id==1){

money=1234.00;

}else{

money=8765.00;

}

return money;

}

public ArrayList<Object> setinfo(){

ArrayList<Object> array=new ArrayList<Object>();

Demo demo=new Demo();

demo.setName("lanzhengwu");

demo.setAge(19);

demo.setSex("男");

demo.setJob("Java程序员");

demo.setWork("001f");

array.add(demo);

array.add("hello");

return array;

}
