DWR返回对象

package com.mol.info; package com.mol.info; public class User { public String name; public User(String name) { this.name = name; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

2、Java类代码:

package com.mol.info; public class UserDWR { public User say() { User user = new User("YangBang"); return user; } }

3、dwr.xml配置文件。如果DWR返回的的是对象，那个这个配置文件中，就要添加JavaBean对象的相关信息，至于web.xml中servlet的配置就不用讲了。

<?xml version="1.0" encoding="UTF-8"?> <dwr> <allow> <create creator="new" javascript="obj"> <param name="class" value="com.mol.info.UserDWR" /> </create> <!-- 配置的JavaBean对象 --> <convert converter="bean" match="com.mol.info.User"> </convert> </allow> </dwr>

4、JS接收DWR返回的代码:

<script type="text/javascript"> function test() { obj.say(cb); } function cb(data) { //在返回参数中，调用JavaBean的getName()方法，取得相应的值 document.getElementById("in").innerHTML = data.getName(); } </script>

1、Java代码:

public List<User> strList(){ User user = new User("YangBang"); User user1 = new User("WGR"); ArrayList<User> list = new ArrayList<User>(); list.add(user); list.add(user1); return list; }

2、dwr.xml配置文件代码:

<dwr> <allow> <create creator="new" javascript="list"> <param name="class" value="com.fs.listdwr.ListDwr" /> <include method="strList"/> </create> <convert converter="bean" match="com.fs.listdwr.User"> <param name="include" value="name" /> </convert> </allow> </dwr>

3、 JS接收DWR返回的代码:

function test() { list.strList(cb); } function cb(data) { for(var i=0;i<data.length;i++){ var value = data[i].name; var values = values + value; document.getElementById("in").innerHTML = values; } }

<script type="text/javascript"> function test() { map.myMapDwr(ab); } function ab(data) { var str = ""; for ( var key in data) { alert(key + "," + data[key]); var value = data[key]; str += value; } document.getElementById("in").innerHTML = str; } </script>
