DWR返回对象

标签：javascript   servlet   jsp   dwr   

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>
