js如何接收处理后台传来的list

list<String>从后台传来，如何在js里接收并处理为数组，页面只能用el表达式接收数据

List数据，从java后台传至js中接收的方法：

新建bean类

public class Test {

private int Id;

public int getId() {

return Id;

}

public void setId(int id) {

Id = id;

}

}

2.再建返回List<Bean类>的java方法

public List<Test> list(){

Test t=new Test();

t.setId(1);

List<Test> list = new ArrayList<Test>();

list.add(t);     

return list;

}

3.配置web.xml——补加导入dwr配置的代码

<servlet> 

<servlet-name>dwr-invoker</servlet-name>  <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>

<init-param>

<param-name>debug</param-name>

<param-value>true</param-value>

</init-param>

</servlet> 

<servlet-mapping>    

<servlet-name>dwr-invoker</servlet-name>

<url-pattern>/dwr/*</url-pattern>

</servlet-mapping>

4.配置dwr.xml——creator+concert

<allow>

<create creator="new" javascript="service">

<param name="class" value="com.telek.dwr.Service" />

</create>

<convert converter="bean" match="com.telek.dwr.Test">

<param name="include" value="id"/>

</convert>

</allow>

5.js文件中正确接收

function callBackHello(data){

alert(data[0].id);

}

function testList(){

service.list(callBackHello);

}
