在Struts框架里 ajax 异步处理返回的json中包含多种类型数据
我的前端JSP

<html>
  <head>

    <title><s:text name="login.title"/></title>
    <script type="text/javascript" src="${pageContext.request.contextPath }/js/jquery-1.7.2.js"></script>
<script type="text/javascript">

$(function(){
$("#username").blur(function(){
var username= $("#username").val();
var password= $("#password").val();
$.ajax({
url:"${pageContext.request.contextPath }/json/ajax",
type:"post",
dataType:"json",
timeout:1000,
data:{
"user.username":username,
"user.password":password
},
success:function(result){
var rs =eval(result);
$("#username").val(rs[0]);
},
error:function(){

}
});
});
});
</script>
  </head>

  <body>
   <div  style="margin: 10% auto ;background-color: aqua;width: 400;text-align:center;">
   <form action="${pageContext.request.contextPath }/user/login" method="post" >
   <table width="350" style="margin: 5% ;text-align:center;">
   <tr>
   <td width="50"><s:text name="user.username"/>:</td>
   <td width="200"><input type="text" name="user.username" id="username" /></td>
   <td width="50"><font id="pu" ></font></td>
   </tr>
   <tr>

   <s:text name="register"></s:text>
   </font>
   </td>
   </tr>
   </table>
   <s:fielderror ></s:fielderror>
   </form>
   </div>
  </body>
</html>

action

public class UserAction extends ActionSupport{
private User user;
private String result;

public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}

public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
public String initLogin(){
return SUCCESS;

}
public String validateLogin(){
if(user.getUsername()==null||"".equals(user.getUsername())){
addFieldError("user.username", "用户名不可以为空!");
}
if(user.getPassword()==null||"".equals(user.getPassword())){
addFieldError("user.password", "密码不可以为空!");
}
return SUCCESS;
}
public String login(){
return SUCCESS;

}
public String ajax(){
if(user.getUsername().length()>6){
result ="用户名符合规范!";

}else{
result ="用户名不符合规范!";
}
return SUCCESS;
}

}

Struts.xml

<package name="json" namespace="/json" extends="json-default">
     
     <interceptors>
     
     <interceptor name="login" class="com.hello.interceptor.CheckInterceptor"></interceptor>
     
     <interceptor-stack name="myStack">
     <interceptor-ref name="login">
     <param name="excludeMethods">initLogin</param>
     </interceptor-ref>
     <interceptor-ref name="defaultStack"></interceptor-ref>
     </interceptor-stack>

     </interceptors>
     <default-interceptor-ref name="myStack"/>

     <action name="ajax" class="com.hello.action.UserAction" method="ajax">
     <result type="json"></result>
     <param name="includeProperties">String</param>
</action>
    </package>

现象:前台接受到的json中包含了result 还有user 对象请问下应该怎么取出来
------解决思路----------------------



//前台接受的是后台返回的JSON数据，只要通过succes回调函数的result点属性就行了！

//JOSN可以类似对象那样点出来。。。
