JQuery AJAX调用 - 如何捕获响应JSON？

jQuery:

$(document).ready(function(){
 $('#QuoteSearch').submit(function(){
  alert("in jquery");
  $.ajax({
      url: "ajaxJQuery",
      type: "POST",
      data: {username: $("#username").val(), password: $("#password").val()},
      dataType: "json",  
      error: function(){  
          alert('Error');
      },
      success: function(data){   
       alert('SUCCESS');
       alert(data);
      }
  });
  return false;
 });
});

<form> code:

<form id="Quote Search">   
  <textfield name="username" id="username" label="User Name" />  
  <textfield name="password" id="password" label="Password" />  
  <submit/>  
</form>  
<div id="coupon">  
  Name = <property value="name" /> and Code = <property value="code" />  
</div> 

Action class:

private String username;
private String password;
private String name = "Sheela";
private String code = "qwert";

public String execute() throws Exception {  
  System.out.println("inside execute");  
  name = username;  
  code = password;  
  return SUCCESS;  
 }  

Question: How do I access the JSON returned by the Action class? I am using struts2-json-plugin, which automatically converts the Action class to JSON. I want to be able to update the div tag based on the JSON response.

问题:如何访问Action类返回的JSON?我正在使用struts2-json-plugin,它自动将Action类转换为JSON。我希望能够根据JSON响应更新div标签。

This is what I see in the console:

这是我在控制台中看到的:

DEBUG (org.apache.struts2.json.JSONUtil) [JSON]
{"code":"HELLO","name":"ABCD","password":"HELLO","username":"ABCD"}

But I am not sure how to capture this in the JSP. Please help. gh

但我不确定如何在JSP中捕获它。请帮忙。 GH

The JSON response from the server should be in the data parameter in your success handler. Have you looked at what that contains?

来自服务器的JSON响应应该在成功处理程序的data参数中。你看过那里包含的东西了吗?
