JSON結果得到控制器的JSON值

Question

返回和功能，我得到它包含

{ 
    "readyState":4, 
    "responseText":"{\"Success\":0,\"Failed\":0}", 
    "responseJSON":{ 
     "Success":0, 
     "Failed":0 
    }, 
    "status":200, 
    "statusText":"OK" 
} 

我怎樣才能把成功和失敗值的對象？

data.Successand JSON.parse（數據）不工作

Answer 1

你不需要解析因爲IS已經是一個對象：

var obj = {"readyState":4,"responseText":"{\"Success\":0,\"Failed\":0}","responseJSON":{"Success":0,"Failed":0},"status":200,"statusText":"OK"}; 
var failed = obj.responseJSON.Failed; 
var success = obj.responseJSON.Success; 

Answer 2

var json_data = '{"readyState":4,"responseText":"{\"Success\":0,\"Failed\":0}", 
"responseJSON":{"Success":0,"Failed":0},"status":200,"statusText":"OK"}'; 

var obj = JSON.parse(json_data); 


alert(obj.responseJSON.Success); // for success that in responseJSON 
alert(obj.responseJSON.Failed); 

謝謝:)
