jQuery的嵌套響應陣列發行

Question

我有一個驗證用戶名/密碼功能：

這裏是JSON響應：

{"data":{"user_id":"2","auth_token":"x"},"result": {"errorcode":"","messages":"Success:Logged On","rstatus":1}}

我希望能夠解析出USER_ID，AUTH_TOKEN ，錯誤代碼，消息，RSTATUS

下面是被調用jQuery代碼：

function authenticate(userName, password) { 
    $.ajax({ 
     url: 'index.php?action=login', 
     type: 'POST', 
     contentType: 'application/x-www-form-urlencoded; charset=UTF-8', 
     data: 'username=' + userName + '&password=' + password, 
     dataType: 'json', 
     async: true, 
     success: function (response) { 
      //i need to parse out the data here 
     } 
    }); 
} 

任何建議，將不勝感激。

Answer 1

如何：

var user_id = response.data.user_id, 
    auth_token = response.data.auth_token, 
    errorcode = response.result.errorcode, 
    messages = response.result.messages, 
    rstatus = response.result.rstatus; 

Answer 2

嘗試像下面，

var user_id = response.data.user_id, 
    auth_token = response.data.auth_token, 
    errorcode = response.result.errorcode, 
    messages = response.result.messages, 
    rstatus = response.result.rstatus;
