Невозможно получить доступ к данным в объекте json

Question

Я новичок в этой платформе. Это было бы здорово, если бы кто-нибудь мог мне помочь.

-----> У меня есть переменная globalsyncedinData, которая имеет следующие данные в текстовом формате json.

{ 
    "rows": [ 
     { 
      "key": "1234", 
      "id": "1234", 
      "value": {

      } 
     } 
    ], 
    "total_rows": 4, 
    "update_seq": 10 
} 

Мой фрагмент кода:

function setsyncUserDetails(tx) { 

    alert("globalsyncedinData: "+window.globalsyncedinData); 
    alert('into setsyncUserDetails method'); 
    var obj = JSON.parse(window.globalsyncedinData); 
    alert('parsed string into json object is:'+obj); 
    alert("First key is:"+ obj.rows[0].key); 
    ... 
} 

При выполнении, я получаю окно предупреждения до "разобран строку в объект JSON является [объект Object]". И он останавливается. Я не могу получить доступ к ключевым значениям, и я не получаю после него окно предупреждения, т. Е. Предупреждение («Первый ключ:» + obj.rows [0] .key); не открывается.

Я разрабатываю приложение на платформе Android, поэтому мне нужно окно предупреждения. Я действительно хочу переменную, которая может получить доступ к «строкам» из globalsyncedinData, так что я могу использовать $ .each() для итерации по каждой строке. Как я могу это сделать?
