Javascript 无法访问json对象中的数据

我是这个平台的新手。所以如果有人能帮我做这件事，那就太好了

---> 我有一个变量globalsyncedinData，其中包含以下json文本格式的数据

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

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

我的代码片段：

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);
     ...
}

在执行时，我会一直收到警报框，直到解析成json对象的字符串为[object]。它就停在那里。我无法访问键值，并且没有在其后面显示警报框，即alertFirst键为：+obj.rows[0]。键；没有开门

我正在android平台上开发一个应用程序，所以我需要一个提醒框。实际上，我需要一个变量，它可以访问globalsyncedinData中的行，这样，我就可以使用$.each对每一行进行迭代。我该怎么做呢？

检查这里的工作小提琴。

你期望发生什么？我正在android平台上开发一个应用程序，所以我需要警报框。实际上，我需要一个变量，它可以访问globalsyncedinData中的行，这样，我就可以使用$.each对每一行进行迭代。我该怎么做呢？如果你是为Android开发的，你可以插入带有USB的手机，并使用你电脑的Chrome控制台进行调试chrome://inspect/devices. 它将比警报方便得多。这样你就知道你的json有什么问题了。是的！它应该会起作用。然而，当我在手机上打开应用程序时，我会得到一个警告框，第一个键是1234；我不明白/它在JSFIDLE中运行良好，但在我的手机中却不行！真奇怪！：/警报“行：”+obj.rows；在我的手机里给了我行：未定义
