Question

我是这个平台的新手。如果有人能帮助我，那真的很棒。

- - - - ＆GT; 我有一个变量globalsyncedinData，其中包含json文本格式的以下数据。

{
    "rows": [
        {

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

我的代码段：

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);
     ...
}

执行时，我收到警告框，直到“解析为json对象的字符串为[object Object]”。它停在那里。我无法访问键值，我没有得到它后面的警告框，即警报（“第一个键是：”+ obj.rows [0] .key）;没有开放。

我在Android平台上开发应用程序，所以我需要警报框。我实际上想要一个可以访问globalsyncedinData中的“行”的变量，这样我就可以使用$ .each（）迭代每一行。我怎么能这样做？
