我有一些应用程序。以下是我从服务器上获得的考试答案（这是一种在线考试方式）。

考试将包含部分和部分将包含问题。给定响应包含2个部分

        },

我正在访问section对象，如下所示：

success: function (msg) {
    resData = msg.Response;
    for (i = 0; i < msg.Response.exam_section_id.length; i++)
    {
        alert(resData.exam_section_id[i]);
        localStorage.setItem(resData.exam_section_id[i],
                             JSON.stringify(resData.exam_section_id[i]));

    }
}

alert(resData.exam_section_id[i]);给出了字符串ID。 如何访问下图中第1部分所示的section对象。 我想以同样的方式访问该部分的问题

alert(resData.exam_section_id[i].section_ques_id[0]);

这里的技巧是，将动态生成对象的名称（这是部分ID和问题ID）。

任何人都可以帮助我了解如何访问这些对象。
