【问题描述】：
我有一个用 Python 创建的大型 JSON 对象，我现在需要在网页上显示信息。我的问题是它的大小；里面有嵌套的数组和对象，点处有好几层。我写了一个非常不优雅（而且有问题）的 JavaScript 函数来提取数据，但这对我来说似乎是一个递归问题，不幸的是我不习惯这样思考（还）。
有谁知道解析读取此类对象的好方法？我的目标是真正动态地阅读它，因为我将不得不多次这样做（并且每次对象都会不同，但结构或多或少相同）。 目标是获取这些信息并在网页上有意义地显示它。
如果我可以进一步详细说明，请告诉我。
编辑：这是对象。当我发布这篇文章时，我不在我的电脑旁，而且它相当大。我已经删除了其中可能敏感的部分。我正在使用 JSON2 将其解析为字符串以外的内容。只是大小和嵌套给我带来了问题。

-
嘿@tjsimmons，你能告诉我们你的JSON的结构吗？
-
Does anyone know of a good solution to parsing such an object?显示对象可能会有所帮助。 -
JSON.parse()不工作吗？ -
仅在新浏览器上。如果您希望依赖 JSON，您必须包含 json2.js。

哇伙计..这是一些只有母亲才能爱的 json....
