我有一个复杂的嵌套JSON，我试图在我的Javascript代码中解析/读取它，但不确定如何访问这些对象。下面是 JSON 响应：

我想访问"亡魂原版..."并显示它和"暮光之城..."以及主对象中的任何其他数据。还可以访问与每个对象关联的"轨迹"数据。有什么建议吗？

将其粘贴到变量中

var example = { "jsonresponse": { ... } };

然后您可以通过以下方式访问它：

example.jsonresponse;

或

example["jsonresponse"];

您可能还想查看 JSON.parse（） 和 JSON.stringify（） https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/JSON
