你可以得到你想要的

json.data[0].audience.infomation

请注意，另一个对象被包装在一个数组中。

这是一个JavaScript对象，而不是Java对象。

使用 jquery 库的 $.parseJSON。解析后返回一个 JQuery 对象

要将 JSON 转换为 JavaScript，只需对其进行“评估”。我建议阅读这个简短的教程。

您的 json 结构中有数组，因此您必须像这样访问它们：

 console.log(jsn.data[0].audience[0].information[0].category);

 output is: **Athlete**

这将log the category

在

这是first array item of information

这是first array item of audience

这是first array item of data
