                        console.log(data[0]);
        }
    });

的输出data是

Object
    data: Array[25]
        0: Object
            contentTypes: Array[4]
            creationDate: "2012-05-31T20:21:20.532+0000"
            creator: Object

            __proto__: Object
        1: Object
        2: Object
        3: Object

但是当我尝试输出data[0]或data[1]它们都以undefined. 我不确定如何处理这个 JSON 对象。

的输出alert(data)是

[Object object]

所以我假设它是一个格式正确的 JSON 对象。

这是输出 JSON.stringify(data)

如果您要输出字符串化数据，并且其中有一个名为 data 的数组，那么您需要执行 data.data[0] 而不是 data[0]。

如果您说：

success: function(result, status, xhr){
  var data = result.data;

然后 data[0] 就可以了。
