JavaScript 或 Ruby。重新格式化 JSON 对象

Question

我需要转换这个 JSON 对象:

[
    [
        "email@email.com"
    ],
    [
        "email2@email.com"
    ],
    [
        "email3@email.com"
    ],
    [
        "email4@email.com"
    ]
]

进入此:

{
    "data": [
        {
            "email": "email@email.com"
        },
        {
            "email": "email2@email.com"
        },
        {
            "email": "email3@email.com"
        },
        {
            "email": "email4@email.com"
        }
] }

这是如何完成的？

Answer 1

嗯，这实际上只是一个数组的数组，但这不是重点。只需循环数组数组并将相关数据推送到对象中的新数组即可:

var my_new_object = {};
my_new_object['data'] = [];

for (var i = 0; i < your_array.length; i++) {
  my_new_object.data.push({"email": your_array[i][0]});
}
