Question

我有一个这样的对象：

{
            "ABC":{"minValue":0,"maxValue":5},
            "XYZ":{"minValue":0,"maxValue":5},
            "PQR":{"minValue":0,"maxValue":5},
            "overall":{"minValue":0,"maxValue":5}
}

我正在尝试制作一个像这样的简单数组

[
            ["type":"ABC","minValue":0,"maxValue":5],
            ["type":"XYZ","minValue":0,"maxValue":5],
            ["type":"PQR","minValue":0,"maxValue":5],
            ["type":"overall","minValue":0,"maxValue":5]
]

不知道如何获得它。

这是我的尝试：

var s = scoreFilters;  //my json object
    var out = Object.keys(s).map(function(data){
        console.log(data)
        return [["type":data,"minValue":data.minValue,"maxValue":data.maxValue]];
    });

Answer 1

您可以像这样使用Object.entries，map和spread syntax：

let input = {"ABC":{"minValue":0,"maxValue":5},"XYZ":{"minValue":0,"maxValue":5},"PQR":{"minValue":0,"maxValue":5},"overall":{"minValue":0,"maxValue":5}}

let output = Object.entries(input).map(([type, values]) => ({ type, ...values}))

console.log(output)

Answer 2

假设您想要输出一个对象数组，则可以.map Object.entries输入：

const obj = {
  "ABC":{"minValue":0,"maxValue":5},
  "XYZ":{"minValue":0,"maxValue":5},
  "PQR":{"minValue":0,"maxValue":5},
  "overall":{"minValue":0,"maxValue":5}
};
const arr = Object.entries(obj).map(([type, { minValue, maxValue }]) => ({
  type,
  minValue,
  maxValue
}));
console.log(arr);

Answer 3

您可以使用Object.entries()和.map()来获取对象数组：

const data = {
  "ABC": {"minValue": 0,"maxValue": 5},
  "XYZ": {"minValue": 0,"maxValue": 5},
  "PQR": {"minValue": 0,"maxValue": 5},
  "overall": {"minValue": 0,"maxValue": 5}
};

const result = Object.entries(data)
                     .map(([ k, v ]) => Object.assign({}, {type: k},  v));
                     
console.log(result);
