使用lodash，除了上面提供的答案外，还可以将键放在输出数组中。

输出数组中没有对象键

for:

const array = _.values(obj);

如果obj为以下内容:

{ “art”: { id: 1,  title: “aaaa” }, “fiction”: { id: 22,  title: “7777”} }

那么数组将是:

[ { id: 1, title: “aaaa” }, { id: 22, title: “7777” } ]

使用输出数组中的对象键

如果你写('genre'是你选择的字符串):

const array= _.map(obj, (val, id) => {
    return { ...val, genre: key };
  });

你会得到:

[ 
  { id: 1, title: “aaaa” , genre: “art”}, 
  { id: 22, title: “7777”, genre: “fiction” }
]

如果你正在使用lodash，它可以像这样简单:

var arr = _.values(obj);

使用for in

var obj = { "10":5, "2":7, "3":0, "4":0, "5":0, "6":0, "7":0,
            "8":0, "9":0, "10":0, "11":0, "12":0 };

var objectToArray = function(obj) {
    var _arr = [];

    for (var key in obj) {
        _arr.push([key, obj[key]]);
    }
    return _arr;
}

console.log(objectToArray(obj));

另一个解决方案是Object。输入不适合你。

const obj = { '1': 29, '2': 42 }; const arr = Array.from（Object.keys（obj）， k=>['${k}'， obj[k]]）; 控制台.log（到达）;

下面是es6使用扩展操作符和Object.entries的“新”方法。

const data = {"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0};

const dataSpread = [...Object.entries(data)];

// data spread value is now:
[
  [ '1', 5 ],  [ '2', 7 ],
  [ '3', 0 ],  [ '4', 0 ],
  [ '5', 0 ],  [ '6', 0 ],
  [ '7', 0 ],  [ '8', 0 ],
  [ '9', 0 ],  [ '10', 0 ],
  [ '11', 0 ], [ '12', 0 ]
]

var obj = { "1": 5, "2": 7, "3": 0, "4": 0, "5": 0, "6": 0, "7": 0, "8": 0, "9": 0, "10": 0, "11": 0, "12": 0 }
let objectKeys = Object.keys(obj);

let answer = objectKeys.map(value => {
    return [value + ':' + obj[value]]
});
