递归转换对象到数组

function is_object(mixed_var) {
    if (mixed_var instanceof Array) {
        return false;
    } else {
        return (mixed_var !== null) && (typeof( mixed_var ) == 'object');
    }
}


function objectToArray(obj) {
    var array = [], tempObject;
    for (var key in obj) {

        tempObject = obj[key];

        if (is_object(obj[key])) {
            tempObject = objectToArray(obj[key]);
        }
        array[key] = tempObject;
    }
    return array;
}

或者你可以使用Object.assign():

Const obj = {0: 1,1: 2,2: 3}; const arr =对象。分配([],obj); console.log (arr) // arr是[1,2,3]

如果你正在使用lodash，它可以像这样简单:

var arr = _.values(obj);

使用对象。key和array# map方法。

Var obj = { “1”:5 “2”:7, “3”:0, “4”:0, “5”:0, “6”:0, “7”:0, “8”:0, “9”:0, “10”:0, “十一”:0, “12”:0 }; //获取所有对象属性名 var res = Object.keys(obj) //遍历它们并生成数组 . map(函数(k) { //生成数组元素 返回[+k, obj[k]]; })； console.log (res);

const persons = { 
    john: { age: 23, year:2010},
    jack: { age: 22, year:2011},
    jenny: { age: 21, year:2012}
}
const resultArray = Object.keys(persons).map(index => {
    let person = persons[index];
    return person;
});

//use this for not indexed object to change array

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]]
});
