`Object.values()`方法返回一个给定对象自身的所有可枚举属性值的数组，值的顺序与使用`for...in`循环的顺序相同 ( 区别在于 for-in 循环枚举原型链中的属性 )。

## 语法

    Object.values(obj)

### 参数

`obj`
  被返回可枚举属性值的对象。

### 返回值

一个包含对象自身的所有可枚举属性值的数组。

## 描述

`Object.values()`返回一个数组，其元素是在对象上找到的可枚举属性值。属性的顺序与通过手动循环对象的属性值所给出的顺序相同。

## 示例

    var obj = { foo: 'bar', baz: 42 };
    console.log(Object.values(obj)); // ['bar', 42]

    // array like object
    var obj = { 0: 'a', 1: 'b', 2: 'c' };
    console.log(Object.values(obj)); // ['a', 'b', 'c']

    // array like object with random key ordering
    // when we use numeric keys, the value returned in a numerical order according to the keys
    var an_obj = { 100: 'a', 2: 'b', 7: 'c' };
    console.log(Object.values(an_obj)); // ['b', 'c', 'a']

    // getFoo is property which isn't enumerable
    var my_obj = Object.create({}, { getFoo: { value: function() { return this.foo; } } });
    my_obj.foo = 'bar';
    console.log(Object.values(my_obj)); // ['bar']

    // non-object argument will be coerced to an object
    console.log(Object.values('foo')); // ['f', 'o', 'o']

## Polyfill

`如果要 Object.values`兼容不支持它的旧环境，可在 tc39/proposal-object-values-entries 或 es-shims/Object.values 中找到 Polyfill 。

根据Object.keys()的Polyfill仿写一个：

    if (!Object.values) Object.values = function(obj) {
        if (obj !== Object(obj))
            throw new TypeError('Object.values called on a non-object');
        var val=[],key;
        for (key in obj) {
            if (Object.prototype.hasOwnProperty.call(obj,key)) {
                val.push(obj[key]);
            }
        }
        return val;
    }
