<p><code><strong>Object.values()</strong></code>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{{jsxref("Statements/for...in", "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 )。</p>

<h2 id="描述">描述</h2>
<p><code>Object.values()</code>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。</p>
<h2 id="示例">示例</h2>
<pre class="brush: js">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']</pre>

<h2 id="Polyfill">Polyfill </h2>
<p><code>如果要 Object.values</code>兼容不支持它的旧环境，可在 <a href="https://github.com/tc39/proposal-object-values-entries">tc39/proposal-object-values-entries</a> 或 <a href="https://github.com/es-shims/Object.values">es-shims/Object.values</a> 中找到 Polyfill 。</p>
<p>根据<strong>Object.keys()</strong>的Polyfill仿写一个：</p>
<pre class="brush: js">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;
}</pre>
