Object.values() method returns an array of a given object's own enumerable property values, in the same order as that provided by a for...in loop. (The only difference is that a for...in loop enumerates properties in the prototype chain as well.)

句法

Object.values(obj)
					

参数

obj

The object whose enumerable own property values are to be returned.

返回值

An array containing the given object's own enumerable property values.

描述

Object.values() returns an array whose elements are the enumerable property values found on the object. The ordering of the properties is the same as that given by looping over the property values of the object manually.

Polyfill

To add compatible Object.values support in older environments that do not natively support it, you can find a Polyfill in the tc39/proposal-object-values-entries or in the es-shims/Object.values repositories.

范例

Using Object.values

const obj = { foo: 'bar', baz: 42 };
console.log(Object.values(obj)); // ['bar', 42]
// Array-like object
const arrayLikeObj1 = { 0: 'a', 1: 'b', 2: 'c' };
console.log(Object.values(arrayLikeObj1 )); // ['a', 'b', 'c']
// Array-like object with random key ordering
// When using numeric keys, the values are returned in the keys' numerical order
const arrayLikeObj2 = { 100: 'a', 2: 'b', 7: 'c' };
console.log(Object.values(arrayLikeObj2 )); // ['b', 'c', 'a']
// getFoo is property which isn't enumerable
const 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']
