Object.values() (非标准)

This is an experimental technology

Because this technology's specification has not stabilized, check the compatibility
table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The 

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 difference being that a for-in loop enumerates properties in the prototype chain as well).

Syntax

Object.values(obj)

Parameters

obj

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

Description

Object.values()

 returns an array whose elements are strings corresponding to the
enumerable property values found directly upon 

object

. The ordering of the properties
is the same as that given by looping over the property values of the object manually.

Examples

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
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

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.valuesrepositories.
