jQuery中的Object.values() [英] Object.values() in jQuery

问题描述

prototypeJS库具有Object.values()方法，该方法返回对象中的值数组.

The prototypeJS library has a method Object.values() which returns an array of values in an object.

EG:

 var myObj = {
   "key1" : "val1"
   "key2" : "val2"
 }
 Object.values(myObj) //returns ["val1", "val2"]

有没有做相同事情的jQuery方法?

is there a jQuery method that does the same thing?

推荐答案

使用ES6，您可以执行以下操作:

Using ES6, you can do the following:

Object.values = x =>
        Object.keys(x).reduce((y, z) =>
            y.push(x[z]) && y, []);

这只是返回一个包含对象值的数组.不需要JQuery，_或其他任何东西.

This simply returns an array containing the object's values. No need for JQuery, _ or anything else.

注释: Object.values()当前正处于ES7的草案中

note: Object.values() is currently in draft for ES7

使用babel进行安装

Using babel, installing

• babel-preset-es2017
• babel-plugin-transform-runtime

提供对Object.values/Object.entries以及其他ES2017功能的支持.

gives support for Object.values/Object.entries as well as other ES2017 functionality.

根据模块的建议，使用以下内容配置.babelrc文件:

As per recommendation by the modules, configure the .babelrc file with the following:

{
  "plugins": ["transform-runtime"],
  "presets": ["es2017"]
}
