在JavaScript对象中找到的属性名称的表单数组 [英] Form array of property names found in a JavaScript Object

问题描述

我有以下对象

var columns = {ContributionType: "Employer Contribution",
               Employee1: "0",
               Employee2: "0",
               Employee3: "0"
              };

由此，我需要像下面这样单独用它们的属性键形成一个数组

From this I need to form an array with they property keys alone like following

var keys=["ContributionType", "Employee1", "Employee2", "Employee3"];

属性数量是动态的

问题: 如何使用lodash或纯JavaScript实现此目标?

推荐答案

Object.keys()

var columns = {ContributionType: "Employer Contribution",
               Employee1: "0",
               Employee2: "0",
               Employee3: "0"
              };
var keys = Object.keys(columns);
console.log(keys);
