将对象变成对象数组 [英] Turn object into array of objects

问题描述

我正在尝试将此对象转换为对象数组，并将对象键置于数组中每个对象的属性中.

I'm trying to turn this object into an array of objects, with the object key being placed into a property of each of the objects in the array.

以下是输入内容:

var input = {
  "2017-03-13": ["Event 1", "Event 2"],
  "2017-03-14": ["Event 1", "Event 2"],
  "2017-03-15": ["Event 1", "Event 2"]
}

这是我想要的输出:

[
  {
    date: "2017-03-13",
    events: ["Event 1", "Event 2"]
  },
  {
    date: "2017-03-14",
    events: ["Event 1", "Event 2"]
  },
  {
    date: "2017-03-15",
    events: ["Event 1", "Event 2"]
  }
]

关于如何处理此问题的任何想法?我也可以使用underscore.js.

Any thoughts on how I might approach this? I have underscore.js at my disposal as well.

推荐答案

您可以使用Object.keys()和map()来做到这一点.

You can do this with Object.keys() and map().

var input = {
  "2017-03-13": ["Event 1", "Event 2"],
  "2017-03-14": ["Event 1", "Event 2"],
  "2017-03-15": ["Event 1", "Event 2"]
}

var result = Object.keys(input).map(function(e) {
  return {date: e, events: input[e]}
})

console.log(result)

使用ES6，您可以使用箭头功能在一行中完成此操作.

With ES6 you can do this in one line using arrow functions.

var result = Object.keys(input).map(e => ({date: e, events: input[e]}))
