将两个javascript对象合并为一个? [英] Merging two javascript objects into one?

问题描述

我正在尝试将以下对象合并为一个，但是到目前为止还算运气不佳-其结构如下:console.log:

I am trying to merge the following objects into one but having no luck so far - the structure is as follows in my console.log :

    2018-05-11 : {posts: 2} // var posts
    2018-05-11 : {notes: 1} // var notes

一旦合并，我希望它看起来像下面的

Once merged I want it to look like the following

2018-05-11 : {posts: 2, notes: 1}

我已经尝试过object.assign()，但是它只是删除初始帖子数据-最好的方法是什么?

I have tried object.assign() but it is just removing the initial posts data - what is the best approach for this?

推荐答案

这是一个更通用的函数.它会传播通过对象，并将合并为声明的变量.

Here's a function that's a bit more generic. It propagates through the object and will merge into a declared variable.

const posts = {  '2018-05-11': {    posts: 2  },  '2018-05-12': {    posts: 5  }};
const notes = {  '2018-05-11': {    notes: 1  },  '2018-05-12': {    notes: 3  }};

function objCombine(obj, variable) {
  for (let key of Object.keys(obj)) {
    if (!variable[key]) variable[key] = {};

    for (let innerKey of Object.keys(obj[key]))
      variable[key][innerKey] = obj[key][innerKey];
  }
}

let combined = {};
objCombine(posts, combined);
objCombine(notes, combined);
console.log(combined)
