如何在JavaScript中組合兩個對象？

Question

我的第一個對象是這樣的：

{id: 1, quantity: 10, address: {id: 2, name: "stamford bridge", city: "london"}} 

我的第二個目的是這樣的：

{data: {id: 2, quantity: 20, address: {id: 4, name: "old traford", city: "manchester"}}, expired: "2017-08-16T06:46:02.566Z"} 

我要將對象

我怎樣才能做到這一點結合？

Answer 1

How can I merge properties of two JavaScript objects dynamically?

這種方法可以在兩個對象的屬性組合在一起。

Object.assign(obj1, obj2); 

或者你必須改變你的數據結構，如果你正在考慮陣列。

var x = {id: 1, quantity: 10, address: {id: 2, name: "stamford bridge", city: "london"}} 

和

var y = {data: [{id: 2, quantity: 20, address: {id: 4, name: "old traford", city: "manchester"}}], expired: "2017-08-16T06:46:02.566Z"} 

然後你

y.data.push(x) 

Answer 2

我們可以使用Object.assign（OBJ1，OBJ2）;功能合併，否則請加你期待

var x={id: 1, quantity: 10, address: {id: 2, name: "stamford bridge", city: "london"}} 
 

 
var y={data: {id: 2, quantity: 20, address: {id: 4, name: "old traford", city: "manchester"}}, expired: "2017-08-16T06:46:02.566Z"} 
 

 
var z = Object.assign(x, y); 
 

 
console.log(z) 
 
console.log(z.id) 
 
console.log(z.data) 
 
console.log(z.data.id)
