我的第一個對象是這樣的：

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

我的第二個對象是這樣的：

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

Answer 1

如何動態合並兩個JavaScript對象的屬性？

此方法可以將兩個對象的屬性組合在一起。

Object.assign(obj1, obj2);

或者，如果您要考慮數組，則必須更改數據結構。

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"}

然后你

y.data.push(x)

Answer 2

我們可以使用Object.assign（obj1，obj2）; 合並功能，否則請添加您期望的示例輸出格式

 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)
