Answer 1

如何动态合并两个JavaScript对象的属性？

此方法可以将两个对象的属性组合在一起。

Object.assign(obj1, obj2);

或者，如果您要考虑数组，则必须更改数据结构。

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

我们可以使用Object.assign（obj1，obj2）; 合并功能，否则请添加您期望的示例输出格式

 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)
