方法一：Object.assign
函数定义
Object.assign(target: object, ...sources: any[]): any;
可以合并多个对象到一个对象中, 返回target
注意：target 对象会被修改
使用示例
'use strict' var obj1 = {name: "Tom", age: 23}; var obj2 = {name: "Tom", age: 24}; var obj3 = {sex: "Man"}; var obj4 = Object.assign(obj1, obj2, obj3); console.log(obj1); // { name: 'Tom', age: 24, sex: 'Man' } console.log(obj2); // { name: 'Tom', age: 24 } console.log(obj3); // { sex: 'Man' } console.log(obj4); // { name: 'Tom', age: 24, sex: 'Man' }
方法二 展开语法
var obj1 = {name: "Tom", age: 23}; var obj2 = {name: "Tom", age: 24}; var obj = {sex: "Man", ...obj1, ...obj2} console.log(obj); // { sex: 'Man', name: 'Tom', age: 24 }
