如何在数组中的对象内添加项目？

我的数组(res.users):

{userName: "name", email: "email@email.com"}

我想要:

{userName: "name", email: "email@email.com", access: "admin"}

我尝试过:

array.push(Object.assign(res.users, {'access': 'admin' }))

我的返回:

[
    {userName: "name", email: "email@email.com"},
    access: 'admin'
]

演示:

const res = {userName: "name", email: "email@email.com"}, array = [];
array.push(Object.assign(res, {'access': 'admin'}))
console.log( array )

编辑:res.users是一个数组，我写错了

Answer 1

只需使用obj.access =“admin”:

let obj = {userName: "name", email: "email@email.com"}

obj.access = "admin"

console.log(obj)
