Question

在我看来，曾经看到过比这更短的解决方案：

let obj = { id: 12345, name: "Some name", desc: "Description" }

someFunction(id, name, desc) {
  obj.id = id;
  obj.name= name;
  obj.desc= desc;
}

有人可以告诉我是否有更快的方法来分配具有相同名称的新值？

Answer 1

我认为您正在寻找Object.assign()：

＆＃13;

let obj = {id: 12345, name: 'Some name', desc: 'Description'}
Object.assign(obj, {id: 54321})
console.log(obj) // {id: 54321, name: 'Some name', desc: 'Description'}
Object.assign(obj, {id: 123, name: 'Some other name', desc: 'New description'})
console.log(obj) // {id: 123, name: 'Some other name', desc: 'New description'}

＆＃13;

Answer 2

你指的是财产简写吗？

let id = '12345';
let name = 'Some name';
let desc = 'Description';

let obj = { id, name, desc };

Answer 3

您可以使用Object.assign：

function someFunction(id, name, desc) {
  Object.assign(obj, {id, name, desc});
}
