数组 – 打字稿从对象中选择ID [复制]

@H_262_4@ 参见英文答案 > From an array of objects,extract value of a property as array                                    13个
我是Typescript的新手.我想从observable中选择id

这是我的观察

let myObj = [{
  "id": 1,"text": "Mary"
},{
  "id": 2,"text": "Nancy"
},{
  "id": 3,"text": "Paul"
},{
  "id": 4,"text": "Cheryl"
},{
  "id": 5,"text": "Frances"
}]

预期结果 ：

let SELEctedIds = [1,2,3,4,5];

我可以在不创建数组并在for循环中推送id的情况下执行此操作.

const myObj = [{"id":1,"text":"Mary"},{"id":2,"text":"Nancy"},{"id":3,"text":"Paul"},{"id":4,"text":"Cheryl"},{"id":5,"text":"Frances"}];

const SELEctedIds = myObj.map(({ id }) => id);

console.log(SELEctedIds);
