我有一个对象数组:
const ObjArray= [{
"id": "90e17e10-8f19-4580-98a8-ad05f4ecd988",
"name": "john",
"description": "worker",
"place": "f.1.1",
...
},
{
"id": "90e17e10-8eqw-4sdagfr4ecd9fsdfs",
"name": "joe",
"description": "dev",
"stepType": "d.2.1",
...
}
];
我想过滤上面的对象数组,以仅返回对象的特定属性。
比方说,我只想返回新数组中每个对象的ID和名称,如下所示:
[{
"id": "90e17e10-8f19-4580-98a8-ad05f4ecd988",
"name": "john"},
{
"id": "90e17e10-8eqw-4sdagfr4ecd9fsdfs",
"name": "joe" }
我对此进行了搜索,但找不到如何以自己想要的方式获得它。

恕我直言,您正在使用Array#map
寻找类似的内容:
ObjArray= [{
"id": "90e17e10-8f19-4580-98a8-ad05f4ecd988",
"name": "john",
"description": "worker",
"place": "f.1.1" },
{
"id": "90e17e10-8eqw-4sdagfr4ecd9fsdfs",
"name": "joe",
"description": "dev",
"stepType": "d.2.1",}
];
console.log(ObjArray.map(o => ({'id': o['id'], 'name': o['name']})));
如果您喜欢object destructuring
:
ObjArray= [{
"id": "90e17e10-8f19-4580-98a8-ad05f4ecd988",
"name": "john",
"description": "worker",
"place": "f.1.1" },
{
"id": "90e17e10-8eqw-4sdagfr4ecd9fsdfs",
"name": "joe",
"description": "dev",
"stepType": "d.2.1",}
];
console.log(ObjArray.map(({id, name}) => ({id, name})));
