Javascript 从对应的键列表中获取 object 值

Question

Hypothetically if we have an object like:

data = {
    a: 3,
    b: 7,
    c: 94,
    d: 854
}

How could I get the values corresponding to a array of keys using vanilla javascript or jQuery? So Something similar to:

var keys = ["a", "d"]
Object.values(data)[keys]

So the output would be an array with the values [3, 854]

Answer 1

You can use map

 const data = { a: 3, b: 7, c: 94, d: 854 } var keys = ["a", "d"] const result = keys.map(rec => data[rec]) console.log(result)
