JS从object中的数组中找到匹配的object

Question

I have an array:

let gid = ['554', '555', '564', '575', '618']

Then I have an object:

let obj = {
  attr1: 'att',
  attr2: 'att2',
  attr3: [
    {
      attr: 'att',
      id: 554,
    },
    {
      attr: 'att',
      id: 555,
    },
    {
      attr: 'att',
      id: 1,
    },
  ],
};

How to I return the values of obj.attr3.id that match the values in gid ?

Answer 1

you should map the attr3 array.

let matches = obj.attr3.map( (item, index) => item.id == gid[index])

Answer 2

Is this what you might be asking for?

obj.attr3.filter((item, index) => item.id == gid[index])
