angular 8 - 按数量过滤对象数组

Question

Is it possible to filter this list where iseidaCcaa.id is equal to a given number:

var centers = [
  {
    id: 2,
    nombre: "Centro 2",
    iseidaCcaa: {
      id: 1,
    },
  },
  {
    id: 3,
    nombre: "Centro 3",
    iseidaCcaa: {
      id: 1,
    },
  },
  {
    id: 1,
    nombre: "Centro 1",
    iseidaCcaa: {
      id: 2,
    },
  },
];

I tried this solution but it is not working

 this.centers = this.centers.filter(element => {
    return element.isiedaCcaa.id == 1;
  })

Answer 1

You have a typo on the return.

should be return element.iseidaCcaa.id == 1

Although I would consider using === if the id is going to be int

Answer 2

You wrong property by type iseidaCcaa not isiedaCcaa

 var centers = [ { "id":2, "nombre":"Centro 2", "iseidaCcaa":{ "id":1, } }, { "id":3, "nombre":"Centro 3", "iseidaCcaa":{ "id":1, } }, { "id":1, "nombre":"Centro 1", "iseidaCcaa":{ "id":2, } } ] var centers = centers.filter(element => { return element.iseidaCcaa.id == 1; }) console.log(centers);
