Question 162162 in Javascript Question posted in
A very good W3school tutorial can be found here.

How do you filter an array in Javascript with multiple values?

I have this array

var selectedId = [
  "12",
  "22"
];

var allData = [{
    "id": "12",
    "title": "Title 1",
    "description": "description"
  },
  {
    "id": "22",
    "title": "Title 2",
    "description": "description"
  },
  {
    "id": "25",
    "title": "Title 3",
    "description": "description"
  }
]

I want to check for multiple id using filter function

this.allData.filter((people => people.id=='12'));

for single value it is working but i have both 12 and 22 and i want to get only these two records.

Any solution. Thanks

    You can use array.includes()

    const selectedId = [
  "12",
  "22"
];

const allData = [
  {
    "id":"12",
    "title":"Title 1",
    "description":"description"
  },
  {
    "id":"22",
    "title":"Title 2",
    "description":"description"
  },
  {
    "id":"25",
    "title":"Title 3",
    "description":"description"
  }
]

const filtered = allData.filter((people => selectedId.includes(people.id))); 
console.log(filtered);
