here we have to check the booking id if booking id and searchValue matched we have to push that object into result array.

let bookingArr = [
  [{
      name: "user 1",
      bookingid: 10,
      product: "ab"
    },
    {
      name: "user 1",
      bookingid: 10,
      product: "cd"
    }
  ],
  [{
      name: "user 2",
      bookingid: 11,
      product: "ui"
    },
    {
      name: "user 1",
      bookingid: 10,
      product: "ef"
    }
  ],
  [{
      name: "user 3",
      bookingid: 12,
      product: "ui"
    },
    {
      name: "user 4",
      bookingid: 13,
      product: "ef"
    }
  ]
];


var searchValue = "10,11";

var FOUND = bookingArr.find(function(post, index) {
  if (post.bookingid == 11)
    return true;
});


console.log(FOUND)

expected result

[ { name:"user 1", bookingid:10, product: "ab" },
    { name:"user 1", bookingid:10, product: "cd" },
    { name:"user 1", bookingid:10, product: "ef" },
    { name:"user 2", bookingid:11, product: "ui" }]

Answer 1

You can try this code:

const bookingArr = [[
  { name: 'user 1', bookingid: 10, product: 'ab' },
  { name: 'user 1', bookingid: 10, product: 'cd' },
], [
  { name: 'user 2', bookingid: 11, product: 'ui' },
  { name: 'user 1', bookingid: 10, product: 'ef' },
],
[
  { name: 'user 3', bookingid: 12, product: 'ui' },
  { name: 'user 4', bookingid: 13, product: 'ef' },
]];


const searchValue = '10,11';

const sv = searchValue.split(',').map(Number);

const FOUND = bookingArr.flat().filter(({ bookingid }) => sv.includes(bookingid));

console.log(FOUND);

Answer 2

You can use Array#filter with a Set for better performance after flattening the array.

let bookingArr = [[
    { name:"user 1", bookingid:10, product: "ab" },
    { name:"user 1", bookingid:10, product: "cd" }
],[
    { name:"user 2", bookingid:11, product: "ui" },
    { name:"user 1", bookingid:10, product: "ef" }
],
[
    { name:"user 3", bookingid:12, product: "ui" },
    { name:"user 4", bookingid:13, product: "ef" }
]];
let searchValue = "10,11";
let set = new Set(searchValue.split(",").map(Number)); // for faster lookup
let res = bookingArr.flat().filter(x => set.has(x.bookingid));
console.log(res);
