How to filter array when object key value is in array

by

You can do it with Array.prototype.filter(),

var data = { records : [{ "empid": 1, "fname": "X", "lname": "Y" }, { "empid": 2, "fname": "A", "lname": "Y" }, { "empid": 3, "fname": "B", "lname": "Y" }, { "empid": 4, "fname": "C", "lname": "Y" }, { "empid": 5, "fname": "C", "lname": "Y" }] }
var empIds = [1,4,5]
var filteredArray = data.records.filter(function(itm){
  return empIds.indexOf(itm.empid) > -1;
});

filteredArray = { records : filteredArray };

If​ the ​callBack​ returns a ​true​ value, then the ​itm​ passed to that particular callBack will be filtered out. You can read more about it here.​​​​​​
