Filtering array of objects based on value

Question

Is there a way to filter an array of objects by a particular value that could be in any property?

Let\'s say I have this object:

var x = [
    {
                 


        

Answer 1

Well the obvious thing is to combine your for..in loop with your .filter() function:

var x = [{name: "one", swp: "two"}, {name: "two", swp: "three"}, { name: "aa", swp: "bb"}];

var filtered = x.filter(function(v) {
  for (var k in v)
    if (v[k] === "two") return true;
});
console.log(filtered);

Answer 2

use an inner loop method to check individual property values

var val ="one";
var res = x.filter(function(item){
     return Object.keys(item).some(function(prop){
         return item[prop] === val;
     });
});

Answer 3

var arrOfObj = []; // objects you're sifting
var prop = 'whatever';

var matches = arrOfObj.filter(obj => Object.keys(obj).some(k => obj[k] === prop));

You want a combination of Array.prototype.filter and Array.prototype.some which returns a boolean if any of the elements of the array match the condition, it also stops iterating the array (in this case the keys of each object) as soon as it finds a match. If you need cross-browser support (and for some reason aren't using babel) the ES 5 version of the above is

var arrOfObj = []; // objects you're sifting
var prop = 'whatever';

var matches = arrOfObj.filter(function(obj) { 
  return Object.keys(obj).some(function(k) { 
    return obj[k] === prop; 
  });
});
