Say I have the following array:

var x = [{letter: 'A', number: 1}, {letter: 'B', number: 2}, {letter: 'C', number: 3}]

And I want to filter using this array:

var f = ['A', 'B']

So that my resulting array looks like this:

[{letter: 'A', number: 1}, {letter: 'B', number: 2}]

How can I accomplish this using javascript in AngularJS? I tried this, but no luck:

$filter('filter')(x, {letter: f});

If you would like to use AngularJS's Filter module then you can do the following:

var x = [{letter: 'A', number: 1}, {letter: 'B', number: 2}, {letter: 'C', number: 3}]

var f = ['A', 'B']

function filterExp(value,index) {
  return (f.indexOf(value.letter) > -1)
}

$scope.filtered = $filter('filter')(x, filterExp, true);

I have created a JSFiddle to demonstrate its result.

You can do:

var filteredElems = x.filter(function(obj) {
    return f.indexOf(obj.letter) > -1
});
