Filter NOT equals in AngularJS

Question

I have a array of objects, in client side. The object in array look like this:

{
    code: 0,
    short_name: 'a',
    type: 1
}

I try to filter this array to 2 arrays:

With type === 1
With type !== 1

I did this:

$scope.array1 = $filter('filter')(data, {type: 1}, true);
$scope.array1 = $filter('filter')(data, {type: !1});

But the not-equal didn't work... what can I do?

Thank you!

Again, if you are just going to filter, use the native method instead:

$scope.array1 = data.filter(x => x.type === 1);
$scope.array2 = data.filter(x => x.type !== 1);

I can't try this, because I can't use in ES6.

@Kutyel , check this fiddle http://jsfiddle.net/U3pVM/33383/ , why last one is not display in list, event last one id is -12 not -1 ??

Hi @chiragsatapara, check the updated fiddle jsfiddle.net/U3pVM/33384, its a more practical example of how to use JS native functions instead of the angular "magic", which seems to be doing a string comparison or something like that (if this helped you please upvote the answer ;)

You're very close. You just need to change your second filter to:

$scope.array2 = $filter('filter')(data, { type: '!1' });

I also renamed the scope variable since otherwise it would just overwrite your first filtered array.

I tried it before but it's didn't work well... because this filter remove also all the object with type that include 1 (like: 12, 13, etc.)

But suppose you are using a key instead of string then just edit above like.. '!' + your_key

For me the given solution { type: '!1' } doesn't work when used with true as last parameter $filter('filter')(data, {type: 1}, true);. However using a function works for me (see angular's doc):

$scope.array2 = $filter('filter')(data, function(value, index, array) {
            return (value.type !== 1);
        }, true);
