Answer 1

• Inject $filter to your controller

• Then wherever you want to use filter,

  $filter('filtername');

In your case you have to use the built-in filter filter .

$filter('filter')($scope.aciveresults,{status:true})

Fiddle

OR you can also invoke the filter by filter name plus the Filter suffix. So,

function MyCtrl($scope,filterFilter){
   filterFilter($scope.aciveresults,{status:true})
}

Answer 2

if you want to use filter in javascript do it this way

$scope.aciveresults = $filter('filter')(data, {status: true}, [true/false for strict mode])

Answer 3

You should probably do this in your ng-repeat, like so:

 ng-repeat="items in data | filter:item.status == true"

since, most probably, data.status doesn't exist, data is a set of objects, each having a status key / value pair.

Answer 4

var resultArray = $filter('filter')($scope.aciveresults , {status:true} );

syntax: $filter('filter')(array, expression, comparator)
