AngularJS First in array after Filter

Question

In my controller I can call:

$scope.games[0];

To access the first item in my games array. Is there a way to do this keeping Filters in mind.

For example I have:

filter:search

On my repeat, how can I call $scope.list[0]; to equal the first search result?

This has been answered, thank you. I built a cool widget using AngluarJs for Lagged.com, play free online games here: https://lagged.com/

This can be done by injecting the filter's dependency into a controller and calling it in code like

var filteredArray = filterDependency(arrayToFilter,args);

which returns a new, filtered array. Since you are using the "filter" filter (it's a filter whose name is filter), the dependency injection should be filterFilter. Your controller should look something like this:

var app = angular.module('myapp',[]);
app.controller('ctrlParent',function($scope,filterFilter){
    var filteredArray = [];
    $scope.list = ["abc","def","ghi","abcdefghi"];
    $scope.$watch('search',function(newValue){
       filteredArray = filterFilter($scope.list, newValue);
       // do something with the first result
       console.log(filteredArray[0]); // first result
    });    
});

What we're doing is setting a watch on the input model (search) so we can get the new value and re-filter the array any time the input is changed.

Also:

If you need to access the ng-repeat index from within the view, you can use the special property $index inside of the ng-repeat like:

<div ng-repeat="item in list | filter:search">
    {{$index}}
</div>

You can also use $first, $middle, and $last as shown in this Angular doc.
