Select an object from an array based on a property value

Question

I have an array of objects. Each object has multiple properties such as 'activityType'. I'm trying to assign that object to $scope.selectedActivity based on the $scope.activityType value that is already assigned. I've tried to use $filter but I'm not sure how to code the expression properly.

This is my code:

$scope.selectedActivity = $filter('filter')($scope.activityTypes, $scope.activityTypes.activityType == $scope.activityType);

Try this. Give an object for comparision and set to strict (true). Read $filter for more informations.

$scope.selectedActivity = $filter ('filter')($scope.activityTypes, { 'activityType': $scope.activityType }, true);

@T.J.Crowder it returns all elements which match the criteria in an array.

Okay, asked my question to quickly.

This is how I did it

$scope.selectedActivity = $filter('filter')($scope.activityTypes, { activityType: $scope.activityType} );
