javascript - Filter json data in controller, the right way -

(there other questions neither helped me out)

hi, know if right way filter results service i'm displaying 1 result (like detail).

i know use ng-repeat , filter in view , cleanest, want have more control on because re-use of data in controller other operations.

right i'm doing this:

$scope.savedevents = event.getpayedevents(); //gets list service  //goes through entire list , checks match    angular.foreach($scope.savedevents, function(event) {     if (event.idevent == $stateparams.eventid) {         $scope.showevent = event;     } }); //now if there match can use $scope.showevent.eventname etc 

not sure if easier using $filter return 1 event has correct idevent. or if has better solution, please let me know.

thanks

i don't see problems have, inject $filter service , 1 liner:

$scope.showevent = $filter('filter')($scope.savedevents, { idevent: $stateparams.eventid }); 

edit: here easy way resolve result single value returned array:

var showevents = $filter('filter')($scope.savedevents, { idevent: $stateparams.eventid }); $scope.showevent = showevents && showevents.length ? showevents[0] : null; 

in coffeescript little more concise:

$scope.showevent = $filter('filter')($scope.savedevents, { idevent: $stateparams.eventid })?[0]
