Angular ng-enter Directive

Just copied it from somewhere to keep for myself .. I mostly put it in the app.js at the bottom so everyone is able to use this function.

.directive('ngEnter', function() {
 return function(scope, element, attrs) {
  element.bind("keydown keypress", function(event) {
   if (event.which === 13) {
    scope.$apply(function() {
     scope.$eval(attrs.ngEnter, {
      'event' : event
     });
    });

    event.preventDefault();
   }
  });
 };
});
