javascript - Watch array changes in AngularJS service -

i have service object exposes array watch changes (within service) , phone call method.

this trivial within controller watching changes array on it's $scope, how can same accomplished in service? service shared in several controllers , don't want implement logic in many places.

i have tried using polymer's arrayobserver, doesn't seem work angular.

does have suggestions? thanks

you can add together watch on $rootscope, i.e.:

.service("mysvc", function($rootscope,...) { var myarray = ... ... $rootscope.$watchcollection( function() { homecoming myarray; }, function(newval) { ... } );

however have careful unregister watch when (if) no longer needed.
