Hi Pablo,
There is quiet a bot of code but yes they are in nested controllers, here's
some code. Once the update function in controller 2 is done the listlength
variable updates accordingly but the updated value doesn't carry over to
the third controller, why is that?
app.controller("controller1", function($scope){
$scope.list = []; //this gets populated with data from a database
$scope.listLength = $scope.list.length;
});
app.controller("controller2", function($scope){
$scope.$watch('listLength', function(newVal, oldVal){
if($scope.listLength !== newVal) $scope.listLength = newVal;
});
}); //I have watch functions within the controllers like so
app.controller("controller3", function($scope){
$scope.$watch('listLength', function(newVal, oldVal){
if($scope.listLength !== newVal) $scope.listLength = newVal;
});
});
