Mastering the stable usage of $watchIncorporating reliable

Please review the following code snippet:

front_controller

$scope.month=monthNames[$scope.currentmonthnumber];
monthyeartransfer.setvalue($scope.month);

$scope.monthchange = function(m) {
   $scope.month = m;
   monthyeartransfer.setvalue($scope.month);
}

Within this controller, I am updating the month value in the monthyeartransfer service with every click.

The profilecontroller is accessed as shown below:

profilecontroller

$scope.$watch(function(){
   $scope.month = monthyeartransfer.getvalue();
}

However, the above code triggers on every action, even though it should only occur when the month value changes in the service.

I attempted to modify it by:

$scope.$watch('month',function(){
    $scope.month = monthyeartransfer.getvalue();
}

Unfortunately, this approach did not work. How can I achieve this functionality? Thank you!

Answer №1

Here is a method for observing the outcome of a function:

$scope.$watch(function () {
   return monthyeartransfer.getvalue();
}, function (val) {
    // Execute actions...
});
