Troubleshooting AngularJS: Diagnosing Issues with My Watch Functionality

I need to set up a watch on a variable in order to trigger a rest service call whenever its value changes and update the count.

Below is the code snippet I have:

function myController($scope, $http) {

    $scope.abc = abcValueFromOutsideOfMyController;    

    $scope.getAbcCnt= function()
    {
        url2 = baseURL + '/count/' + $scope.abc;

        $http.get(url2).success(function (data) {
            $scope.abcCnt = data.trim();
        });
    };

    $scope.$watch('abc',getAbcCnt);
}

However, an error is being thrown:

ReferenceError: getAbcCnt is not defined

As a beginner in AngularJS, please guide me if there's a basic concept I'm overlooking and whether what I'm trying to achieve is feasible.

The solution mentioned here didn't address my issue AngularJS : Basic $watch not working

Answer №1

Make sure to include it within the $scope object.

$scope.$watch('xyz', $scope.getXyzCount);

If you choose to define your function without using the $scope prefix, your current call will still function properly. However, this approach will prevent you from accessing the function in the view. If there is no need to access the function in the view, you can define it without the $scope and retain your existing $watch statement.

Answer №2

It seems like the intended code snippet is

$scope.$watch('abc',$scope.getAbcCnt);
