Acces data from service in angularjs

Question

I have a service where I pass some data on click what works great, but now I wanna pull that data from the service and add it to a scope in another controller and just log everytime there is something added with the $watch function.

My service:

app.service('infoService', function() {
    var currentInfo = [];
    return this.method = function(data){
        return currentInfo = data;
    };
});

Where I try to pull the data

app.controller('clickController', function($scope, infoService) {
    $scope.data = infoService.method();
    $scope.$watch('data', function(newVal, oldVal) {
        console.log(newVal, oldVal);
    });
});

The only thing I currently see the last hour are errors and errors.

yes ofcourse, it keeps saying that the method is not a function, when I call it in the controller. If I log the data in the service there are no problems whatsover. — Dennis

how could you log the data in the service when you can't call that method in your controller? — murnax

Can you remove the return statement from your service

this.method = function(data){
    return currentInfo = data;
};

then you should be able to call function in your service

hope this helps.

Nope, thought also. But already tried that, doesn't do anything.

Try putting the watch on the return value of the service, like this:

$scope.$watch(function () { return infoService.method(); }, function(newVal, oldVal) {
        console.log(newVal, oldVal);
    });
