Adding score to Angular quiz app

[seannie]

Hi All

I have been following a great tutorial on building a quiz app with angular, link supplied below:

Quiz App

I am trying to expand a bit on this to add scoring at the end of the quiz but I don’t seem to be able to get this functionality working. Here’s an amendment I have tried to make to the code to get a score:

$scope.isCorrect = function (question) {
        
        // inserted declaration and initialisation here

        $scope.score = 0; 

        var result = 'correct';
        
        // inserted if statement in here to check whether score needs to be added after answer check

        if(result == true){ 
        $scope.score++;
        }
        
        question.Options.forEach(function (option, index, array) {
            if (helper.toBool(option.Selected) != option.IsAnswer) {
                result = 'wrong';
                return false;
            }
        });
        
        return result;
    };

It’s only a basic start so I’m probably way off. I only seem to be getting a score of 1 even though I try to increment the score for each correct answer.

I’d be grateful for any help with this to try and get it working.

Thanks for any help.
