Function utilizing variables parsed by Angular directive

I am currently working on a directive that I have created:

    feedBackModule.directive("responseCollection", ['deviceDetector', function (deviceDetector) {
    return {
        restrict: "E",
        templateUrl: 'js/modules/Feedback/directives/feedbackResponse/collection.html',
        scope: {
            collections: '=',
            completeCallback: '&'
        },
        link: function (scope, element, attr) {
            scope.endCollection = function () {
                scope.completeCallback(scope.collections);
            }
        }
    };
}]);

In order for this directive to work properly, it needs to interact with the following controller:

feedBackModule.controller('FeedbackResponseController', ['$state', 'Query', 'feedbackSkillService', 'feedbackFactory', 'feedbackResponseService', function ($state, Query, SkillFactory, feedbackFactory, feedbackResponseService) {
    var num_users = null;
    var user_index = 0;
    this.activeUser = null;
    this.final = false;
    this.feedback = feedbackResponseService.getFeedback();

    this.completeUser = function (collections) {
        this.activeUser.start = false;
        if(user_index < (num_users-1)){
            user_index++;
            this.activeUser = this.feedback.feedback_has_target_users[user_index];
        }
        else
        {
            this.final = true;
        }
    }
}]);

For the HTML part of this functionality, you can use the following code:

<response-collection complete-callback="frCTRL.completeUser()" collections="frCTRL.feedback.feedback_collections" ng-if="frCTRL.activeUser.start && !frCTRL.final"></response-collection>

Although the function works correctly, there is an issue with parsing a variable where it turns out to be undefined.

My question now is how I can successfully pass a variable or object to a function in this scenario?

Answer №1

Modify the directive parameter to use =:

successCallback: '='

Update the HTML to call the function (without parentheses):

success-callback="ctrl.successUser"

With these changes, your code will work smoothly.
