Check condition in angularjs

Question

Basically i have a factory

angular.module('app').factory('gService',gService);
function gService($filter, $window) {
    function confirmDialog(message, success, fail) {
        var confirmMessage = navigator.notification.confirm(
                message,
                onConfirm,
                '',
                [$filter('translate')('OK'), $filter('translate')('CANCEL')]
            );
        function onConfirm(index) {         
            return index === 1 ? success() : fail();
        }
        return confirmMessage;
    }
}

I want to check condition outside this factory, if the functions are executed or not

if(gService.confirmDialog.onConfirm){

}

this does not work. How do i check function which is executed in angular?

Answer 1

EMIT & BROADCAST

If you check onConfirm event that it will controll is onConfirm function defined on gService.confirmDialog object where the statement wroten. It is not async and promised job.

if(gService.confirmDialog.onConfirm){

}

You need to notify your listeners first. After that listen that event to do your job.

You can broadcast or emit an event to scopes that waiting for onConfirm event.

   angular.module('app').factory('gService',gService);
    function gService($rootScope, $filter, $window) {
        function confirmDialog(message, success, fail) {
            var confirmMessage = navigator.notification.confirm(
                    message,
                    onConfirm,
                    '',
                    [$filter('translate')('OK'), $filter('translate')('CANCEL')]
                );
            function onConfirm(index) {
                var result = index === 1 ? success() : fail();
                $rootScope.$emit('onConfirm', result); 
                //or
                //$rootScope.$broadcast('onConfirm', result); -> this goes downwards to all child scopes. Emit is upwarded.

            }
            return confirmMessage;
        }
    }

After that you should check if onConfirm event is triggered. This does the controll you need.

function onConfirmFunction( result ){ //You will get the success or fail methods result here... };

$rootScope.$on('onConfirm', onConfirmFunction);

Why don't you do this.

angular.module('app').factory('gService',gService);
function gService($filter, $window) {
    var obj = {
        confirmDialog : confirmDialog,
        onConfirm : onConfirm,
    }
    obj.executed = false;
    function confirmDialog(message, success, fail) {
        var confirmMessage = navigator.notification.confirm(
                message,
                onConfirm,
                '',
                [$filter('translate')('OK'), $filter('translate')('CANCEL')]
            );
        function onConfirm(index) {         
            if(index===1){
                //I dont know you want function or returned value of function but you can use success() as well
                obj.executed = success;
                return success();
            }else{
                obj.executed = fail;
                return fail();
            }
        }
        return confirmMessage;
    }
    return obj;
}

you can check now..

if(gService.executed){

}

and I dont know if you forgot but you haven't returned anything from factory.
