另一个函数内部的Ionic Call函数（JS服务）

Question

Hey guys so I have the following question : I'm busy with an Ionic mobile app for a project and I need to call a function in another function in one of my services .js Files (pushNotificationService.js)

here is the code :

            checkForNewMessage: function () {
            console.log("This is the regID : " + regID);
            console.log($rootScope.regID);

            var data =
            {
                "action": "push_messages",
                "key": systemKey,
                "data":
                {
                    "action": "checkNewMessages",
                    "device_id": regID,
                    "key": systemKey
                }

            };

            console.log(json_encode(data));
            return $http.post(webserviceURL, json_encode(data))
                .then(function (response) {
                    getMsgNotiLocation(); //this is the function not working
                    return response;
                });
            // getMsgNotiLocation();
        },

EDIT : here is the getMsgNotiLocation():

            getMsgNotiLocation: function () {
            $rootScope.showCounter = true;
            //console.log("This is what gets returned with the regID : " + json_decode(JSON.stringify(window.localStorage.getItem(regID))));
            var theMessagePage = json_decode(window.localStorage.getItem(regID));
            for (var x in theMessagePage) {
                if (theMessagePage[x].read != "true") {
                    console.log("We have gotten this far atleast : " + JSON.stringify(theMessagePage[x].page))
                    if (theMessagePage[x].page === "messages") {
                        $rootScope.afkondigMsgCount = $rootScope.afkondigMsgCount + 1;
                        $rootScope.msgcount = $rootScope.msgcount + 1;
                        console.log(" Afkondigings Message recieved and message count : " + JSON.stringify($rootScope.afkondigMsgCount));
                    }
                    else if (theMessagePage[x].page === "calendar") {
                        $rootScope.kalenderMsgCount = $rootScope.kalenderMsgCount + 1;
                        $rootScope.afkondigMsgCount = $rootScope.afkondigMsgCount + 1;
                        $rootScope.msgcount = $rootScope.msgcount + 1;
                        console.log(" Calendar Message recieved and message count : " + JSON.stringify($rootScope.kalenderMsgCount));
                    }
                    else if (theMessagePage[x].page === "sponsor") {

                        $rootScope.afkondigMsgCount = $rootScope.afkondigMsgCount + 1;

                        $rootScope.msgcount = $rootScope.msgcount + 1;
                        console.log("Besigheidsforum Message recieved and message count : " + JSON.stringify($rootScope.besigheidMsgCount));
                    } else {
                        console.log("Everything failed please recheck the if statements");
                    }

                } else {
                    //The same as if the condition is met but just a - instead of a + 
                }
            }
        },

The other function works 100% (getMsgNotiLocation()) because it gets called elsewhere as well. When I try to execute the app I get the following error : ReferenceError: getMsgNotiLocation is not defined

I just can't figure out how to do this please any help will be appreciated thanks in advance !

Also I know all the comments between the code is bad and stuff but before release I clean my code nicely its just to keep track where I've done what

Answer 1

May be you can trying using arrow function

return $http.post(webserviceURL, json_encode(data))
                .then((response)=> {
                    this.getMsgNotiLocation(); //this is the function not working
                    return response;
                });
