Question

在我上次升级后，我尝试启动我的应用，在应用中使用时出现了很多错误。

这是我更新项目后的错误之一（在登录时，我在几个不同的函数中有许多未定义的）：

Error: updateUserDetails is not defined

此外，当我尝试使用Facebook登录时：

ionic.bundle.js:26794 ReferenceError: facebookConnectPlugin is not defined
    at Object.login (ng-cordova.js:2190)
    at Object.login (facebookService.js:35)

    at defaultHandlerWrapper (ionic.bundle.js:16787)
    at HTMLButtonElement.eventHandler (ionic.bundle.js:16775)

以下是updateUserDetails页面：

 angular.module('starter.controllers',[])
        .controller('loginCtrl', function($scope, $rootScope,  $state, $fbHelper, $ionicLoading, $uiHelper, $api, $ionicHistory, $parsePush) {

            $scope.user = {
                email: "",
                password: ""
            };

            function handleInputError(emailVal, passwordVal){
                var errorMsg = '';
                if(!emailVal){
                    errorMsg = 'Please insert a valid email address';
                } else if(!passwordVal) {
                    errorMsg = 'Please insert your password';
                }
                if(errorMsg) {
                    $uiHelper.popError("", errorMsg,  function(){});
                }
            }

            function goToFeed(){
                $state.go('app.feeds.latest', {type: "getLatestQuestions", reload: true});
            }

    ...

        })


        .controller('registerCtrl', function ($scope, $rootScope,  $state, $ionicLoading, $uiHelper, $api, $ionicHistory, $parsePush) {
            console.log("init registerCtrl");

            $scope.user = {
                email: "",
                nickname: "",
                password: "",
                verify: "",
                gender: "m"
            };

            $scope.register = function($event){
                $event.target.blur();

                var emailVal = $scope.user.email,
                    nicknameVal = $scope.user.nickname,
                    passwordVal = $scope.user.password,
                    verifyVal = $scope.user.verify,
                    genderVal = $scope.user.gender;

                if(!emailVal || !passwordVal ||  !nicknameVal || !verifyVal || !genderVal || passwordVal!= verifyVal  ){
                    handleInputError(passwordVal, verifyVal);
                    return;
                }

                $ionicLoading.show();
                $api.register(emailVal, nicknameVal, passwordVal, genderVal).then(function(data){
                    if(data && data.error){
                        $uiHelper.popError("", data.error, function(){});
                    } else if(data && data._id){
                        updateUserDetails(data.user); //ERROR IS HERE
                        $ionicHistory.nextViewOptions({disableBack: true});
                        $parsePush.initParseNotifications();
                    }

                });
            }
        });

Answer 1

试试这个：

var updateUserDetails = function(data){
  $rootScope.$broadcast('user:updated',{
    userId : data._id, 
    userPicture: data.picture, 
    userName: data.name, 
    gender: data.gender
  });
}

updateUserDetails(data.user);

Answer 2

您似乎正在调用此行

updateUserDetails(data.user); //Error in this line

寄存器中的

。该函数看起来像是在loginCtrl函数中定义的（我无法确定，因为您从示例中省略了相当多的代码）。如果这是您尝试从多个控制器调用的函数，则应该考虑在服务中定义它并将该服务注入需要它的控制器中。

像这样：

.factory('User', function($rootScope){
    return {
        updateUserDetails:  function(data){
        $rootScope.$broadcast('user:updated',{userId : data._id, userPicture: data.picture, userName: data.name, gender: data.gender});
    }
}

您需要确保在服务中有对用户的引用，但希望这可以帮助您入门。
