Once a user logs in, I set a boolean value to true and intend to update the login button status to display "Logout". Despite attempting to use ng-show, the functionality does not seem to be working properly.
App States:
myApp.config(function ($stateProvider, $urlRouterProvider) {
// default route
$urlRouterProvider.otherwise("/Home");
var header = {
templateUrl: 'commonViews/Header.html',
controller: function ($scope) {
}
};
var footer = {
templateUrl: 'commonViews/Footer.html',
controller: function ($scope) {
}
};
// ui router states
$stateProvider
.state('Home', {
url: "/Home",
views: {
header: header,
content: {
templateUrl: 'views/HomePage.html',
controller: function ($scope) {
}
},
footer: footer
}
})
.state('LoggedIn', {
url: "/LoggedIn",
views: {
'header': header,
'content': {
templateUrl: 'views/LoggedIn.html',
controller: function ($scope) {
}
},
'footer': footer
}
});
});
User Service:
myApp.factory('UserService', function ($http, $localStorage, AuthenticationService) {
return {
logIn: function (email, password) {
return $http.post('rs/loginResource/login', {email: email, password: password})
.then(function (data) {
AuthenticationService.isLogged = true;
alert("Authentication loggedIn inside login controller: " + AuthenticationService.isLogged);
return data;
})
.catch(function (error) {
console.log(error);
});
},
logOut: function () {
if (AuthenticationService.isLogged) {
AuthenticationService.isLogged = false;
delete $localStorage.token;
}
}
};
});
myApp.factory('AuthenticationService', function () {
var auth = {
isLogged: false
};
return auth;
});
Login Controller:
myApp.controller('loginController', ['$scope', '$http', 'jwtHelper', '$localStorage', '$sessionStorage', '$state', '$window', 'UserService', 'AuthenticationService', function ($scope, $http, jwtHelper, $localStorage, $sessionStorage, $state, $window, UserService, AuthenticationService)
{
$scope.token = "";
$scope.$storage = $localStorage;
$scope.loginForm = function (email, password) {
if (email !== undefined && password !== undefined) {
UserService.logIn(email, password).then(function (response) {
$localStorage.token = response.data.token;
if ($localStorage.token) {
$state.go('LoggedIn');
alert("scope loggedIn inside login controller: " + AuthenticationService.isLogged);
}
}).catch(function (status, data) {
console.log(status);
console.log(data);
});
}
$scope.logout = function logout() {
UserService.logOut().success(function () {
$state.go('/');
}).error(function (status, data) {
console.log(status);
console.log(data);
});
};
};
}]);

After a successful login, there seems to be an issue where the status momentarily changes to "Logout" before reverting back to "Login". It's unclear why this is happening. Any insights?
