Load message depending on whether you log in or log out

  • 772

I load a message which depends on whether the user logs in or logs out, but there is a problem, that it only shows me the login message in both cases. I use the method backView(), which always gets the view before it is parked. Here is the code:

loading.js

angular.module('loadingPage', ['ionic', 'loginApp', 'historialApp'])
    .controller('mostrarMensaje', mostrarMensaje)
    .factory('obtenerVista', obtenerVista);

mostrarMensaje.$inject = ['$scope', 'obtenerVista'];

function mostrarMensaje($scope, obtenerVista) {

    var vista_Anterior, valor_sesion;

    vista_Anterior = obtenerVista.nombreVista();

    if (vista_Anterior.stateName === "login") {
        $scope.mensaje = "Cargando Informacion";
    } else {
        $scope.mensaje = "Cerrando sesion";
    }

}


obtenerVista.$inject = ['$ionicHistory'];

function obtenerVista($ionicHistory) {

    return {

        nombreVista: function() {

            var vista;
            vista = $ionicHistory.backView();
            return vista;

        }

    };

}

Here is a drawing to be more specific, if something is understood

start/stop message

Thanks in advance for the help.

  1. I use another system that is still easier for you. It is about saving a value in localStorage to know if the user is logged in or not.

    Just add in the login function:

    $window.localStorage.logged = true;

    and in the logout function:

    delete $window.localStorage.logged;

    So when displaying the message:

    function mostrarMensaje($scope, $window) {

    if (!$window.localStorage.logged) {
        $scope.mensaje = "Cargando Información";
    } else {
        $scope.mensaje = "Cerrando sesión";
    }
}

    Well I was able to solve the problem as follows:

    What happened was that loading.js varified what was in window.localStorage.loggedonly once, so it had to be entered multiple times for it to happen

    So to solve it, I made use of view lifecycles, in this case use the event $ionicView.beforeEnter. activates it when entering the page ( load from cache or created for the first time ).

    $scope.$on('$ionicView.beforeEnter', function () {
  if (!$window.localStorage.logged) {
      $scope.mensaje = "Loading Information";
  } else {
      $scope.mensaje = "Closing Session";
  }
});
