Angularjs - multiple tabs in same browser

Navigation
2

I'm using angularJS in my Node application. When I try to open another tab also with my application in the same browser (or open another instance of the same browser) I get this error: 

s:1 Uncaught SyntaxError: Unexpected token u in JSON at position 0(anonymous function) @ utils.js:14
angular.js:13236 SyntaxError: Unexpected token u in JSON at position 0

In my script utils.js on line 14 has the following command: 

var param = JSON.parse(window.sessionStorage.param);

I know it's very generic, but I'm a newbie in WEB development and I'm posting this hope that someone has had the same problem (or something similar) and can guide me! I have no idea where to start looking for a solution, so I posted it too.

If necessary, I can add some information that is relevant and I have not put it here.

Thank you in advance!

sessionStorage belongs exclusively to the browser session, which is linked to the page.

If you want to share content between two or more tabs / windows, use localStorage .

Implementation example: 

app.factory('userService', ['$rootScope', function ($rootScope) {
    var service = {
        model: {
            name: '',
            email: ''
        },

        SaveState: function () {
            sessionStorage.userService = angular.toJson(service.model);
        },

        RestoreState: function () {
            service.model = angular.fromJson(sessionStorage.userService);
        }
    }

    $rootScope.$on("savestate", service.SaveState);
    $rootScope.$on("restorestate", service.RestoreState);

    return service;
}]);
