[SOLVED] angular ngCookies doesn't save cookies after restarting the browser

angular ngCookies doesn't save cookies after restarting the browser

 var app = angular.module('MyApp', ['ngCookies']);
        app.controller('MyController', function ($scope, $window, $cookies) {
            $scope.WriteCookie = function () {
                $cookies.put("Name", $scope.Name);

            };
            $scope.ReadCookie = function () {
                $window.alert($cookies.get('Name'));
            };
            $scope.RemoveCookie = function () {
                $cookies.remove('Name');
            };
        });

I wrote this simple demp app for cookies in angular.

whenever I enter this (via nodeJS) and go to this url: http://127.0.0.1:8080

the cookies is presisted in the browser's cookies. when I click refresh or close the tab and opening a new tab with this url (without closing the browser) the cookies stays.

However, when I close the browser (chrome/IE/firefox) and open this url again, the cookies is not there!

why? how can I make it like facebook when even if I trun off my computer and start it again it will remember my login info by coockis?

Thanks

Solution

This is because if you don't set an expiration time for the cookie, it will be created as session cookie. Which will be removed as soon as you close the browser.

In order to avoid this just set an expiration time for the cookie, like e.g. here for one day:

var expireDate = new Date(); 
expireDate.setDate(expireDate.getDate() + 1); 

$cookies.put('Name', $scope.Name, {
  expires: expireDate
});
