Switching a cookie from JavaScript to AngularJS: A step-by-step guide

Getting a cookie in AngularJS can be done in a more standardized way. Instead of the traditional JavaScript approach, you can implement it using AngularJS code as shown below:


angular.module('myApp', [])
.factory('CookieService', function() {
    return {
        getCookie: function(cname) {
            var name = cname + "=";
            var ca = document.cookie.split(';');
            for (var i = 0; i < ca.length; i++) {
                var c = ca[i].trim();
                if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
            }
            return "";
        }
    };
})
.controller('ModuleCtrl', ['$http', 'CookieService', function($http, CookieService) {
    var self = this;
    self.$http = $http;
    self.CookieID = CookieService.getCookie('Id');

    self.test = function() {
        var params = {
            testId: self.CookieID
        }
    }
}]);

Answer №1

Angular ngCookies

To get started with Angular ngCookies, you first need to include angular-cookies.js in your HTML:

<script src="angular.js">
<script src="angular-cookies.js">

After including the script, add the module as a dependent module of your application like so:

angular.module('app', ['ngCookies']);

Here is an example of how to use ngCookies:

angular.module('cookiesExample', ['ngCookies'])
.controller('ExampleController', ['$cookies', function($cookies) {
  // How to retrieve a cookie
  var favoriteCookie = $cookies.get('myFavorite');
  // How to set a cookie
  $cookies.put('myFavorite', 'oatmeal');
}]);

jQuery

Setting a Cookie with jQuery:

$.cookie("my_cookie", value);

For setting a Cookie with expiration date and path using jQuery:

$.cookie("my_cookie", value, { expires: 1, path: '/' });

Removing a Cookie with jQuery:

$.removeCookie("my_cookie");

Answer №2

Did you have a chance to experiment with $cookies?

If not, another option could be utilizing jQuery cookie instead of AngularJs cookie.

Here's an example showcasing the usage:

angular.module('cookiesExample', ['ngCookies'])
.controller('ExampleController', ['$cookies', function($cookies) {
  // Retrieve a cookie
  var favCookie = $cookies.get('myFavorite');
  // Set a cookie
  $cookies.put('myFavorite', 'chocolate chip');
}]);
