How to share the $scope variable of one controller with another in AngularJS?


I have this:

app.controller('foo1', function ($scope) {
  $scope.bar = 'foo';
});
app.controller('foo2', function ($scope) {
  // want to access the $scope of foo1 here, to access bar
});

How would I accomplish this?


Solution

  • You could use an Angular Service to share variable acrosss multiple controllers.

    angular.module('myApp', [])
    .service('User', function () {
        return {};
    })
    

    To share the data among independent controllers, Services can be used. Create a service with the data model that needs to be shared. Inject the service in the respective controllers.

    function ControllerA($scope, User) {
        $scope.user = User;
        $scope.user.firstname = "Vinoth";
    }
    
    function ControllerB($scope, User) {
        $scope.user = User;
        $scope.user.lastname = "Babu";        
    }
