angularjs - Unable to update the rootScope in angular -

i trying send request php file 1 controller in angular , getting response. stored response in rootscope variable initialized in controller.run() method 0.

now trying use updated rootscope in controller in order display response php page. rootscope not getting updated , still showing 0.

here code.

the following run method rootscope initialized

admincontroller.run(function ($rootscope) {     $rootscope.n = 0; }); 

the following code controller 1 requesting response php page , updating rootscope variable.

admincontroller.controller('adminlogincontroller', function($scope,$rootscope,$http,$window) {      $scope.logincheck = function(event,user){         var request = $http({             method: "post",             url: "../_/php/logincheck.php",             headers: { 'content-type': 'application/x-www-form-urlencoded'     }         });         request.success(function (data) {             $rootscope.n=data;             $rootscope.$apply();             $window.location.href = 'admin.html#admin_home';                });     } }); 

here code second controller utilizing rootscope variable. here problem comes rootscope not getting updated , displaying me 0 initialized.

admincontroller.controller('adminhomecontroller', function($scope,$rootscope,$http,$window) {     $scope.uname=$rootscope.n;     alert($scope.uname); }); 

can 1 let me know going wrong.

your problem sounds timing issue. communicate between controllers $rootscope, can set event listen changes.

update root scope:

$rootscope.$broadcast('n', data); 

listen changes:

$rootscope.$on('n', function (event, data) {     //do new value 'data' });
