How broadcast data of HTTP post method in angularjs -

i'm using same http method in different controller following sample:

service:

var method="samplemethod"     hotalstatisticservice.getreservations = function (data) {         return $http({             method: 'post',             data: data,             cache: false,             url:'http://sample.com/'+method         });     } 

first controller

.controller("sampleactrl", function ($scope,hotalstatisticservice ) {     hotalstatisticservice.getreservations({start:start, end:end, type:type})         .success(function (data) {          $scope.samplea=data;         }) } 

second controller

.controller("samplebctrl", function ($scope,hotalstatisticservice ) {     hotalstatisticservice.getreservations({start:start, end:end, type:type})             .success(function (data) {              $scope.sampleb=data;             })     } 

how use here method in 1 controller?

let me other solution uses factories better solution.using services option.

another ,perhaps crude way using $rootscope.answer below.

what want share data between 2 controllers. based on reply comments, both controllers belong same module.you can use $rootscope here act common point.

as can see, i've added $rootscope dependency in both controllers , printed txt variable in second div.

js code

var app = angular.module('plunker', []);  app.controller('actrl', function($scope,$rootscope) {   $scope.name = 'this controller ';   $scope.execute = function() {     alert('executed!');   }   $rootscope.txt="hi there other side"; });  app.controller('bctrl', function($scope,$rootscope) {   $scope.name = 'this controller b ';  }); 

html

<div ng-controller="actrl">     <p>hello {{name}}!</p>    </div>     <div ng-controller="bctrl">     <p>hello {{name}}!</p>     {{txt}}   </div>
