javascript - AngularJS Load Data from Service -

i having problem getting data service populated view. have service defined such

app.factory('nukeservice', function($rootscope, $http) {     var nukeservice = {};      nukeservice.nuke = {};      //gets list of nuclear weapons     nukeservice.getnukes = function() {         $http.get('nukes/nukes.json')             .success(function(data) {                 nukeservice.nukes = data;             });          return nukeservice.nukes;     };      return nukeservice; }); 

and controller

function navigationctrl($scope, $http, nukeservice){        /*$http.get('nukes/nukes.json').success(function(data) {         $scope.nukes = data;     });*/      $scope.nukes = nukeservice.getnukes();  } 

if use $http.get controller data populates fine, however, if try call data service, nothing. understand query asynchronous having hard time understanding how populate $scope variable once data returned. use $rootscope broadcast event , listen in controller not seem correct way accomplish this. appreciate advice on how correct way.

i think should solve problem

app.factory('nukeservice', function($rootscope, $http) {     var nukeservice = {};      nukeservice.data = {};      //gets list of nuclear weapons     nukeservice.getnukes = function() {         $http.get('nukes/nukes.json')             .success(function(data) {                 nukeservice.data.nukes = data;             });          return nukeservice.data;     };      return nukeservice; });  function navigationctrl($scope, $http, nukeservice){      $scope.data = nukeservice.getnukes();      //then refer nukes list `data.nukes`  } 

this problem object reference.

when calls nukeservice.getnukes() getting reference object a variable $scope.nukes refers memory location.

after remote server call when set nukeservice.nukes = data; not changing object a instead changing nukeservice.nukes referencing object a object b. $scope.nukes not know reassignment , still points object a.

my solution in case pass object a property data , change data property instead of changing reference a
