angularjs - How to get the data for my controller when http request in progress? -

i have following controller

1) introctrl

2) articlectrl

3) articleservice (service)

now sending http request introcrtl

 .controller('introctrl', function($scope, articleservice) {      articleservice.getarticles(); }); 

and ariclectrl

  .controller('articlectrl', function($scope,$rootscope,articleservice) {    $scope.articles = articleservice.fetcharticles(); }) 

and service is

.service('articleservice', function ($http, $q) {  var articlelist = [];         var getarticles = function() {                 $http({                     url: "muylink,co,",                     data: { starlimit: 0, endlimit: 150,created_date: 0 },                     method: 'post',                     withcredentials: true,                 }).success(function (data, status, headers, config) {                     articlelist.push(data);                  }).error(function (err) {                     console.log(err);                 })             };          var fetcharticles = function() {                 return articlelist[0];             }              return {                 getarticles: getarticles,                 fetcharticles: fetcharticles             };    }); 

which working fine. problem that

sometimes http request sending respone late , got nothing in

$scope.articles.

can implement watch here. how need implement $watch here. dont want implement promise. because want run http request behind scene.

thanks

it better if switch state based setup ui-router way can :

$stateprovider.state('mystate', {       url: 'the/url/you/want',       resolve:{          articleservice: 'articleservice' // dependency injecting here,          articles: function (articleservice) {              return articleservice.getarticles.$promise;          }        },        controller: 'introctrl'    })  // controller can inject articles , resolved before controller loads fetched prior  .controller('introctrl', function($scope, articles) {      $scope.articles = articles; }); 

for more information take @
