Question

I know this question has been asked several times, but I'm not understanding if I missed anything or it's just a server thing. I need to show you my code for checking please:

(function(){

var app = angular.module('c4s', ['ionic', 'starter.controllers', 'starter.services']);

app.controller('curiousCtrl', function($http, $scope){
    $scope.stories = [];

    $http.jsonp('http://curious4science.com/?json=1&callback=JSON_CALLBACK')

        .success(function(response) {
            angular.forEach(response.data.children, function(child){
                console.log(response);
                $scope.stories.push(child.data);
            });
        });
});

app.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {

    if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
    }
    if (window.StatusBar) {
      // org.apache.cordova.statusbar required
      StatusBar.styleLightContent();
    }
  });
})

.config(function($httpProvider, $stateProvider, $urlRouterProvider) {
        delete $httpProvider.defaults.headers.common['X-Requested-With'];
        $stateProvider

      // setup an abstract state for the tabs directive
        .state('tab', {
        url: "/tab",
        abstract: true,
        templateUrl: "templates/tabs.html"
  })

  // Each tab has its own nav history stack:

  .state('tab.dash', {
    url: '/dash',
    views: {
      'tab-dash': {
        templateUrl: 'templates/tab-dash.html',
        controller: 'DashCtrl'
      }
    }
  })

  .state('tab.chats', {
      url: '/chats',
      views: {
        'tab-chats': {
          templateUrl: 'templates/tab-chats.html',
          controller: 'ChatsCtrl'
        }
      }
    })
    .state('tab.chat-detail', {
      url: '/chats/:chatId',
      views: {
        'tab-chats': {
          templateUrl: 'templates/chat-detail.html',
          controller: 'ChatDetailCtrl'
        }
      }
    })

  .state('tab.account', {
    url: '/account',
    views: {
      'tab-account': {
        templateUrl: 'templates/tab-account.html',
        controller: 'AccountCtrl'
      }
    }
  });

  // if none of the above states are matched, use this as the fallback
  $urlRouterProvider.otherwise('/tab/dash');

});
}());

And I'm getting this error:

TypeError: response.data is undefined

First, I tried $http.get(....) but I got the error that cross domain thing is not allowed. Then I tried jsop.

Thank you.

The sucess() callback doesn't take the http response as argument. It takes the response data, then the status, then the headers, then the config.

So the code should be

$http.jsonp('http://curious4science.com/?json=1&callback=JSON_CALLBACK')
    .success(function(data) {
        angular.forEach(data.children, function(child){
            console.log(response);
            $scope.stories.push(child.data);
        });
    });

(assuming the returned JSON has a children field which is an array, and that each child has a data field, of course).

Did I miss anything with this $http.jsonp in angularjs?
