Access JSON file in Angular.js

Question

I want to access json file in angular.js by using the following code but I am unable to access the code because of the below mentioned shown error. Help would be appreciated.!!

module :

angular.module("demoApp", ['demoApp.factory','demoApp.controllers']);

Factory:

angular.module('demoApp.factory', []).
factory('getJsonDataFactory',function($http){
    return{
    getData : function() {
        return $http.get('mapData.json');
    }
 }
});

controller :

angular.module('demoApp.controllers', []).
  controller('GetJsonController', function($scope,$http,getJsonDataFactory) {
              $scope.markers = [];  
              getJsonDataFactory.getData().success(function(data){
                $scope.photos=data;
            });
        });

Error : In firefox:

 "Access to restricted URI denied" code: "1012"


return logFn.apply(console, args)

In Chrome :`

Origin null is not allowed by Access-Control-Allow-Origin.

In fact i think you don't have a server.

So, you're getting your application through the file:// protocol.

But file:// protocol can't do http get methods for security reasons .

To solve your matter i suggest you to put your application on a simple web server (like Apache, or wamp, xamp, lamp etc) or better to use grunt to build your application and run it on a test server through node.js
