Angularjs Init Service -


I am working on the AngularJs project in which the top navigation items are loaded using the service call 

  App.service ('menu', function ($ http) {return: function: callback} {$ http.get ('api / menu.json'). Success (function (menu data) {callback (menuData);});}}});   
 I am using the same as described in my  BaseController   
  App.controller ('BaseCtrl' , Function ($ scope, menu) {$ scope.menuData = {}; Menu.get (function (menu data) {$ scope.menuData = menuData;})}}   
 My The menu remains empty for a period of time until the service call is successful and see before you assign any method before assigning the value of  $ scope.menuData .  
 Please tell me, I would like to do everything possible You may have tried, but nothing worked: ( 
 PS: I am using AngularJS v1.2.9  
 
 
 Return a promise from your service, and use it in your controller's resolution:  
  app.service ('menu', function ($ http) {var menuData = null; var promise = $ http.get ('api / menu.json'). Success (function (data) {menuData = data;}); return {getMenuPromise: promise, getMenuData: function () {return menuData;}};});   
 And in your router definitions:  
  $ routeProvider Resolve: {'menuData': function (menu) {return Menu.getMenuPromise;}}}) when the ('/ home', {administrator: 'basckton', template url: '../http; home page')  < / pre> 
 Now when  BaseCtrl  is on, the data is there:  
  app.controller ('BaseCtrl', function ($ radius, menu) {$ scope.menuData = MyService.getMenuData ();});

In brief, the wrapper module is inserted during posting and the status of an entry is changed to 'modified' .
