Callback when entity returns data - angularjs

How to call callback when Device returns data and pass this to the callback method.
Controller
(function() {
'use strict';
angular
.module('frontendApp')
.controller('DeviceController', DeviceController);
DeviceController.$inject = ['$scope', '$state', 'Device'];
function DeviceController ($scope, $state, Device) {
var vm = this;
vm.devices = [];
loadAll();
function updateMap(flag){
var self = this;//how to pass "this" from loadAll()?
// logic to update map
}
function loadAll() {
Device.query(function(result) {
vm.devices = result;
// Callback function here - updateMap(true)
});
}
}
})();
Service
function Device ($resource, DateUtils) {
var resourceUrl = 'api/devices/:id';
return $resource(resourceUrl, {}, {
'query': { method: 'GET', isArray: true},
'update': { method:'PUT' }
});
}

As discussed, you can use vm directly inside the updateMap function as below.
(function() {
'use strict';
angular
.module('frontendApp')
.controller('DeviceController', DeviceController);
DeviceController.$inject = ['$scope', '$state', 'Device'];
function DeviceController ($scope, $state, Device) {
var vm = this;
vm.devices = [];
loadAll();
function updateMap(flag){
console.log(vm.devices);
}
function loadAll() {
Device.query(function(result) {
vm.devices = result;
// Callback function here - updateMap(true)
});
}
}
})();

Factory Service is always undefined

I've spent a few hours trying to debug this with no real breakthroughs. My console.logs correctly output the load order.
- app
- factory
- controller
I'm annotating my dependencies (even though I'm not minifying at the moment).
Is there anything obviously wrong here that I am missing?
error

(function () {
'use strict';

var app = document.getElementById('InventoryProductApp');
angular.bootstrap(angular.element(app), ['InventoryProductApp']);
});
})();

script load order
<script src="~/theme/modern/assets/global/plugins/angularjs/angular.min.js"></script>
<script src="~/App/Inventory/Product/ProductApp.js"></script>
<script src="~/App/Inventory/Product/LocationsFactory.js"></script>
<script src="~/App/Inventory/Product/LocationsController.js"></script>
In your controller:
angular.module('InventoryProductApp').controller("LocationsController",
['$scope', '$log', 'LocationsFactory', function ($scope, $http, $log, LocationsFactory) {
You're missing '$http' in your dependency injections, which means the LocationsFactory argument isn't filled at all.

I want to share data stored in variable from one controller to another

I have data in one controller and now I want to share it with another but both controller has different modules. I have used $rootscope but it didn't work. I have used service it also didn't work. link here Service
Is there any other way to do. I have spent one week for this please help me.
toolbar.controler
(function ()
{
'use strict';
angular
.module('app.toolbar')
.controller('ToolbarController', ToolbarController);
function ToolbarController($rootScope, $mdSidenav, msNavFoldService, $translate, $mdToast, $location, $localStorage, $http, $scope)
{
var vm = this;
vm.name = $localStorage.name;
vm.userId = $localStorage._id;
vm.readNotifications = function(notifId){
$http({
url: 'http://192.168.2.8:7200/api/readNotification',
method: 'POST',
data: {notificationId: notifId, userId: vm.userId}
}).then(function(res){
vm.rslt = res.data.result1;
console.log(vm.rslt);
vm.refresh();
$location.path('/sharedwishlistdetails');
}, function(error){
alert(error.data);
})
}
}
})();
The data stored here in vm.reslt.
toolbar.module.js
(function ()
{
'use strict';
angular
.module('app.toolbar', [])
.config(config);
/** #ngInject */
function config($stateProvider, $translatePartialLoaderProvider)
{
$translatePartialLoaderProvider.addPart('app/toolbar');
}
})();
Now I want that result for this controller.
sharedwishlistdetails.controller.js
(function ()
{
'use strict';
angular
.module('app.sharedwishlistdetails')
.controller('SharedWishlistDetailsController', SharedWishlistDetailsController);
/** #ngInject */
//NotificationsController.$inject = ['$http', '$location'];
function SharedWishlistDetailsController($http, $location, $localStorage, $rootScope, $scope)
{
var vm = this;
vm.uid = $localStorage._id;
}
})();
shareddata.service.js
(function ()
{
'use strict';
angular
.module('app.core')
.factory('shareData', shareDataService);
/** #ngInject */
function shareDataService($resource,$http) {
var shareData = {};
return shareData;
}
})();
write a service in 'app.toolbar' module
angular.module('app.toolbar').service('ServiceA', function() {
this.getValue = function() {
return this.myValue;
};
this.setValue = function(newValue) {
this.myValue = newValue;
}
});
In your toolbarController , inject ServiceA and set data -
vm.readNotifications = function(notifId){
$http({
url: 'http://192.168.2.8:7200/api/readNotification',
method: 'POST',
data: {notificationId: notifId, userId: vm.userId}
}).then(function(res){
vm.rslt = res.data.result1;
ServiceA.setValue(vm.rslt);
console.log(vm.rslt);
vm.refresh();
$location.path('/sharedwishlistdetails');
}, function(error){
alert(error.data);
})
}
Now write another service for 'app.sharedwishlistdetails' module -
angular.module('app.sharedwishlistdetails',['app.toolbar']).service('ServiceB', function(ServiceA) {
this.getValue = function() {
return ServiceA.getValue();
};
this.setValue = function() {
ServiceA.setValue('New value');
}
});
Now inject ServiceB in your SharedWishlistDetailsController controller and access data -
var sharedData = ServiceB.getValue();
How could $rootScope failed in your code it would be appreciated if you paste your code: never mind here is an example that will help you out:
All applications have a $rootScope which is the scope created on the HTML element that contains the ng-app directive.
The rootScope is available in the entire application.If a variable has the same name in both the current scope and in the rootScope, the application use the one in the current scope.
angular.module('myApp', [])
.run(function($rootScope) {
$rootScope.test = new Date();
})
.controller('myCtrl', function($scope, $rootScope) {
$scope.change = function() {
$scope.test = new Date();
};
$scope.getOrig = function() {
return $rootScope.test;
};
})
.controller('myCtrl2', function($scope, $rootScope) {
$scope.change = function() {
$scope.test = new Date();
};
$scope.changeRs = function() {
$rootScope.test = new Date();
};
$scope.getOrig = function() {
return $rootScope.test;
};
});

How can I passing Parameter angularjs factory $http and $stateParameters

App.factory('menuService', function ($http) {
var urlBase = 'Services/MenuService.asmx/GetAllMenu';
var factory = {};
factory.getAllMenus= function () {
return $http.get(urlBase);
};
return factory;
});
Controller:
App.controller("sampleController", function ($scope, menuService) {
$scope.List = [];
var menuData=function(data, status){
$scope.List = data;
console.log($scope.List);
}
menuService.getAllMenus().success(menuData);
});
/// Working perfect...
How can i use same service by other controller?
I've tried this one but wrong...
App.controller("viewDetailMenu", function ($scope, menuService, $stateParams) {
$scope.menu = menuService.getMenu($stateParams.id);
});
Here I share image how it look..
Please help me!...
You need to have all functions/methods defined if you want to use them. You getMenu function/method is not defined so it will generate an error. Please look at below code. You can add number of functions. You factory is share by all controllers so you can use it in any controller.
App.factory('menuService', function ($http) {
var urlBase = 'Services/MenuService.asmx/GetAllMenu';
var factory = {};
factory.getAllMenus= function () {
return $http.get(urlBase);
},
factory.getMenu=function(id){
return $http.get(urlBase +"/ID="+ id) // write it according to your API.
}
return factory;
});
And then,
App.controller("viewDetailMenu", function ($scope, menuService, $stateParams) {
$scope.menu = menuService.getMenu($stateParams.id).success(function(data,status){
}).error(function(data,status){
});
});

losing scope data outside $http service

I'm new in angularjs and i have a problem trying to use $scope inside a $http.
inside $http i can see data but outside service i get null.
Console.log($scope.data) inside service I get data:
Console.log($scope.data) outside always null:
mycode :
(function (app, ng) {
'use strict';
app.controller('mainController', ['$scope', 'ServicePatient', function ($scope, ServicePatient) {
$scope.data = null;
ServicePatient.all().success(function (data) {
$scope.data = data;
});
$scope.sortType = 'last_Name'; // the default sort type
$scope.sortReverse = false; // the default sort order
$scope.search = ''; // the default search/filter term
$scope.filterEnabled = '';
$scope.setEnabled = function(status){
$scope.filterEnabled = status;
if(status){
angular.element(document.querySelector( '#enabledFalse')).removeClass('active-btn');
angular.element(document.querySelector( '#enabledTrue')).addClass('active-btn');
} else {
angular.element(document.querySelector( '#enabledTrue')).removeClass('active-btn');
angular.element(document.querySelector( '#enabledFalse')).addClass('active-btn');
}
}
console.log($scope.data);
}]);
app.service('ServicePatient', ['$http', function ($http) {
function all() {
return $http({
url: 'http://54.165.192.65/ekare/ws6.php?request=patient',
method: 'GET'
});
}
return {
all: all
}
}]);
}(angular.module('app', []), angular));

AngularJS - factory is an empty object

I'm new in AngularJS - I can't figure out why I get the error mainDataService.refreshStatus is not a function in the $scope.clickMe function. I see the mainDataService variable is an empty object besides its initialization. What am I doing wrong here ?
var mainDataService = {};
var firstModule = angular.module('myModule', ['ngRoute', 'ngAnimate']);
(function () {
var mainDataServiceInjectParams = ['$http', '$q'];
var mainFactory = function ($http, $q) {
mainDataService.refreshStatus = function (id) {
return $http.get('/api/values/' + id).then(function (results) {
return results.data;
});
};
return mainDataService;
};
mainFactory.$inject = mainDataServiceInjectParams;
firstModule = firstModule.factory('mainService', mainFactory);
}());
firstModule.controller('myCtrl', function ($scope, $http) {
$scope.TST = '1';
$scope.clickMe = function (id) {
mainDataService.refreshStatus(id).then(function (results) {
$scope.TST = results;
});
}
});
You need to use the dependency injection mechanism to load your own services.
Put the mainDataService declaration in a local scope and inject the mainService into myCtrl:
var firstModule = angular.module('myModule', ['ngRoute', 'ngAnimate']);
(function () {
var mainDataServiceInjectParams = ['$http', '$q'];
var mainFactory = function ($http, $q) {
var mainDataService = {};
mainDataService.refreshStatus = function (id) {
return $http.get('/api/values/' + id).then(function (results) {
return results.data;
});
};
return mainDataService;
};
mainFactory.$inject = mainDataServiceInjectParams;
firstModule = firstModule.factory('mainService', mainFactory);
}());
firstModule.controller('myCtrl', function ($scope, $http, mainService) {
$scope.TST = '1';
$scope.clickMe = function (id) {
mainService.refreshStatus(id).then(function (results) {
$scope.TST = results;
});
}
});
Even better, you should explicitly assign the dependencies into the controller, so that your code still works after minifcation (as you already did it for the service):
firstModule.controller('myCtrl', myCtrl);
myCtrl.$inject = ['$scope', '$http', 'mainService'];
function myCtrl($scope, $http, mainService) {
$scope.TST = '1';
$scope.clickMe = function (id) {
mainService.refreshStatus(id).then(function (results) {
$scope.TST = results;
});
}
});
As you see, if you use normal function definitions, you can make use the function hoisting of Javascript and write the functions at the end while having the relevant code at the top. It's the other way round as in your example of the service.
Supply mainService to controller
firstModule.controller('myCtrl', function ($scope, $http, mainService) {
and then use it in the function
mainService.refreshStatus
I think you immediately invoked function is not invoked so mainDataService still reference the object you set at the first line
(function(){})()
rather than
(function(){}())
