I am trying to load controllers dynamically using ocLazyLoad :
$ocLazyLoad.load('./ctrls/login.js');
But am getting this error saying:
The controller with the name 'loginCtrl' is not registered.
angular.module('optimusApp')
.controller('loginCtrl', function ($scope, $rootScope, $location, $http) {});
app.js
angular.module("optimusApp", ['ngRoute', 'oc.lazyLoad']);
angular.module('optimusApp')
.controller('globalCtrl', function ($rootScope, $location, $http, $routeParams, $ocLazyLoad) {
$ocLazyLoad.load('./ctrls/login.js');
});
I made it work by using ng-if
app.js
var optimusApp = angular.module("optimusApp", ["ngRoute", "oc.lazyLoad"])
.controller("globalCtrl", function ($rootScope, $location, $http, $routeParams, $ocLazyLoad) {
$ocLazyLoad.load("./js/app/login.js").then(function() {
console.log("loginCtrl loaded");
$rootScope.loginActive = true;
}, function(e) {
console.log("error");
});
});
login.js
optimusApp.controller('loginCtrl', function ($scope, $rootScope, $location, $http) {
});
HTML
<div ng-if="loginActive" ng-controller="loginCtrl">
</div>
Basically you will get the "registration error" if your ng-controller is in the page before you have the JS loaded.
So the ng-if is a solution, or I see you have ngRoute. So you could set ocLazyLoad to load the controller when entering a specific state.

I have the following code in my service:
testApp.service('detailsService',['databaseService', 'loggedService', '$http', function(databaseService, loggedService, $http){
var details;
this.getDetails = function(name){
return $http({
method : "GET",
url : name
}).then(function(response) {
details= response.data;
console.log(response.data);
return response.data;
});
};
}]);
What i want to do is call this function in my controller when the page(view) is loaded.
testApp.controller('testController', ['$scope', '$location', 'databaseService','detailsService', '$routeParams', function($scope, $location, databaseService, $routeParams, detailsService){
$scope.details;
var selectedDetails = function(name){
detailsService.getDetails(name).then(function(data){
$scope.details= data;
});
};
selectedDetails(name);
}]);
I keep getting the error detailsService.getDetails is not a function.
I'm using the same function from the detailsService in another controller without any problems.
Does anybody know why i keep getting this error?
The error is expected as you are not injecting dependencies properly, You need to use the correct sequence.
testApp.controller('testController', ['$scope',
'$location',
'databaseService',
'detailsService',
'$routeParams',
function($scope, $location, databaseService, detailsService, $routeParams ){
instead of
testApp.controller('testController', ['$scope',
'$location',
'databaseService',
'detailsService',
'$routeParams',
function($scope, $location, databaseService, $routeParams, detailsService){
Note Both the string part and the function arguments need to match up 1:1.
remove the promise in the service.Just return the request. since you are catching the promise from the controller no need to use it in the service
testApp.service('detailsService', ['databaseService', 'loggedService', '$http', function(databaseService, loggedService, $http) {
var details;
this.getDetails = function(name) {
return $http({
method: "GET",
url: name
})
};
}]);
Also make sure the sequence is correct order when you are injecting services.
change this
testApp.controller('testController', ['$scope', '$location', 'databaseService', 'detailsService', '$routeParams', function($scope, $location, databaseService, $routeParams, detailsService )
to this
testApp.controller('testController', ['$scope', '$location', 'databaseService', 'detailsService', '$routeParams', function($scope, $location, databaseService, detailsService , $routeParams)
controller
testApp.controller('testController', ['$scope', '$location', 'databaseService', 'detailsService', '$routeParams', function($scope, $location, databaseService, detailsService , $routeParams) {
$scope.details;
var selectedDetails = function(name) {
detailsService.getDetails(name).then(function(data) {
$scope.details = data;
});
};
selectedDetails(name);
}]);
I got this error because I had added a callback method to a component, but the callback was not used by all the pages where that component was used:
<component [myCallbackFn]="fnNameToBindToFn">
component.ts:
public onClick() {
// some code
this.myCallbackFn();
}
Each time it was not used I got this error which was effectively a NullPointerException (from Java). So in the other uses of <component> in my website I had to add a check in the component before the callback to say:
if (undefined !== this.myCallbackFn) this.myCallbackFn();
I got some problem when I'm trying to use an Angular service in the controlleur of my application.
When I'm trying to use function of my service in my controlleur, my console throw me an error :/
var app = angular.module('app', ['ngRoute'])
app.config(['$routeProvider',
function ($routeProvider) {
$routeProvider
.when('/login', {
controlleur: 'login',
templateUrl: 'modules/login/login.html'
})
.otherwise({
redirectTo: '/login'
});
}]);
app.service('coreServices', [function () {
this.helloConsole = function () {
console.log("console services");
};
}]);
app.controller('loginController', ['$scope', '$http', '$rootScope', '$location', 'coreServices', LoginController]);
function LoginController($scope, $http, $rootScope, coreServices) {
var vm = this;
vm.helloConsole = coreServices.helloConsole;
vm.helloConsole();
}
angular.js:13708 TypeError: vm.helloConsole is not a function
at new LoginController
I link you this fiddle to show you how I do: https://jsfiddle.net/h8yaxLap/2/
The error throwed is:
angular.js:13708 TypeError: vm.helloConsole is not a function
at new LoginController
Well in your example angular will map $location to coreService in the injected parameters in the function. So I would go for
app.controller('loginController', ['$scope', '$http', '$rootScope', '$location', 'coreServices', LoginController]);
function LoginController($scope, $http, $rootScope, $location, coreServices)
Change service function to return object
app.service('coreServices', function () {
return {
helloConsole: function () {
console.log("console services");
}
};
});
You missed $location parameter for the controller
function LoginController($scope, $http, $rootScope,$location, coreServices)
I'm new to Angular and cannot pinpoint where I am going wrong. I'm just trying to simply inject my factory into my controller, reference said: "Cannot read property 'validar' of undefined". I have two files, ServiceUtil.js where have a service and CentroCustoCtrl.js where I'm trying to use service's function.
The function at ServiceUtil.js:
(function () {
'use strict';
angular.module('Services', [])
.service('ValidarFormulario', [function () {
this.validar = function (form) {
var valido = true;
//code
}
return valido;
}
}]);
})();
And CentroCustoCtrl.js
(function () {
'use strict';
var app = angular.module("start", ['AxelSoft', 'ngLocalize',
'ngLocalize.Config', 'mvComponentes','Services'])
.value('localeConf', {
basePath: '../Scripts/Locales', ...
...
});
app.controller('CentroCustoCtrl', ['$scope', '$http', 'ValidarFormulario', function ($scope, $http, $rootScope, $timeout, ValidarFormulario) {
$scope.Salvar = function () {
if (ValidarFormulario.validar(document.getElementsByTagName('input'))) { ...// Cannot read property 'validar' of undefined
);
I tried with factory , but not worked too:
angular.module('Services', [])
.factory('ValidarFormulario', [function () {
return{
validar : function (form) {
var valido = true;
//code
}
}
return valido;
}
}
}]);
})();
Please, I appreciate any help you can provide.
The problem is you had wrong dependency sequence inside DI inline array, basically they are mismatching in number and their sequences
app.controller('CentroCustoCtrl', ['$scope', '$http', 'ValidarFormulario',
//removed $rootScope, $timeout which wasn't used.
function ($scope, $http, ValidarFormulario) {
OR either way you could just add the dependency inside array, if they are really gonna used inside controller like below
app.controller('CentroCustoCtrl', ['$scope','$http','$rootScope','$timeout','ValidarFormulario',
function ($scope, $http, $rootScope, $timeout, ValidarFormulario) {
Just change the below line of code
app.controller('CentroCustoCtrl', ['$scope', '$http', 'ValidarFormulario', function ($scope, $http, $rootScope, $timeout, ValidarFormulario) {
to
app.controller('CentroCustoCtrl', ['$scope', '$http', '$rootScope', '$timeout', 'ValidarFormulario', function ($scope, $http, $rootScope, $timeout, ValidarFormulario) {
This should work.
Well, also I've saw that your controller injections are wrong. You have:
App.controller('CentroCustoCtrl', ['$scope', '$http', 'ValidarFormulario', function ($scope, $http, $rootScope, $timeout, ValidarFormulario)
And you should have:
app.controller('CentroCustoCtrl', ['$scope', '$http', '$rootScope', '$timeout', 'ValidarFormulario', function ($scope, $http, $rootScope,$timeout, ValidarFormulario)
Injectors on "[ ]" must mach with function parameters.
When you set a module the syntax is:
angular.module('Services', [ here injections ])
But when you get a module to use it, syntax must be:
angular.module('Services')
I have a service and a controller declared like this:
angular
.module('purchaseApp')
.service('sharedProperties', function() {
var stringValue = 'test string value';
return {
getString: function() {
return stringValue;
}
}
})
.controller('purchaseOrderCtrl', ['$scope', '$rootScope', '$location', '$http', function ($scope, $rootScope, $location, $http, sharedProperties) {
console.log(sharedProperties.getString());
});
When I try to access to the service in my controller, it returns me "undefined", but I don't know why... Could you help me?
Thanks.
Your controller is missing sharedProperties. You need to inject it. Add it after $http.
.controller('purchaseOrderCtrl', ['$scope', '$rootScope', '$location', '$http', 'sharedProperties', function ($scope, $rootScope, $location, $http, sharedProperties) {
console.log(sharedProperties.getString());
});
.controller('purchaseOrderCtrl', ['$scope', '$rootScope', '$location', '$http', **'sharedProperties'**, function ($scope, $rootScope, $location, $http, sharedProperties) {
console.log(sharedProperties.getString());
});
Add sharedProperties service in your controller dependent parameter as well.
I want to show a progress dialog as a model by using ui.bootstrap, so I included it as a dependency in my application as follows:
var app = angular.module('app', ['ngRoute','ngCookies','home','ui.bootstrap']);
After injecting it my controller is as follows:
angular.module('home', [])
.controller('homeCtrl', ['$scope', '$http', '$filter', '$route', '$routeParams', '$location', '$rootScope', 'showAlertSrvc', '$modal',
function ($scope, $http, $filter, $route, $routeParams, $location, $rootScope, showAlertSrvc, $modal) {
$scope.open = function () {
var modalInstance = $modal.open({
templateUrl: 'App/Register',
controller: 'registerCtrl',
//size: size,
resolve: {
items: function () {
return $scope.items;
}
}
});
//modalInstance.result.then(function (selectedItem) {
// $scope.selected = selectedItem;
//}, function () {
// //$log.info('Modal dismissed at: ' + new Date());
//});
};
}]);
And my HTML is :
<input type="submit" value="Show Model" class=" novalidate form-control" ng-click="open()" style="background-color:skyblue; height: 45px" />
My View is named as Register.cshtml residing in App directory. Also routing is active at this URL. But when I click the button nothing happens, I wonder if templateUrl expects URL in any other format here. Please suggest what am I missing here.
Try to specify the path to the template with extersions
templateUrl: 'App/Register.cshtml',
Other options for .open look fine.
