I'm facing problem while initializing a third party JavaScript API (iHUB) inside RUN method of AngularJS. Currently the code is behaving in asynchronous mode. I want IHUB to first initialize and then AngularJS route/controller should get called. (Is it possible to make utilization of the callback method provided by IHUB ?)
var nameApp = angular.module('nameApp', ['ngRoute']);
nameApp.run(['$window', 'myService', function($window, myService) {
//initialize IHUB
var actuate= new actuate();
actuate.initialize('http://localhost:8700/iportal', settings.reqOps, "user", "pwd", callback);
function callback(){
alert('started!!');
}
}]);
nameApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/:tabname', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'tabDetailCtrl'
}).
when('/:tabname/:reportName', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'reportDetailCtrl'
}).
otherwise({
redirectTo: '/Buy Side Dashboard'
});
}]);
There is only one way to achieve a "real" before AngularJS initialization behavior by using angular.bootstrap();. This allows you to initialize your AngularJS application manually.
Note: You should not use the ng-app directive when manually bootstrapping your app.
> Fiddle demo
View
<div ng-controller="MyController">
Hello, {{greetMe}}!
</div>
Application
angular.module('myApp', [])
.controller('MyController', ['$scope', function ($scope) {
$scope.greetMe = 'World';
}]);
var actuateDummy = {
initialize: function (callback) {
setTimeout(callback, 2500);
}
};
actuateDummy.initialize(function () {
angular.element(function() {
angular.bootstrap(document, ['myApp']);
});
})
This is an other approach which uses the resolve state of ui-router. This service only initializes iHUB if it not has been initialized yet:
This service also returns the actuate object. In that way you can use it in your controller or components after init.

View
<nav>
<a ui-sref="state1">State 1</a>
<a ui-sref="state2">State 2</a>
</nav>
<div ui-view></div>
AngularJS Application
var myApp = angular.module("myApp", ["ui.router"]);
myApp.config(function($stateProvider, $urlRouterProvider) {
$stateProvider.state("state1", {
url: "#",
template: "<p>State 1</p>",
controller: "Ctrl1",
resolve: {
iHubInit: function(iHubService) {
return iHubService.init()
}
}
}).state("state2", {
url: "#",
template: "<p>State 2</p>",
controller: "Ctrl2",
resolve: {
iHubInit: function(iHubService) {
return iHubService.init()
}
}
});
});
myApp.controller("Ctrl1", function($scope, iHubService) {
console.log("Ctrl1 loaded.");
});
myApp.controller("Ctrl2", function($scope, iHubService) {
console.log("Ctrl2 loaded.");
});
myApp.service('iHubService', ["$q", function($q) {
this.iHubServiceInitialized = false;
this.actuate = null;
this.init = function() {
if (!this.iHubServiceInitialized) {
//Init
var self = this;
var deferred = $q.defer();
this.actuate = new actuate();
//initialize
this.actuate.initialize('http://localhost:8700/iportal', settings.reqOps, "user", "pwd", function() {
self.iHubServiceInitialized = true;
deferred.resolve(self.actuate);
});
return deferred.promise;
} else {
return this.actuate;
}
}
}]);
Try to add a resolve attribute when configuring your route provider like below:
var nameApp = angular.module('nameApp', ['ngRoute']);
nameApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/:tabname', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'tabDetailCtrl',
resolve: {
ihubInit: ['iHubService', function (iHubService) {
return iHubService.init();
}]
}
}).
when('/:tabname/:reportName', {
templateUrl: 'pages/analyticsDetail.html',
controller: 'reportDetailCtrl',
resolve: {
ihubInit: ['iHubService', function (iHubService) {
return iHubService.init();
}]
}
}).
otherwise({
redirectTo: '/Buy Side Dashboard'
});
}]);
nameApp.service('iHubService', ["$q", function($q){
this.init = function() {
var deferred = $q.defer();
var actuate= new actuate();
actuate.initialize('http://localhost:8700/iportal', settings.reqOps, "user", "pwd", callback);
function callback(){
deferred.resolve();
}
return deferred.promise;
}
}]);
Hi This is my first angularjs app and i am facing problem in injecting controller. I have one page called index.html and described as below.
<body ng-app="RoslpApp">
<div ng-controller="RoslpAppController">
<div class="popup">
<label>Language</label>
<select ng-model="selectedItem">
<option>العربية</option>
<option>English</option>
</select>
<button ng-click="clickHandler(selectedItem)">Submit</button>
</div>
</div>
</body>
This is my js file.
var app = angular.module('RoslpApp', ['pascalprecht.translate', 'ui.router']);
app.config(function ($stateProvider, $urlRouterProvider, $urlRouterProvider, $translateProvider, $translatePartialLoaderProvider) {
$stateProvider
// HOME STATES AND NESTED VIEWS ========================================
.state('Registration', {
url: '/Registration',
templateUrl: 'Registration/Registration.html'
});
$translatePartialLoaderProvider.addPart('Main');
$translateProvider.useLoader('$translatePartialLoader', {
urlTemplate: "Scripts/Locales/{part}/{lang}.json"
});
$translateProvider.preferredLanguage('en_US');
app.run(function ($rootScope, $translate) {
$rootScope.$on('$translatePartialLoaderStructureChanged', function () {
$translate.refresh();
});
});
app.controller('RoslpAppController', ['$scope', '$translate', function ($scope, $translate) {
$scope.clickHandler = function (key) {
$translate.use(key);
};
}]);
});
Whenever i select langualge from the dropdown and click on submit i get Argument RoslpAppController is not a function, got undefined error. May i get some help to fix this error?
Any help would be appreciated. Thank you.
Move the controller outside the app.config.
app.controller('RoslpAppController', ['$scope', '$translate', function ($scope, $translate) {
$scope.clickHandler = function (key) {
$translate.use(key);
};
}]);
I created custom service
(function () {
"use strict";
angular
.module("common.services")
.factory("redirectService",
["$q", "$location",
redirectService])
.config(function ($httpProvider) {
$httpProvider.interceptors.push('redirectService');
});
function redirectService($q, $location){
...
var redirect = function() {
...
};
return {
doRedirect: redirect
};
}
inside my other controller where I'm injecting this redirectService I'm trying to call this publish doRedirect method
angular
.module("myModule")
.controller("MyController",
["$scope",
"redirectService"
MyController]);
function MyController(redirectService){
vm.doClick = function() {
redirectService.doRedirect();
}
}
Here I'm getting error on calling doRedirect method
Error: redirectService.doRedirect is not a function
You have an imbalance of number of arguments in dependency array and function arguments for MyController
Change
function MyController(redirectService){
To
function MyController($scope, redirectService){
MyController function has two arguments first $scope, second redirectService
angular
.module("myModule")
.controller("MyController",
["$scope",
"redirectService"
MyController]);
function MyController($scope, redirectService){
vm.doClick = function() {
redirectService.doRedirect();
}
}
I have simple example using Angular UI Bootstrap modal service. In this example I don't understand why model binding is not working. Instead of seeing "Doing something..." on modal dialog I see "{{message}}". What I need to change?
Example is here:
http://plnkr.co/edit/fJhS3e7At11tJTuNSWAB?p=preview
modal html looks like this:
<div ng-app="myModule">
<div ng-controller="modalInstanceController" class="modal-body">
<div>{{message}}</div>
</div>
</div>
And definition of module and controllers:
var myAppModule = angular.module('myModule', ['ui.bootstrap']);
myAppModule.controller('modalInstanceController', function ($scope, $modalInstance, message) {
var vm = this;
vm.message = message;
});
myAppModule.controller('myController', function ($scope, $modal) {
$scope.open = function open() {
var modalInstance = $modal.open({
templateUrl: 'modal.html',
backdrop: 'static',
//windowClass: 'custom-modal-wait',
dialogFade: false,
keyboard: false,
controller: 'modalInstanceController',
resolve: {
message: function () {
return "Doing something ...";
}
}
});
setTimeout(function(){
modalInstance.close('close');
},5000);
}
});
to use the value you pass to the modal, you need to put it on its scope, so set the modal controller as so:
myAppModule.controller('modalInstanceController', function ($scope, $modalInstance, message) {
$scope.message = message;
});
and remove the ng-controller from modal.html, you are already assigning him a controller when you create the modal instance
ng-controller="modalInstanceController"
your fixed example : http://plnkr.co/edit/vnfL72EBMXsQ1NzlJNEF?p=preview
In this simplified scenario, I have two files: index.htm, lazy.htm.
index.htm:
var myApp = angular.module('myApp', []);
myApp.controller('embed',function($scope){
$scope.embed = 'Embedded Controller';
});
<div ng-controller="embed">{{embed}}</div>
<div ng-include="'lazy.htm'"></div>
lazy.htm
myApp.controller('lazy',function($scope){
$scope.lazy = 'Lazy Controller';
});
<div ng-controller="lazy">
{{lazy}}
</div>
The result is an error: "Argument 'lazy' is not a function, got undefined"
Using a function instead
lazy.htm
function lazy($scope) {
$scope.lazy = 'Lazy Controller';
}
<div ng-controller="lazy">
{{lazy}}
</div>
This works until version 1.3 beta 14. In beta 15 was removed the global controller functions: https://github.com/angular/angular.js/issues/8296
So now, what is the better way to get angularized contents of lazy.htm dynamically?
UPDATE:
In this article (http://ify.io/lazy-loading-in-angularjs) I found another possible solution. The $controllerProvider allow us to register new controllers after angular bootstrap. Works like a charm. Tested in v1.3.0-beta.18
index.htm:
var myApp = angular.module('myApp', [])
.controller('embed',function($scope){
$scope.embed = 'Embedded Controller';
})
.config(function($controllerProvider) {
myApp.cp = $controllerProvider;
});
<div ng-controller="embed">{{embed}}</div>
<div ng-include="'lazy.htm'"></div>
lazy.htm
myApp.cp.register('lazy',function($scope){
$scope.lazy = 'Lazy Controller';
});
<div ng-controller="lazy">
{{lazy}}
</div>
UPDATE 2:
Two other alternatives that works are:
lazy.htm
_app = $('[ng-app]').scope();
_app.lazy = function($scope) {
$scope.lazy = 'Lazy Controller';
};
OR
var $rootScope = $('[ng-app]').injector().get('$rootScope');
$rootScope.lazy = function($scope) {
$scope.lazy = 'Lazy Controller';
};
But I believe these last two examples should not be used in production.
You can also use the jquery with the resolve the $routeProvider
app.js
/* Module Creation */
var app = angular.module ('app', ['ngRoute']);
app.config(['$routeProvider', '$controllerProvider', function($routeProvider, $controllerProvider){
/*Creating a more synthesized form of service of $ controllerProvider.register*/
app.registerCtrl = $controllerProvider.register;
function loadScript(path) {
var result = $.Deferred(),
script = document.createElement("script");
script.async = "async";
script.type = "text/javascript";
script.src = path;
script.onload = script.onreadystatechange = function (_, isAbort) {
if (!script.readyState || /loaded|complete/.test(script.readyState)) {
if (isAbort)
result.reject();
else
result.resolve();
}
};
script.onerror = function () { result.reject(); };
document.querySelector("head").appendChild(script);
return result.promise();
}
function loader(arrayName){
return {
load: function($q){
var deferred = $q.defer(),
map = arrayName.map(function(name) {
return loadScript('js/controllers/'+name+".js");
});
$q.all(map).then(function(r){
deferred.resolve();
});
return deferred.promise;
}
};
}
$routeProvider
.when('/', {
templateUrl: 'views/foo.html',
resolve: loader(['foo'])
})
.when('/bar',{
templateUrl: 'views/bar.html',
controller: 'BarCtrl',
resolve: loader(['bar'])
})
.otherwise({
redirectTo: document.location.pathname
});
}]);
/views/foo.html
<section ng-controller='FooCtrl'>
{{text}}
</section>
js/controllers/foo.js
/*Here we use the synthesized version of $controllerProvider.register
to register the controller in view*/
app.registerCtrl('FooCtrl',function($scope){
$scope.text = 'Test';
});
/views/bar.html
<section>
{{text2}}
</section>
js/controllers/bar.js
app.registerCtrl('BarCtrl',function($scope){
$scope.text2 = 'Test';
});
////JConfig file--------
window.angularApp.config(function ($routeProvider,$controllerProvider,$compileProvider,$provide, azMessages) {
$routeProvider.when('/login', {
resolve: {
load: ['$q', '$rootScope', function ($q, $rootScope) {
var deferred = $q.defer();
require([
//load required Js file here
], function () {
$rootScope.$apply(function () {
deferred.resolve();
});
});
return deferred.promise;
} ]
}
});
$routeProvider.otherwise({ redirectTo: '/login' });
window.angularApp.components = {
controller: $controllerProvider.register,
service: $provide.service,
directive: $compileProvider.directive
}
//contoller declaration
angularApp.components.controller('DiscussionController',[function(){
}]);
At first I utilized André Betiolo's answer. However, it does not always work becasue the ajax loading is non-blocking causing the view to sometimes request the controller prior to the script being loaded.
As a solution i forced the function not to return until all scripts successfully loaded. This is kind of hackish but makes sure the loads are successful prior to completing the resolve. It also allows for loading of multiple controllers.
app.js
var app = angular.module ('app', ['ngRoute']);
app.config(['$routeProvider', '$controllerProvider', function($routeProvider, $controllerProvider){
/*Creating a more synthesized form of service of $ controllerProvider.register*/
app.registerCtrl = $controllerProvider.register;
//jquery to dynamically include controllers as needed
function controllers(controllers){
var numLoaded = 0;
for (i = 0; i < controllers.length; i++) {
$.ajaxSetup({async:false});
$.getScript('js/controllers/' + controllers[i] + '.js').success(function(){
numLoaded++;
if (numLoaded == controllers.length) {
return true; //only return after all scripts are loaded, this is blocking, and will fail if all scripts aren't loaded.
}
});
}
}
$routeProvider
.when('/', {
templateUrl: 'views/foo.html',
resolve: {
load: function () {
controllers(['foo'])
}
}
})
.when('/bar',{
templateUrl: 'views/bar.html',
controller: 'BarCtrl',
resolve: {
load: function () {
controllers(['bar','foo']) //you can load multiple controller files
}
}
})
.otherwise({
redirectTo: document.location.pathname
});
}]);
/views/foo.html
<section ng-controller='FooCtrl'>
{{text}}
</section>
/views/bar.html
<section ng-controller='BarCtrl'>
{{text2}}
</section>
<section ng-controller='FooCtrl'>
{{text}}
</section>
/controllers/bar.js
app.registerCtrl('BarCtrl',function($scope){
$scope.text2 = 'Test';
});
You can have pure AngularJS lazy loading.
Create "LazyService":
var ng = angular.module('app');
ng.factory('lazyService', [ '$http', function($http) {
var jsPath = 'js/${ name }.js';
var promisesCache = {};
return {
loadScript: function(name) {
var path = jsPath.replace('${ name }', name);
var promise = promisesCache[name];
if (!promise) {
promise = $http.get(path);
promisesCache[name] = promise;
return promise.then(function(result) {
eval(result.data);
console.info('Loaded: ' + path);
});
}
return promise;
}
}
}]);
Then, define your config:
var ng = angular.module('app', [ 'ngRoute' ]);
ng.config([ '$routeProvider', '$controllerProvider', '$provide', function($routeProvider, $controllerProvider, $provide) {
// Lazy loading
ng.lazy = {
controller: $controllerProvider.register,
//directive: $compileProvider.directive,
//filter: $filterProvider.register,
factory: $provide.factory,
service: $provide.service
}
$routeProvider
.when('/', {
templateUrl: 'view/home.html'
})
.when('/vendor', {
templateUrl: 'view/vendor.html',
resolve: {
svc: [ 'lazyService', function(lazyService) {
return lazyService.loadScript('services/vendor');
}],
ctrl: [ 'lazyService', function(lazyService) {
return lazyService.loadScript('controllers/vendor');
}]
}
});
. . .
On "js/services/vendor.js", create service as:
var ng = angular.module('app');
ng.lazy.service('vendorService', [ function() {
. . .
On "js/controllers/vendor.js", create controller as:
var ng = angular.module('app');
ng.lazy.controller('vendorController', [ function() {
. . .
The "resolve" property on when defines which promises should be resolved before route loads.
The best way to do what you are asking is to instead use a directive and tie the controller and template together that way so its bound at the appropriate time. Currently, the binding it not happening in lazy.htm at the right time unless you declare a global function as you've shown in your second example.
Ideally - Angular will force you to separate HTML and JS as in newer versions this may be enforced more often.
You may have to use requireJS
http://solutionoptimist.com/2013/09/30/requirejs-angularjs-dependency-injection/
For the sake of trick can you try
ng-controller-controller="'lazy'"
or
In HTML
ng-controller-controller="myObject.controller"
Somewhere inject
$scope.myObject.controller = $controller('lazy', {$scope: $scope})
Try this ARI plugin for Angular JS. It helps you to lazy load the controller scripts on demand.
You also can use Directives to load your controller!
A example here:

I am sending you sample code. It is working fine for me. So please check this:
var myapp = angular.module('myapp', ['ngRoute']);

app.register = {
controller: $controllerProvider.register,
//directive: $compileProvider.directive,
//filter: $filterProvider.register,
//factory: $provide.factory,
//service: $provide.service
};
// so I keep a reference from when I ran my module config
function registerController(moduleName, controllerName) {
// Here I cannot get the controller function directly so I
// need to loop through the module's _invokeQueue to get it
var queue = angular.module(moduleName)._invokeQueue;
for (var i = 0; i < queue.length; i++) {
var call = queue[i];
if (call[0] == "$controllerProvider" &&
call[1] == "register" &&
call[2][0] == controllerName) {
app.register.controller(controllerName, call[2][1]);
}
}
