I'm new to angular and am having trouble set my project up. I have tried everything I have seen on google and stackoverflow(please do not send link to similar question).. None have worked. Im using angular 1.5.5 and refer to the cdn. here is what my code looks like. Thanks!
<html ng-app="boatup">
<link href="css/one-page-wonder.css" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular-route.js"></script>
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
</head>
<body ng-controller="mainCtrl">
</body>
//in app.js
var app = angular.module('boatup', [
'boatup.controllers',
'ngRoute'
]);
//in controllers.js
app.controller('mainCtrl', function($scope) {
console.log("hello");
});
The error is angular.js:38 Uncaught Error: [$injector:modulerr] in angular.js 38
Thanks for any help in advance.
Uncaught reference error in angular is caused when you are either using a module with no definition or the file with the module definition is not loaded in scripts. You have not declared the boatup.controllers module but added it as a dependency to your main module. Either declare and define boatup.controllers or remove it as a dependency as below:
angular.module('boatup', [
'ngRoute'
]);
Replace this with your code.
//in app.js
angular.module('boatup', [
'ngRoute'
]);
//in controllers.js
angular.module('boatup')
.controller('mainCtrl', function($scope) {
console.log("hello");
});
As far as I can see from your description, you've started your project with creating different files with your application's modules. That's a good descision. But!
You instantiated your main app's module and assigned it to global variable app. It's not that big deal, but better avoid creating unnecessary variable in global scope. And if you devine gloabl variable app in different files, it will be owerwritten with the last file loaded.
You must load your module with controllers before main module. Otherwise you'll get [$injector:modulerr].
So in your case the following solution will work.
controllers.js
angular.module('boatup.controllers', [])
.controller('mainCtrl', ['$scope', function($scope) {
console.log('hello');
}])
app.js
angular.module('boatup', ['ngRoute', 'boatup.controllers']);
And you need to load in appropriate order.

I'm just starting to learn Angular so the issue I'm trying to figure out here might be a bit awkwardly formulated. I'll try my best and explain what I'm dealig with.
I have a main main.js module file where I have declared
angular.module('app', [
'ngRoute'
])
Now I have a separrate file for the controller as home.controller.js which contains
angular
.module('app')
.controller('HomeController', ['$scope', function($scope) {
}]);
Is there any way to include the home.controller.js file withing the main.js file without having to put the script src in the html ? I have tried to import 'path/home.conntroller.js but I get this error
Module 'app' is not available! You either misspelled the module name or forgot to load it.
Appreciate the help.
Make sure main.js is included in your HTML file before home.controller.js ... for example:
<script src="main.js"></script>
<script src="home.controller.js"></script>
I just started with Angular and I'm little bit confused with this error.
I don't know exactly what I've done wrong, but my console is showing this error:
angular.js:38 Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.5.8/$injector/modulerr?p0=app&p1=Error%3A%20%…(http%3A%2F%2Flocalhost%3A8080%2Flib%2Fangular%2Fangular.min.js%3A21%3A179)(…)
my html:
<!DOCTYPE html>
<html lang="en" ng-app="app">
<head>
<link rel="stylesheet" href="css/app.min.css">
<script src="lib/angular/angular.min.js"></script>
<script src="lib/angular-route/angular-route.min.js"></script>
<script src="lib/angular-resource/angular-resource.min.js"></script>
<script src="js/app.js"></script>
<script src="js/controller.js"></script>
</head>
<body>
test
</body>
</html>
and my app.js:
(function() {
'use strict';
angular.module('app', [
'ngRoute',
'ngResource',
'mainController'
])
.config(['$routeProvider', function() {
routeProvider.when("/", {templateUrl: 'www/index.html', controller: 'mainController'})
}])
.controller('mainController', function($scope){
alert();
})
})();
what is wrong ?
The mainController is not a module but a controller inside your app module. So injecting mainController does not make sense here. Remove the mainController injection from your modules dependencies array.
The other dependencies, ngRoute and ngResources are modules which your module is depending upon - for eg, $routeProvider is from the ngRoute module, so in order to get routeProvider, you need to inject the ngRoute module as dependency.
You don't have to inject controller as a dependency to the module
Change,
angular.module('app', ['ngRoute','ngResource','mainController'])
To
angular.module('app', ['ngRoute','ngResource'])
DEMO
First and foremost, do not inject the controller as a dependency. Remember: you are registering it after you create the module, and adding it to that model. Thus, it would make no sense to inject it at the time of creating the module. It doesn't exist yet. Makes sense?
Then some stuff to make life easier for you: separate out your app config stuff from your controller registrations. Have an app.js for example doing the code below. Notice I separated the steps, and I also create a config function that I then call in the app.config. This is just a bit more readable in the JavaScript mess we have to deal with.
(function() {
'use strict';
var app = angular.module('app', ['ngResource']);
var config = function(routeProvider){
routeProvider.when("/", {templateUrl: 'www/index.html', controller: 'mainController'});
};
app.config(['$routerProvider'], config);
})
})();
Then have a mainController.js containing the controller code and the registration of it. It'll be more future-proof for when you start adding more controllers and services and so on. Also, don't use $scope, use 'this' instead, you can use that from version 1.5 I think. Only place when you need to use $scope because 'this' doesn't work there is in angular charts, just a heads up ;)
(function ()
{
'use strict';
var mainController = function ($scope,)
{
var vm = this;
vm.variable = "value";
};
angular.module('app').controller('mainController', ['', mainController]);
})();
Btw don't mind the strange indentation of the code snippets, the editor on this page is messing with me a bit ;)
I'm trying to setup angular in mu app with really basic code, but it keeps giving me the following error:
Uncaught ReferenceError: $scope is not defined
What I have is the following:
<!DOCTYPE html>
<html ng-app="test">
<head>
<!-- Other JS files here including jQuery!! -->
<script src="~/Scripts/angular.js" type="text/javascript"></script>
</head>
<script src="~/Scripts/angular.js" type="text/javascript"></script>
</html>
In app.js I have:
var blaat11 = angular.module('test', []);
blaat11.controller('TestController', [$scope, function ($scope) {
var aa = $scope.test;
}]);
But I'm getting the error I posted earlier. I want to inject services into my controller like that. I've done it before like this and never had any trouble with it.
Anyone any idea why it isn't working?
Wrap the $scope in quotes. This is used for mapping of the Dependency injections in case of minifying the code. As the $scope outside of the controller is not defined, the error is thrown.
blaat11.controller('TestController', ['$scope', function($scope) {
I'm getting error when adding ng-controller="HeaderController" to a div.
Error: ng:areq
Bad Argument
Argument 'HeaderController' is not a function, got undefined
my HTML looks like that:
<div ng-app="myApp">
<div ng-controller="HeaderController">
</div>
<div ng-controller="PostController">
</div>
</div>
Also I include following files:
MyApp.js
var myApp = angular.module('myApp', ['postServices', 'angularFileUpload', 'ngSanitize', 'ui.date', 'bootstrapLightbox', 'profileServices']);
HeaderController.js
myApp.controller('HeaderController', ['$scope', 'PostServices', '$http', function($scope, PostServices, $http) {
$scope.getBookmarksCount = function() {
PostServices.getBookmarksCount().then(function(response) {
if (response.data.status == 'success') {
$scope.bookmarksCount = response.data.bookmarksCount;
} else {
$scope.errorMessage = response.data.message;
}
})
};
}]);
PostController.js beggining of this file looks like:
myApp.controller('PostController', ['$scope', 'PostServices', '$http', 'FileUploader', 'Lightbox',function($scope, PostServices, $http, FileUploader, Lightbox) {
PostService.js contains a module named postServices and it contains a service PostServices:
angular.module('postServices', [])
.service('PostServices', ['$http', function($http) {
if I delete ng-controller="HeaderController" everything works fine.
Does anyone knows what could be the problem?
In your module you add the postServices without a capital at the start, while you add it in your headercontroller as PostServices. This might mess with the forming of your headercontroller.
Either one of those could be a typo, but it is very important that you inject the service precisely as it is defined (in your .service or .factory) in the ['PostService', bit. So if the service is called: postService, you should inject it in your controller as: ['postService, function(someNameThatDoesntMatter) if its called PostService, inject it as ['PostService', function(someNameThatDoesntMatter)
As I just shown, how you call it afterwards in the function parameter is up to you.
Update
You could create a module for your controllers to fix this. Make sure to inject your postServices in this module aswell. Then inject the controllers module in your myApp module :-) The benefit of working in a structured way like this, is that you can create a structure of including your JS which you can apply on every project you work on.
I don't know which version of Angular you use , I took 1.4.0 for my plunk example and try just to limit to the code you provide to see if I recreated the error.
I had to deal more with scripts inclusion order. It created error. The right order in order to make it work is
<link rel="stylesheet" href="style.css">
<script src="//code.angularjs.org/1.4.0/angular.js"></script>
<script src="MyApp.js"></script>
<script src="PostController.js"></script>
<script src="PostService.js"></script>
<script src="HeaderController.js"></script>
http://plnkr.co/edit/NhzQFmI1s9r98uAMZwYg
So Main point was to defined PostService.js before HeaderController
It seems likes
you forget include that HeaderController.js file in index.html.
Make sure your HeaderController.js is loaded properly.
Missing some where in gulp/grunt process.
I have been trying to learn some Angular.js using Angular.js Novice to Ninja.
The main problem that i have by now is that in the examples you have to files, app.js and controller.js.
The main module is declared in app.js and controllers.js as dependencies:
angular.module('myApp', [
'myApp.controllers',
'ngRoute'
]);
In controllers.js, controllers are declared like this:
angular.module('myApp.controllers').controller('BookController', function($scope){
$scope.name="Scope for BookController";
});
but it never works like that, i have to do this and keep everthing in the same file.
var app=angular.module('myApp', [
'myApp.controllers',
'ngRoute'
]);
app.controller('BookController', function($scope){
$scope.name="Scope for BookController";
});
Can someone tell me what is wrong? Thank you.
What does your debugger say?
My guess is you're loading the files in the wrong order. You see, you have to first define myApp.controllers to be able to load it in myApp, so make sure your controllers.js is injected first, and then app.js.
Please make sure that you load the files in following order in head tag,
<script src="/path_to/angular/angular.js"></script>
<script src="/path_to/app.js"></script>
<script src="/path_to_controllers/controllers.js"></script>
Also please add following line to the app.js,
myApp.controllers = angular.module('myApp.controllers',[])
And change your code to following in controller.js,
myApp.controllers.controller('BookController', function($scope){
$scope.name="Scope for BookController";
});
Hope this will resolve your issue.
