Facing the following error:-
Failed to instantiate module myApp due to:
Error: [$injector:nomod]
at Error (native)
at
If i remove the content from function then I am not facing the issue but when I put it in the function legislator and try to call it I get the issue. Is there any way to solve it by keeping it in the function only. I kind of need to use it again and again.
The code can be found at:-
https://raw.githubusercontent.com/anirbanmishra/congress.php/master/web_test
You have instantiated the module inside a function and called the function inside onclick.
<html lang="en" ng-app="myApp">
<a href="#legislator" onclick="legislator()">
<script>
function legislator() {
var app = angular.module('myApp', ['angularUtils.directives.dirPagination']);
....
}
</script>
That module instantiation part should be outside.
EDIT : For your second problem, angularUtils.directives.dirPagination should not be passed as a dependency in module instantiation.
This link might help you.
var app = angular.module('myApp', ['angularUtils.directives.dirPagination']);
should be replaced with
var app = angular.module('myApp', []);
Replacing this would still give you error about legislators.length not defined... That you need to look yourself, that's not related to angular, some issue with the http request you had made to getData.php.
I've been trying to set up basic AngularJS functionality for a project but have been hitting a brick wall when it comes to including angular-route. Both are version 1.4.8. I'm currently using gulp-require to concatenate my JS, here's my main javascript file
// =require ../components/jquery/dist/jquery.min.js
// =require ../components/angular/angular.js
// =require ../components/angular-route/angular-route.js
$(document).ready(function() {
// =require app/app.js
}); // Doc ready is done!
And my app.js file
var app = angular.module('myApp', ['ngRoute']);
app.controller("ctrl", ["$scope", 'ngRoute', function($scope) {
$scope.test = "It works!";
}]);
I've checked and all the files are concatenating properly. The ng-app and ng-controller attributes are on my HTML file. I've tried adding and removing the ngRoute injection and switching the order of the files but to no avail. It's frustrating since I used Angular 1.4.5 in almost the exact same way without these issues popping up but I can't replicate the same here even when going back. But the {{test}} variable in my HTML is still not rendering, and basic operations like {{2 + 3}} aren't either.
EDIT: here is the link to the original error message I'm currently receiving: http://tinyurl.com/zx3k85f
EDIT 2: The parts of my HTML code that's calling the app and the controller:
<html lang="en" ng-app="myApp">
<body ng-controller="ctrl">
</body>
</html>
I'm using nunjucks for HTML dynamic generation, although I've changed the syntax for this so it doesn't conflict with Angular's double curly braces.
You can't inject module as dependency inside controller, you should remove 'ngRoute' from the controller DI inline array.
app.controller("ctrl", ["$scope", , function($scope) {
Update
Basically the real problem is you are loading your angular component script using requirejs(lazily), so while you are having ng-app="myApp" with module name start looking for myApp module, and the module has not loaded therefore it throws an error .
So I'd recommend you to don't use ng-app directive to start angular on page load. Instead you should wait until all the scripts related to angular loaded, & then to bootstrap angular app lazily using angular.bootstrap method.
Code
$(document).ready(function() {
requirejs(["app/app.js"], function(util) {
angular.bootstrap(document, ['myApp']);
});
});
ngRoute is a provider that needs to be configured in the module config section before being used. Using it within a controller does not make any sense. Here the version that will work:
angular.module('myApp', ['ngRoute']);
angular.module('myApp').controller("ctrl", ["$scope",function($scope) {
$scope.test = "It works!";
}]);
Moreover, you need to call your module using directive ng-app=myapp in the html element where you plan to render your app.
I'm working on angular tutorial and i'm having a problem on beginning. Loading myApp module throws error. As explained in tutorial, this should be one of three ways to create controller.
Here is print screen from tutorial i'm working on:
When i refresh web page i get this error in Chrome console:
Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:nomod] Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
This is my HTML file
<html ng-app="myApp">
<head>
</head>
<body>
<h1>Hello world!</h1>
<div ng-controller="MainController">
{{ 2+2 }}
<br>
{{ val }}
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.7/angular.js"></script>
<script src="app.js">
</body>
</html>
This is my app.js file
var myApp = angular.module('myApp', []);
var MainController = function($scope){
$scope.val = "Main controller variable value"
}
So what is my problem? I can't figure it out.
Thank you in advance
Module 'myApp' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
Your original issue is due to the invalid script tag. Basically your script tag is not closed it needs to be closed in order for the browser to download the app.js file. Script tags are not self closing so it needs a closing tag.
<script src="app.js">
should be
<script src="app.js"></script>
Now once you fix that you will get into another error.
[ng:areq] Argument 'MainController' is not a function, got undefined
Since you are using the latest angular version, i.e anything >= 1.3.x needs the controller to be registered manually using the .controller construct. See here for more details.
Note - it is a bit confusing because the screenshot shows you using 1.2.0 (which does not necessarily needs explicit controller registration) but snippet in the question shown 1.4.x.
You should register a controller to the angular module myApp.
App.js
var myApp = angular.module('myApp', []);
myApp.controller('MainController', MainController );
var MainController = function($scope){
$scope.val = "Main controller variable value"
}
Basically what you were doing is correct but that code has been followed by the older version of AngularJS, The way you declared your controller is nothing but known as controller As function, which needs enable allowGlobals() method of $controllerProvider. Since Angular 1.3 + allowGlobals() method is disabled by adding below code, you could turn it on, to make your code working but it is not recommended way to do this.
Config
myApp.config(['$controllerProvider',
function($controllerProvider) {
$controllerProvider.allowGlobals();
}
]);
Refer same SO Answer here
Try this:
myApp.controller ("MainController",[$scope, function ($scope){
$scope.val = "Main controller variable value"
}]);
The ng-controller directive looks for the MainController in your MyApp module.
i cant figure out what is the problem
div#wrapper(ng-app="adminApp")
....
js/
var adminApp = angular.module('adminApp', ['ui-router']);
if i use
var adminApp = angular.module('adminApp', []);
the error disappear
why is that?
UPDATE:
adding image from console
the module name is ui-router but you need to inject ui.router and not ui-router
var adminApp = angular.module('adminApp', ['ui.router']);
check out PLUNKER LINK
It's a little late, but maybe it will save someone's time. In my case I've mixed up links: instead of angular-ui-router.min.js I've downloaded angular-route.min.js. Obviously angular-ui-router is necessary for this.
I also had a similar issue and in addition to following the steps outline above by "entre", I had to make sure the angularjs script tag comes before the ui-router tag as such:
<script src="Scripts/angular.min.js" type="text/javascript"></script>
<script src="scripts/angular-ui-router.min.js" type="text/javascript"></script>
The reverse order will also cause an $injector:modulerr
I noticed the same question was asked a few times here, I tried so solve it but nothing helps.
I'm following this tutorial with the egghead videos.
But when I get at the section of Controllers and Sharing data between controllers, I can't get it to work.
When I run it with Chrome, I get this error in the console:
'argument 'FirstCtrl' is not a function, got undefined'.
I really don't know what's wrong. The code is the same from in the tutorial.
HTML
<!DOCTYPE html>
<html ng-app>
<head>
<title>AngularJS Tutorials: Controllers</title>
<link rel="stylesheet" href="mystyle.css">
<script src="http://code.angularjs.org/1.2.0-rc.2/angular.min.js"></script>
</head>
<body>
<div ng-app="">
<div ng-controller="FirstCtrl">
<h1> {{data.message + " world"}}</h1>
<div class="{{data.message}}">
Wrap me in a foundation component
</div>
</div>
</div>
<script type="text/javascript" src="main.js"></script>
</body>
</html>
main.js
function FirstCtrl($scope){
$scope.data = { message: "Hello" };
}
You have 2 unnamed ng-app directives in your html.
Lose the one in your div.
Update
Let's try a different approach.
Define a module in your js file and assign the ng-appdirective to it. After that, define the controller like an ng component, not as a simple function:
<div ng-app="myAppName">
<!-- or what's the root node of your angular app -->
and the js part:
angular.module('myAppName', [])
.controller('FirstCtrl', function($scope) {
$scope.data = {message: 'Hello'};
});
Here's an online demo that is doing just that : http://jsfiddle.net/FssbL/1/
I got exactly the same error message and in my case it turned out i didn't list the controller JS file (e.g. first-ctrl.js) in my index.html
I just did this tutorial and followed #gion_13 answer. Still did not work. Solved it by making my ng-app name in the index identical to the one in my js file. Exactly identical, even the quotes. So:
<div ng-app="myapp">
<div ng-controller="FirstCtrl">
and the js:
angular.module("myapp", [])
.controller('FirstCtrl',function($scope) {
$scope.data= {message:"hello"};
});
Weird how the ng-app has to be identical but the ng-controller doesn't.
You must name your ng-app, giving your app a namespace; simply using ng-app is not enough.
Instead of:
<html ng-app>
...
You will need something like this instead:
<html ng-app="app">
...
Then, like so:
var app = angular.module("app", []).controller("ActionsController", function($scope){});
Another nice one: Accidentally redefining modules. I copy/pasted stuff a little too eagerly earlier today and ended up having a module definition somewhere, that I overrode with my controller definitions:
// controllers.js - dependencies in one place, perfectly fine
angular.module('my.controllers', [/* dependencies */]);
Then in my definitions, I was supposed to reference it like so:
// SomeCtrl.js - grab the module, add the controller
angular.module('my.controllers')
.controller('SomeCtrl', function() { /* ... */ });
What I did instead, was:
// Do not try this at home!
// SomeCtrl.js
angular.module('my.controllers', []) // <-- redefined module, no harm done yet
.controller('SomeCtrl', function() { /* ... */ });
// SomeOtherCtrl.js
angular.module('my.controllers', []) // <-- redefined module - SomeCtrl no longer accessible
.controller('SomeOtherCtrl', function() { /* ... */ });
Note the extra bracket in the call to angular.module.
remove ng-app="" from
<div ng-app="">
and simply make it
<div>
Me too faced the same issue. But the problem was I forgot to list the module in the list of modules the ng-app depends on.
I have faced this issue and it fixed with following way:
first remove ng-app from:
<html ng-app>
add name of ng-app to myApp:
<div ng-app="myApp">
add this line of code before function:
angular.module('myApp', []).controller('FirstCtrl',FirstCtrl);
final look of script:
angular.module('myApp', []).controller('FirstCtrl',FirstCtrl);
function FirstCtrl($scope){
$scope.data = {message: "Hello"};
}
In my case, this message comes from forgotten dependency injection in main module
This can happen if you have gulp misconfigured to add your angular app code more than once. In my case, this was in index.js, and it was adding it as part of the directory of js files (globbed in gulp) before and after my controller declarations. Once I added an exclusion for index.js not to be minified and injected the second time, my app began to work. Another tip if any of the solutions above don't address your problem.
Firstly - If the module name is not defined, in the JS you will not be able to access the module and link the controller to it.
You need to provide the module name to angular module.
there is a difference in using defining module as well
1. angular.module("firstModule",[])
2. angular.module("firstModule")
1 - one is to declare the new module "firstModule" with no dependency added in second arguments.
2 - This is to use the "firstModule" which is initialized somewhere else and you're using trying to get the initialized module and make modification to it.
i faced this issue but i was able to correct this issue by renaming the controller, please have a try on it.
ctrlSub.execSummaryDocuments = function(){};
sometimes something wrong in the syntax of the code inside the function throws this error. Check your function correctly. In my case it happened when I was trying to assign Json fields with values and was using colon : to make the assignment instead of equal sign = ...
I had two controllers with the same name defined in two different javascript files. Irritating that angular can't give a clearer error message indicating a namespace conflict.
I am not sure about this tutorial but I had the same problem when I forgot to include the file into grunt/gulp minimization process.
grunt.initConfig({
uglify: {
my_target: {
files: {
'dest/output.min.js': ['src/input1.js', 'src/missing_controller.js']
}
}
}
});
Hope that helps.
Watch your letter casing too. I spent a good hour chasing this bug.
<section id="forgotpwd" ng-controller="ForgotPwdController">
while I name the controller
angular
.module('app')
.controller('ForgotpwdController', ForgotpwdController);
They all should be consistently named, in this case ForgotpwdController with lower case p.
