ive add the angular-router file the server found it but it keeps giving me this error
Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.6.5/$injector/modulerr?p0=task&p1=Error%3A%20…0Uc%20(http%3A%2F%2Flocalhost%3A3000%2Fangular%2Fangular.min.js%3A22%3A332)

my view code is
<html >
<head>
<title>
</title>
</head>
<body ng-app="task" ng-init="first = 1;">
<h1>Task List</h1>
<div ng-controller="ctrl">
<span>Values: {{first}}</span>
<input type="text" ng-model="first" />
</div>
<script src="angular/angular.min.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script src="angular/app.js"></script>
</body>
</html>
my app.js code
var task = angular.module('myApp', ['ngRoute']);
task.controller('ctrl', function($scope){
$scope.first = 1;
});
please help.
The error message clearly states:
Failed to instantiate module task due to:
Error: …0Uc (http://localhost:3000/angular/angular.min.js:22:332)
The module name needs to match the name used in the ng-app directive:
<body ng-app="task" ng-init="first = 1;">
//var task = angular.module('myApp', ['ngRoute']);
var task = angular.module('task', ['ngRoute']);
task.controller('ctrl', function($scope){
$scope.first = 1;
});
Think you might need to rewrite that app.js code slightly:
task.controller('ctrl', ['$scope', function($scope) {
$scope.first = 1;
}]);
Why initialise first here in the controller when you're also doing it in the template, btw? Was there a reason?
Also you can do like this
var task = angular.module('myApp', ['ngRoute']);
task.controller('ctrl', taskCtrl);
function taskCtrl($scope){
// your logic here
}
Also move your ng-app tag to separate div and below it put JS script tags

Problem with ng-controller : Error: [$controller:ctrlreg] http://errors.angularjs.org/1.7.8/$controller/ctrlreg?p0=ListDataCtrl
I'm beginner in AngularJS, i'm facing a problem while using ng-controller :
this is my code :
<html>
<head>
<title></title>
</head>
<body ng-app>
<div ng-controller="ListDataCtrl">
<div ng-repeat="item in listData">
<p><strong>{{item.name | uppercase}}</strong></p>
<p>{{item.country}}</p>
<p>*********************</p>
</div>
</div>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.8/angular.min.js"></script>
<script>
function ListDataCtrl($scope){
$scope.listData =[
{"name":"Achraf", "country":"Tunisia"},
{"name":"Maher", "country":"UAE"},
{"name":"Ahmed", "country":"USA"},
{"name":"Issam", "country":"France"}
];
}
</script>
</body>
</html>
the error message is : angular.js:15567 Error: [$controller:ctrlreg] http://errors.angularjs.org/1.7.8/$controller/ctrlreg?p0=ListDataCtrl
The error indicated that controller is not registered:
The controller with the name 'ListDataCtrl' is not registered.
From AngularJS version 1.3 you have to register your controllers with modules rather than exposing them as globals:
documentation
First of all you need to declare an angularJS module for the app , and then register the controller to that module as below:
<body ng-app="myApp">
In script, app declaration:
var myApp = angular.module('myApp', []);
controller setup:
myApp.controller('ListDataCtrl', ['$scope', function($scope) {
...
}
This is my Html. I have given paths like this
<html>
<head>
<script src="../../Content/Scripts/Script/angular.min.js"></script>
<script src="../../Content/Scripts/Script/Chart.js"></script>
<script src="../../Content/Scripts/Script/angular-charts.min.js"></script>
<script src="../../Content/Scripts/Script/ui-bootstrap-tpls.js"> </script>
<script src="../../Content/Scripts/Controllers/graphController.js"></script>
</head>
<body>
<div ng-app="app" ng-controller="financeAnalyticsController" class="support-section">
{{a}}
</div>
</body>
</html>
In my script I wrote
var app = angular.module("app", [ "chart.js","ui.bootstrap", "ui.bootstrap.typeahead",]);
app.controller('financeAnalyticsController', function ($scope, $http, $filter) {
$scope.a="testing";
});
When I am using in my application it is giving error
Uncaught Error: [$injector:modulerr]
How to solve this error?
I guess you are using a different version of angular-chart.js. Try using angularCharts instead of chart.js as the dependency module name, like so ...
var app = angular.module("app", ["angularCharts", "ui.bootstrap", "ui.bootstrap.typeahead"]);
app.controller('financeAnalyticsController', function($scope, $http, $filter) {
$scope.a="testing";
});
or, use this version of angular-chart.js
see a working example
Why am i getting an injection error?

JS
var myApp = angular.module('myApp',["firebase"]);
myApp.controller('Controller', ['$scope', function($scope) {

On the JS pane, click settings, and set the load type to No wrap - in <body>.
It probably wasn't working because the script was executed before your dependencies were loaded.
I'm trying to learn AngularJS and am creating my first page. I am encountering the error:
Error: $injector:nomod Module Unavailable (here)
I have three files:
/index.html
/js/app.js
/js/controllers/MainController.js
And they are as follows:
/index.html
<!doctype html>
<html>
<head>
<tilte>AngularJS Controllers</title>
<script src = "https://ajax.googleapis.com/ajax/libs/angularjs/1.4.4/angular.min.js"></script>
</head>
<body>
<div ng-app="myApp">
<h1>Controllers</h1>
<div ng-controller="MainController">
<p>{{ message }}</p>
<form ng-submit="updateMessage(newMessage)">
<input type="text" ng-model="newMessage">
<button type="submit">Update Message</button>
</form>
</div>
</div>
<!-- Modules -->
<script type="text/javascript" scr="js/app.js"></script>
<!-- Controllers -->
<script type="text/javascript" src="js/controllers/MainController.js"></script>
</body>
</html>
/js/app.js
var app = angular.module("myApp", []);
/js/controllers/MainController.js
app.controller('MainController', ['$scope', function($scope){
$scope.message = 'hello';
$scope.updateMessage = function(message){
$scope.message = message;
};
}]);
Where am I going wrong?
Avoid creating global variables like app for assigning the angular module. Instead angular provides a better syntax to set and get modules across multiple files.
App.js
(function() {
// IIFE (Immediately invoked Function Express) to wrap variables inside the function. it prevents polluting global namespace.
angular.module("myApp", []);
})();
MainController
(function() {
angular.module("myApp") // note [] is missing, it means we're getting a module
.controller('MainController', ['$scope', function($scope){
$scope.message = 'hello';
$scope.updateMessage = function(message){
$scope.message = message;
};
}]);
})();
It is a typo.
When you pull your app.js inside the html, you wrote scr instead of src.
See:
<!-- Modules -->
<script type="text/javascript" scr="js/app.js"></script>
I'm using Apache server to host an angular app.
This is the index.html:
<html>
<head>
<script src="/lib/angular/angular.js">
</head>
<script>
myapp = angular.module('myapp', []);
myapp.controller('indexCtrl', function($scope){
$scope.words = ['It','is','what','it','is']
});
</script>
<body ng-app="myapp">
<div ng-controller="indexCtrl">
<div ng-repeat="word in words">
{{word}}
</div>
</div>
</body>
</html>
When I hit the html from the browser, it shows a blank page with this error :
Uncaught Error: [$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.
What could be wrong?
The error is because of duplicate values inside array. I have added track by $index inside ng-repeat to resolve this issue.
DOCS: ng-repeat
Modified code:
<html>
<head>
<script src="/lib/angular/angular.js"></script>
</head>
<script>
var myapp = angular.module('myapp', []);
myapp.controller('indexCtrl', function($scope){
$scope.words = ['It','is','what','it','is']
});
</script>
<body ng-app="myapp">
<div ng-controller="indexCtrl">
<div ng-repeat="word in words track by $index">
{{word}}
</div>
</div>
</body>
</html>
Please include angularjs in body.
<script src="/lib/angular/angular.js">
Include this line in body. Hope it will works!
Put the <script> part and the end of the body :
<body ng-app="myapp">
<div ng-controller="indexCtrl">
<div ng-repeat="word in words">
{{word}}
</div>
</div>
<script>
myapp = angular.module('myapp', []);
myapp.controller('indexCtrl', function($scope){
$scope.words = ['It','is','what','it','is']
});
</script>
</body>
that's a good practicte in HTML, and particularly in Angular to put the definition of your JS file just before the body ended
