I have come across a lot of similar issues here on SF and did everything as expected. Yet, I can't seem to get this simple Angular app working. Console throws up this exception
angular.min.js:6 Uncaught Error: [$injector:modulerr]
AngularJS site docs gave some suggestions which I followed. Yet, I still get that same exception. Here is my code.
<!DOCTYPE html>
<html lang="en" ng-app="myApp">
<head>
<meta charset="utf-8">
<title>Dead Simple Proj</title>
<link rel="stylesheet" href="content/css/styles.css">
<script scr="app\app.js"></script>
<script src="app\lib\angular.min.js"></script>
</head>
<body>
<div ng-controller="GreetingController">
{{ greeting }}
</div>
</body>
</html>
I have this in the App.js
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});
I double checked file paths and other possibly obvious mistakes, but no joy.
I am definitely missing out something here? Thanks.
Your paths referencing the libraries and the app.js are wrong and in the wrong order . You should load the angular reference first and then the relative js referencing the module.
Change
From
<script scr="app\app.js"></script>
<script src="app\lib\angular.min.js"></script>
To
<script src="app/lib/angular.min.js"></script>
<script scr="app/app.js"></script>
DEMO
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});

I dont think you added your angular files properly. I made a plunker out of your code and it worked. you can cross check with my code.
var myApp = angular.module('myApp', []);
myApp.controller('GreetingController', function($scope) {
$scope.greeting = 'Hola!';
});
<html ng-app="myApp">
<head>
<script data-require="angular.js#1.6.2" data-semver="1.6.2" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.2/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="GreetingController">
<h1>Hello {{greeting}}!</h1>
</body>
</html>

Where is the ng-app name ? Provide module name.
angular.module('myApp',[])
.controller('SomeCtrl',function($scope){ .. your code ...})
Provide it in .html file
<html ng-app="myApp">
Fixed your Plunkr
You are referring to older version of AngularJS for learning and using 1.5 in plunkr. Check the below link
For your app, refer
this link
and this one too
While your code may be correct, but it is prior to the versions 1.3.0
Versions Before 1.3.0:
Prior to 1.3.0, angular was able to automatically discover controllers
that were defined globally.
Check Below I have created without module
<div ng-app>
<div ng-controller="MainController">
{{message}}
</div>
</div>
The code can be:
var MainController = function($scope) {
$scope.message = "Hello";
};
<!DOCTYPE html>
<html ng-app>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.32/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}} </h1>
</body>
</html>
Plunker version prior to 1.3.0
Versions After 1.3.0:
You can use $controllerProvider.allowGlobals() to enable that behaviour.
allowGlobals allows $controller to find controller constructors on
window
angular.module("ng").config(function($controllerProvider){
$controllerProvider.allowGlobals();
});
var MainController = function($scope) {
$scope.message = "Hello";
};
<!DOCTYPE html>
<html ng-app>
<head>
<link rel="stylesheet" href="style.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.5.8/angular.js"></script>
<script src="script.js"></script>
<script type="text/javascript">
function MyController() {}
</script>
</head>
<body ng-controller="MainController">
<h1>{{message}} </h1>
</body>
</html>
Plunker with versions after 1.3.0
Note: I personally recommend to use the latest versions with modules
and ng-app="app" format.
angular.module('myApp',[])
.controller('MainController',function($scope){ .. your code ...})
Here you go!!

Here i try to Angular setup in html page for that i wrote simple code as Below
MyApp.js
/// <reference path="angular.js" />
var app = angular.module('MyApp', [])
debugger;
app.controller('HomeCtrls', function ($scope) {
$scope.msg = "This is MyApp....";
})
Master.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head ng-app="MyApp">
<title></title>
<script src="../../Script/angular.js"></script>
<script src="../../Script/MyApp.js"></script>
</head>
<body ng-controller="HomeCtrls">
{{msg}}
</body>
</html>
Here why my msg is not Loading This is MyApp....
ng-app inject wrong place. Not <head ng-app="MyApp">, Inject html or body or div tag as per your web application need.
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script src="../../Script/angular.js"></script>
<script src="../../Script/MyApp.js"></script>
</head>
<body ng-app="MyApp" ng-controller="HomeCtrls">
{{msg}}
</body>
</html>
the problem is with your angular script, is not loaded, check your path, you can use the CDN also :
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
I am new in angularjs, so i try this script in Index.html like this:
<!DOCTYPE html>
<html lang="en" ng-app="DEMO">
<head>
<title></title>
</head>
<body>
<h1 ng-controller="HelloWorldCtrl">{{HelloMessage}}</h1>
<script src="angular.min.js"></script>
<script type="text/javascript">
function HelloWorldCtrl($scope) {
$scope.HelloMessage = "Hello Pejman";
}
</script>
</body>
</html>
but when i run this, it show {{HelloMessage}} instead of Hello Pejman , what is the problem?
EDIT : this is the tutorial:
You did not bootstrap angular module, that is why your code doesnt work. You must call ng-app in any HTML tag to notify Angular start in there. So all of the sub tags under the tag Angular declared will be able to use directives, scope, controller etc.
Please check here to understand how to create controller and use it : https://docs.angularjs.org/guide/controller
Try this:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Hello World</title>
<script src="angular.min.js"></script>
</head>
<body>
<h1 ng-app="demo" ng-controller="HelloWorldCtrl">{{HelloMessage}}</h1>
<script type="text/javascript">
var app = angular.module('demo', []);
app.controller('HelloWorldCtrl', function($scope) {
$scope.HelloMessage = "Hello Pejman";
});
</script>
</body>
</html>
I'm trying to make my AngularJS HelloWorld work but I can't. My code is the following:
<!DOCTYPE html>
<html np-app="myApp">
<head>
<meta charset="UTF-8">
<title>Angular Test</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script>
var app = angular.module("myApp",[]);
app.controller("appCtrl",function($scope){
$scope.mensagem="HelloWorld!";
});
console.log(angular);
console.log(app);
</script>
</head>
<body>
<div ng-controller="appCtrl">
{{mensagem}}
</div>
</body>
The output:
{{mensagem}}
I searched about similar questions here in SO but found only questions with a missing ng-app atribute.
I tried opening my file both in Firefox and Chrome and I get the same error. Logging both angular and app reveal that they are both defined.
I don't know what I'm doing wrong.
In your HTML tag, you've misspelled ng-app, which is probably the main reason it's not working. You should also place the include for Angular down at the end of the body, which ensures the app and controller elements are defined before the script runs:
<html ng-app="myApp">
<head>
<meta charset="UTF-8">
<title>Angular Test</title>
</head>
<body>
<div ng-controller="appCtrl">
{{mensagem}}
</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script>
var app = angular.module("myApp",[]);
app.controller("appCtrl",function($scope){
$scope.mensagem="HelloWorld!";
});
console.log(angular);
console.log(app);
</script>
</body>
</html>
I am following a tutorial but stuck on one issue. I don't know what I am missing here.
//script.js
var MainController = function($scope)
{
$scope.message = "Hello!!!!";
};
<!-- index.html -->
<!DOCTYPE html>
<html ng-app>
<head>
<script data-require="angular.js#1.3.4" data-semver="1.3.4" src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
Problem is -
The message is not binding.
Create your module first, then add the controller to the module, specify both the app and controller in your HTML portion.
<!DOCTYPE html>
<html ng-app="app">
<head>
<script data-require="angular.js#1.3.4" data-semver="1.3.4" src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.4/angular.min.js"></script>
<script>
var app = angular.module('app',[]);
var MainController1 = function($scope)
{
$scope.message = "Hello!!!!";
};
app.controller("MainController1", MainController1);
</script>
</head>
<body ng-controller="MainController1">
<h1>{{message}}</h1>
</body>
</html>
