I am using WAMP and under my www folder i have a folder called ng-cribs.
the index has the following code
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.2/angular.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/2.5.0/ui-bootstrap-tpls.min.js"></script>
<script src="app.js"></script>
<script src="scripts/cribsController.js"></script>
<head>
<title>ng-cribs</title>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" integrity="sha384-WskhaSGFgHYWDcbwN70/dfYBj47jz9qbsMId/iRN3ewGhXQFZCSftd1LZCfmhktB" crossorigin="anonymous">
</head>
<body ng-app="ngCribs" ng-controller="cribsController">
<h1> {{hello}} </h1>
</body>
</html>
Then i have a app.js file in the same folder with the following code
angular.module('ngCribs, ['ui.bootstrap']);
Then lastly a controller file under a new folder called scripts nad the file name is cribsController with the following code
angular
.module('ngCribs')
.controller('cribsController'), function(&scope){
$scope.hello = 'hello world!'
});
However my result is {{Hello}} instead of displaying what is in the controller
In the controller function, you must use $ instead of &.
angular
.module('ngCribs',[])
.controller('cribsController', function($scope){
$scope.hello = 'hello world!'
});
You should declare syntax as below
angular
.module('ngCribs').controller('cribsController', ['$scope', function($scope) {
$scope.hello = 'hello world!'
}]);
instead of
angular
.module('ngCribs')
Results in closing the controller without declaring its dependencies and
injections.
.controller('cribsController'), function(&scope){
$scope.hello = 'hello world!'
});

The index.html page looks like this.
<!DOCTYPE html>
<html ng-app>
<head>
<script type="text/javascript" src="/js/script.js"/>
<script data-require="angular.js#*" data-semver="1.3.0-beta.14" src="http://code.angularjs.org/1.3.0-beta.14/angular.js"></script>
<meta charset="UTF-8">
<title>Test Page</title>
</head>
<body ng-controller="MainController">
<div>
<h1>{{message}}</h1>
<div>
{{person.firstName}}
</div>
</div>
</body>
</html>
The script.js file looks like this:
var MainController = function($scope) {
var person = {
firstName : "Nagendra"
};
$scope.person = person;
$scope.message = "Hello Angular!";
};
But when I boot up the application my page shows :
{{message}}
{{person.firstName}}
and not the values that it should. Am I missing something here? I am using spring boot.
I have debugged the chrome and have seen the js file loading properly, it even hits the debugger point in the js file,hence the file loading is not the problem i suppose.
UPDATE- THIS WORKED
var MainController = function($scope) {
var person = {
firstName: "Nagendra"
};
$scope.person = person;
$scope.message = "Hello Angular!";
};
angular.module('mainApp', [])
.controller('MainController', MainController);
index.html

<html ng-app="mainApp">

Since angular 1.3+ global function declaration of controller haven't been supported. So you have first create an angular module and then bind all of its angular component to it.
Also move /js/script.js right after angular.js reference with closing </script> tag.
Code
angular.module('mainApp', [])
.controller('MainController', MainController)
function MainController($scope) {
var person = {
firstName: "Nagendra"
};
$scope.person = person;
$scope.message = "Hello Angular!";
};
Then do add mainApp module inside ng-app directive like ng-app="mainApp" on html tag.
Demo Here
You need to define the module and the controller,
HTML:
<body ng-app="DemoApp" ng-controller="DemoController">
{{message}} {{person.firstName}}
</body>
Controller:
var app = angular.module('DemoApp', ['angular.filter'])
app.controller('DemoController', function($scope) {
var person = {
firstName : "Nagendra"
};
$scope.person = person;
$scope.message = "Hello Angular!";
});

I have this main application called dashboard and I want to inject a custom made module called core.
I keep getting this injection error and I have no idea why. I am following a template that my co-worker has and it is pretty much word for word so I do not know why it is not working for me.
app.js
(function(){
'use strict';
var dependencies = [
'ngRoute',
'core'
]; // all our modules
angular.module('dashboard', dependencies).config(Config); //.config(Config);
Config.$inject = ['$locationProvider'];
function Config($locationProvider){
$locationProvider.hashPrefix('!');
}
angular.element(document).ready(function(){
angular.bootstrap(document, ['dashboard']);
});
})();

As you were using IIFE pattern for restricting the scope of code, you should invoke function of core.client.module.js immediately to core module get available.
core.client.module.js
(function(){
//---- code here-----//
})(); //<---invoke the function
I'm trying to learn Angular.js. I set up a simple page, in which I want to display a message from my script file. Here's the HTML structure:
<!DOCTYPE html>
<html ng-app>
<head>
<script data-require="angular.js#*" data-semver="2.0.0-alpha.31" src="https://code.angularjs.org/2.0.0-alpha.31/angular.js"></script>
<link href="style.css" rel="stylesheet" />
<script src="script.js"></script>
</head>
<body ng-controller="MainController">
<h1>{{message}}</h1>
</body>
</html>
And this is my script.js:
var MainController = function($scope){
$scope.message = "my message";
};
I'm supposed to see the words my message on the page, but instead I'm seeing literally {{message}}. I tried to wrap the JS code in self-envoking function:
(function() {
var MainController = function($scope) {
$scope.message = "my message";
};
}());
But it didn't have any result.
What am I doing wrong?
It's old syntax and you cannot declare controller like that. Now you need to register controller on your module.
angular.module('anyModuleName',[]).controller('yourControllerName',function(){
});
and also edit to ng-app="anyModuleName" where you initialize your app. In your case <html ng-app="anyModuleName">
I just saw a video of introduction to AngularJS and use the following example
The html:
<!DOCTYPE html>
<html ng-app>
<head lang="en">
<meta charset="UTF-8">
<title></title>
</head>
<body ng-controller="MainContrl">
<h2>{{message}}</h2>
<script src="bower_components/angular/angular.min.js"></script>
<script src="js/test.js"></script>
</body>
</html>
The js:
var MainContrl = function($scope){
$scope.message = "Hello friend";
};
In the example I've seen this structure works, but when I test it does not work.
The console gives me this error:
Error: [ng:areq] http://errors.angularjs.org/1.3.15/ng/areq?p0=MainContrl&p1=not%20a%20function%2C%20got%20undefined
Can be used in this way the controller?
Or is it a bad practice
Example in Plunker:
Code example
I think, it's a bad practice
You better use:
var myApp = angular.module('myApp', []);
myApp.controller('MainContrl', ['$scope', function ($scope) {
// any code here
]);
And use this in HTML:
<html ng-app="myApp">
<body ng-controller="MainContrl">
// any code here
</body>
</html>
You may need to define your angular App first :
var myApp = angular.module('myApp', []);
myApp.controller('MainContrl', function ($scope) {
$scope.message = "Hello friend";
});
here is a working example on Plunkr
I think you have to have a main app.
In myapp.js
var yourApp = angular.module('myApp',[]);
In mainController.js (it should not be called test.js)
yourApp.controller('MainController',['$scope',function($scope){
$scope.message = "Hello world";
}]);
In your index.html
<html ng-app="myApp">
<body ng-controller="MainController">
{{message}}
</body>'
<script src="bower_components/angular/angular.min.js"></script>
<script src="js/myapp.js"></script>
<script src="js/mainController.js"></script>
</html>
Change Your script.js to
var app=angular.module('myapp',[]);
app.controller('MainContrl', ['$scope', function($scope){
$scope.message = "Hello friend";
}]);
and in html page put ng-app in body tag and remove ng-app from html
<body ng-app="myapp" ng-controller="MainContrl">
First declare your app in your html:
<html ng-app="myApp">
Second define your app in your js:
var app = angular.module('myApp', []);
Then definewhatever controller in whatever js file (best practice sugests that every controller has its own file):
var MainContrl = function($scope){
$scope.message = "Hello friend";
};
Then declare your controller and variables in your html:
<body ng-controller="MainContrl">
<h2>{{message}}</h2>
</body>
Don't forget to bind your controller with your app:
app.controller('MainContrl',MainContrl);
I also can see that you're using bower, so I suggest you read this:

I have an AngularJS app. I want this app to run both in the browser and be able to distribute it with PhoneGap. In an attempt to do this, I have the following code:
index.html
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/app/app.js"></script>
</head>
<body>
...
<script type="text/javascript">
if (window.location.protocol === "file:") {
document.addEventListener('deviceready', startApp, false);
} else {
startApp();
}
</script>
</body>
</html>
app.js
function startApp() {
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function() {
...
});
myApp.run(function() {
...
});
}
controller.js
"use strict";
myApp.controller('MyController', function($rootScope, $scope, $location) {
...
});
myApp.controller('MyOtherController', function($rootScope, $scope, $location) {
...
});
...
If I add controllers.js after app.js in the head tag, I get an error that says:
Uncaught ReferenceError: myApp is not defined
This is happening because I'm manually bootstrapping the AngularJS app. I need to manually bootstrap it because of my need to startApp. For this reason, I need a way to dynamically load controllers.js from within startApp. Yet, I'm not sure how to do that. Can anyone provide some help?
THank you
you have missed ng-app="" attribute in html tag...
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script type="text/javascript" src="/app/app.js"></script>
</head>
<body>
...
<script type="text/javascript">
if (window.location.protocol === "file:") {
document.addEventListener('deviceready', startApp, false);
} else {
startApp();
}
</script>
</body>
</html>
Why don't you give requirejs a try?
He has a strong dependency management based loader and will avoid issues like this.
First thing first: To initialize your app angular module its require angular-route.js with angular.js file and these js file should be loaded before your app js.
<head>
<script type="text/javascript" src="/app/angular.js"></script>
<script type="text/javascript" src="/app/angular-route.js"></script>
<script type="text/javascript" src="/app/app.js"></script>
</head>
