You should create and angular module first with name myApp then you could have data-ng-controller="SimpleController" to be move it over body tag so that the namek input field included inside the SimpleController controller context.
Add ng-app="myApp" on the body tag. so that angular module gets initialize on page.
Markup
<body data-ng-controller="SimpleController">
checkNames:
<input type="text" data-ng-model="namek">
<div class="container">
<ul>
<li data-ng-repeat="cast in castomers | filter:namek">{{cast.name|uppercase}} - {{cast.city}}</li>
</ul>
</div>
</div>
Controller
angular.module('myApp', []).controller('SimpleController', SimpleController);
function SimpleController($scope) {
$scope.castomers = [{
name: 'krishnendu sarkar',
city: 'kolkata'
}, {
name: 'chanchal sarkar',
city: 'bangalore'
}, {
name: 'nilava chakraborty',
city: 'pune'
}]
};
Demo PLunkr

please see this link here to see the whole code.
You should create angular module "myApp" which define the application then controller inside it.

Angular not working

I'm new to angular and want to start practicing some code. I created a simple app but the angular expression is not evaluating in the browser. My {{inventory.product.name}} prints to the browser as {{inventory.product.name}}; however, if I go to view page source my angular.min file is loaded. Can someone please tell me what I'm doing wrong, thanks.
HTML CODE
<title>Angular Practice</title>
<link rel="stylesheet" href="bootstrap/css/bootstrap.min.css">
</head>
<body ng-app="inventory">
<div ng-controller="InventoryController as inventory">
<h1>{{inventory.product.name}}</h1>
<h2>Product Amount</h2>
<p>Product description</p>
</div>
<script type="text/javascript" src="js/angular.min.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</body>
</html>
ANGULAR CODE
(Function(){
var app = angular.module('inventory', []);
app.controller('InventoryController', function(){
this.product = item;
});
var item = {
name: 'Test Item',
amount: 10,
description: 'This is the first test item',
}
})();
In your JS code, Function() should be function(). Note that Javascript is case sensitive.
Working code snippet:
(function() {
var app = angular.module('inventory', []);
app.controller('InventoryController', function() {
this.product = item;
});
var item = {
name: 'Test Item',
amount: 10,
description: 'This is the first test item',
}
})();
<body ng-app="inventory">
<div ng-controller="InventoryController as inventory">
<h1>{{inventory.product.name}}</h1>
<h2>Product Amount</h2>
<p>Product description</p>
</div>

Angularjs - Fill a comboBox dynamically(Array())

Thank you in advance

it seems your angularjs reference is wrong. please check the path. see below snippet with CDN.

Angular JS scope variable not working

Learning to use angularJS,
I have this particular code in my index.html. Dynamic typing works in the upper part, but the injection doesn't. What possibly might have been gone wrong?
Code :
<!DOCTYPE html>
<html>
<head>
<title>Test1</title>
</head>
<body ng-app="">
<!-- Dynamic Type -->
<input type="text" ng-model="name1" /><br>
<h1>Hello {{name1}}</h1>
<!-- End dynamic Type -->
<!-- Scope Injection begin-->
<div class="container" ng-controller="myController">
<input type="text" ng-model="naam" /><br>
<h3>Looping</h3>
<ul>
<li data-ng-repeat="cust in customerlist | filter:naam | orderBy:'city'"> {{cust.name | uppercase}} - {{cust.city}} </li>
</ul>
</div>
<script type="text/javascript" src="js/angular.min.js"></script>
<script type="text/javascript">
function myController ($scope) {
$scope.customerlist = [
{name: 'Raj Bannerjee', city: 'Zaire'},
{name: 'Prasun Bannerjee', city: 'Udaipur'},
{name: 'Raj Malhotra', city: 'Dubai'},
{name: 'Prasun Joshi', city: 'Mumbai'}
];
}
</script>
</body>
</html>
From version 1.3 angular disabled using global controller constructors:
https://github.com/angular/angular.js/commit/3f2232b5a181512fac23775b1df4a6ebda67d018
With the exception of simple demos, it is not helpful to use globals
for controller constructors. This adds a new method to
$controllerProvider to re-enable the old behavior, but disables this
feature by default.
BREAKING CHANGE: $controller will no longer look for controllers on
window. The old behavior of looking on window for controllers was
originally intended for use in examples, demos, and toy apps. We found
that allowing global controller functions encouraged poor practices,
so we resolved to disable this behavior by default.
So you must refactor it like so:
angular.module('app',[])
.controller('myController', ['$scope', function($scope) {
$scope.customerlist = [
{name: 'Raj Bannerjee', city: 'Zaire'},
{name: 'Prasun Bannerjee', city: 'Udaipur'},
{name: 'Raj Malhotra', city: 'Dubai'},
{name: 'Prasun Joshi', city: 'Mumbai'}
];
}]);
And also refer to your module:
<body ng-app="app">

why angularjs ng-repeat not working

I am trying out the basics of AngularJS first time. I am trying out ng-repeat first time. However it is not working.
Here is a non working jsfiddle.
I have written the code in single standalone HTML file as follows and also angular.js file resides in the same directory
<html ng-app>
<head>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript">
var users = [
{
name:"Mahesh",
description:"A geek",
age:"22"
},
{
name:"Ganesh",
description:"A nerd",
age:"25"
},
{
name:"Ramesh",
description:"A noob",
age:"27"
},
{
name:"Ketan",
description:"A psychopath",
age:"26"
},
{
name:"Niraj",
description:"Intellectual badass",
age:"29"
}
];
</script>
</head>
<body>
<div>
<div data-ng-repeat="user in users">
<h2>{{user.name}}</h2>
<div>{{user.description}}</div>
</div>
</div>
</body>
</html>
users must refer to a property that is accessible on the current scope. Scopes are AngularJS way of tying data from and to HTML. This is explained further in the "Model and Controller" chapter of the second tutorial page. See a working version of your Fiddle here.
HTH!
you have not define the controller such as
myapp.controller("AppController",function($scope){
$scope.users=[
{
name:"Mahesh",
description:"A geek"
},
];
});
/// than you can call controller to the view such as below code :
<body ng-controller="AppController">
<div><div data-ng-repeat="user in users">
<h2>{{user.name}}</h2>
<div>{{user.description}}</div>
</div>
</div>
</body>
Live Example you can access by this link : http://jsfiddle.net/9yHjj/
Your code should have been like this....
<html ng-app="app">
<head>
<script type="text/javascript" src="angular.js"></script>
<script type="text/javascript">
var app = angular.module("app",[]).controller(AppController,["$scope",function($scope){
$scope.users=[
{
name:"Mahesh",
description:"A geek",
age:"22"
},
{
name:"Ganesh",
description:"A nerd",
age:"25"
},
{
name:"Ramesh",
description:"A noob",
age:"27"
},
{
name:"Ketan",
description:"A psychopath",
age:"26"
},
{
name:"Niraj",
description:"Intellectual badass",
age:"29"
}
];
}])
</script>
</head>
<body ng-controller="AppController">
<div>
<div data-ng-repeat="user in users">
<h2>{{user.name}}</h2>
<div>{{user.description}}</div>
</div>
</div>
</body>
</html>
<html ng-app="myapp1">
<head>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script type="text/javascript">
var myapp = angular.module("myapp1",[]);
myapp.controller("AppController",function($scope){
$scope.users=[
{
name:"Mahesh",
description:"A geek",
age:"22"
},
{
name:"Ganesh",
description:"A nerd",
age:"25"
},
{
name:"Ramesh",
description:"A noob",
age:"27"
},
{
name:"Ketan",
description:"A psychopath",
age:"26"
},
{
name:"Niraj",
description:"Intellectual badass",
age:"29"
}
];
});
</script>
</head>
<body ng-controller="AppController">
<div>
<div data-ng-repeat="user in users">
<h2 ng-bind="user.name"></h2>
<div>{{user.description}}</div>
</div>
</div>
</body>
</html>
This code should work

AngularJS module doesn't load

My module isn't loading, and I can't figure out why. Could someone help me to find out what I am doing wrong?
The following is my HTML in a file named index.html:
<html ng-app="demoApp">
<head>
<title>Using AngularJS Directives and Data Binding</title>
<script type="text/javascript" src="_Script.js"></script>
<script src="angular.min.js"></script>
</head>
<body>
<!-- Get name out of array with controller using a module-->
<h3>Get names out of an array with controller using a module:</h3>
<div class ="container" ng-controller="SimpleController">
<input type="text" ng-model="search" /> {{ search }}
<ul>
<li ng-repeat="naam in namen | filter:search" >{{ naam }}</li>
</ul>
</div>
</body>
</html>
And this is the Javascript in a file named _Script.js:
var demoApp = angular.module('demoApp', []);
function SimpleController($scope) {
$scope.namen = [
'John',
'Will',
'Alex'
];
}
demoApp.controller('SimpleController', SimpleController);
I've looked for everything, so maybe it is simple. But I can't find it and got stuck with it.
Regards,
You're currently loading your _script.js first, and angular JS second. If you reorder them your script should work:
