# AngularJS Controller
|
||
|
|
------
|
||
|
|
Controllers are the behavior behind the DOM elements. AngularJS lets you express the behavior in a clean readable form without the usual boilerplate of updating the DOM, registering callbacks or watching model changes. (more info @ [https://angularjs.org/](https://angularjs.org/)
|
||
|
|
|

|
|
Example
|
||
|
|
```html
|
||
|
|
<div ng-app="myApp" ng-controller="myCtrl">
|
||
|
|
|
||
|
|
First Name: <input type="text" ng-model="firstName"><br>
|
||
|
|
Last Name: <input type="text" ng-model="lastName"><br>
|
||
|
|
<br>
|
||
|
|
Full Name: {{firstName + " " + lastName}}
|
||
|
|
|
||
|
|
</div>
|
||
|
|
|
||
|
|
<script>
|
||
|
|
var app = angular.module('myApp', []);
|
||
|
|
app.controller('myCtrl', function($scope) {
|
||
|
|
$scope.firstName = "John";
|
||
|
|
$scope.lastName = "Doe";
|
||
|
|
});
|
||
|
|
</script>
|
||
|
|
```
|
||
|
|
The ng-controller directive defines the application controller.
|
||
|
|
|
||
|
|
A controller is a JavaScript Object, created by a standard JavaScript object constructor.
