- In Angular JS Controller is the Javascript constructor function.
- When directive ng-controller is added to the DOM, Angular create a constructor function to the controller.
- And creates variable $scope to the respective controller.
<body ng-app="myApp">
<div ng-controller="myController"> {{message}} <br />
<input type="text" ng-model="sqr" ng-init="sqr=5"> Square of <b>{{sqr}}</b> = {{square(sqr)}}
</div>
</body>
<script>
var myApp = angular.module('myApp',[]);
myApp.controller('myController', ['$scope', function($scope) {
//Property to the scope
$scope.message = 'Hello!';
//Behaviour to the scope
$scope.square = function(v) {
return v * v;
};
}]);
</script>
