AngularJS - Understanding Controllers

Main task of Controllers in AngularJS is to control the data in AngularJS .

As we know that AngularJS is the depends on Javascript so you may find syntax same as JavaScript derived .

Normally it will be called by JavaScript Object constructor .

You will be more familiar after executing following code :

<html>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<body>

<!-- Main Code For Two Inputs   -->
<div ng-app="Manav" ng-controller="Ctrl">
City: 
<input type="text" ng-model="city"><br><br><br>
Country: 
<input type="text" ng-model="country"><br><br><br>
Result: {{city + " " + country}}
</div>
 
<!-- Function Ceated For Two Object -->
<script>
var app = angular.module('Manav', []);
app.controller('Ctrl', function($scope) {
    $scope.city = "Rajkot";
    $scope.country = "India";
});
</script>
 
</body>
</html>

As you can see above example :
