Controller Methods

The example above demonstrated a controller object with two properties: lastName and firstName.

Additionally, a controller can also include methods (functions stored as variables).

AngularJS Example

<div ng-app=”myApp” ng-controller=”personCtrl”>

First Name: <input type=”text” ng-model=”firstName”><br>
Last Name: <input type=”text” ng-model=”lastName”><br>
<br>
Full Name: {{fullName()}}

</div>

<script>
var app = angular.module(‘myApp’, []);
app.controller(‘personCtrl’, function($scope) {
$scope.firstName = “John”;
  $scope.lastName = “Doe”;
  $scope.fullName = function() {
    return $scope.firstName + ” “ + $scope.lastName;
  };
});
</script>

Controllers In External Files

Controllers in external files are JavaScript functions defined outside of the main HTML document, allowing for better organization, modularity, and maintainability of AngularJS applications.
