Angularjs MVC tutorial


AngularJS MVC:

AngularJS mvc framework provides the facility to build flexible and loosely coupled applications. MVC stands for Model-View-Controller design pattern which separates the business logic, presentation logic and navigation logic.

Where:

Model: is responsible for encapsulating the application data.
View: is responsible for rendering the model data.
Controller: is responsible for receiving the user request, building model object and passing the model object to the view.

Example Explanation:

First include the AngularJS library in the application. The ng-app directive initializes the application. The ng-model directive binds the state of the input text to the respective name variables (student.firstName and student.lastname). The ng-controller=”appController” directive defines the controller. The appController defined as a JavaScript object with $scope as argument. The $scope.student is property of appController object. In $scope.student.fullName we are getting the combined name (firstName + lastName).
 
Note: We can also store controllers in external files .JS file and refer that file in the html page.

Example:

<html>
 
   <head>
    <title>Angular MVC Example</title>
    <script src = 
     "http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js">
    </script>
   </head>
 
   <body>
      <h2>AngularJS MVC Example</h2>
 
      <div ng-app = "testApp" ng-controller = "appController">
         Enter first name: 
         <input type = "text" ng-model = "student.firstName">
         <br><br>
         Enter last name: 
         <input type = "text" ng-model = "student.lastName">
         <br><br>
 
        Entered Value: {{student.fullName()}}
      </div>
 
      <script>
         var mainApp = angular.module("testApp", []);
 
         mainApp.controller('appController', function($scope) {
            $scope.student = {
               firstName: "Vivek",
               lastName: "Solenki",
 
               fullName: function() {
                  var studentObject;
                  studentObject = $scope.student;
                  return studentObject.firstName + " "
                                + studentObject.lastName;
               }
            };
         });
      </script>
 
   </body>
</html>
