AngularJS Data Binding

Data binding in AngularJS is the synchronization between the model and the view.

Data Model

AngularJS applications usually have a data model. The data model is a collection of data available for the application. Data binding is a very powerful feature of the software development technologies. Data bind is the connection bridge between view and business logic (view model) of the application. Data binding in AngularJs is the automatic synchronization between the model and view. When the model changes, the view is automatically updated and vice versa. AngularJs support one-way binding as well as two-way binding.


var app = angular.module('myApp', []);
<br>app.controller('myCtrl',&nbsp;function($scope) {<br>&nbsp;
AngularJS: Developer Guide: Data Binding


The HTML container where the AngularJS application is displayed, is called the view. The view has access to the model, and there are several ways of displaying model data in the view. You can use the ng-bind directive, which will bind the innerHTML of the element to the specified model property:


&lt;p ng-bind="firstname">&lt;/p>

You can also use double braces {{}} to display content from the model:


&lt;p>First name: {{firstname}}&lt;/p>

Or you can use the ng-model directive on HTML controls to bind the model to the view.

The ng-model Directive

Use the ng-model directive to bind data from the model to the view on HTML controls (input, select, textarea)


&lt;input ng-model="firstname">

The ng-model directive provides a two-way binding between the model and the view.

Two-way Binding

Data binding in AngularJS is the synchronization between the model and the view. When data in the model changes, the view reflects the change, and when data in the view changes, the model is updated as well. This happens immediately and automatically, which makes sure that the model and the view is updated at all times.


&lt;div ng-app="myApp" ng-controller="myCtrl"><br>  Name:
 &lt;input ng-model="firstname"><br>  &lt;
/h1><br>&lt;/div> &lt;script><br>var app = angular.module('myApp', []);
<br>app.controller('myCtrl', function($scope) {<br>  $scope.firstname = "John";<br>  $scope.lastname = "Doe";<br>});&lt;/script>

AngularJS Controller

Applications in AngularJS are controlled by controllers. Read about controllers in the AngularJS Controllers chapter. Because of the immediate synchronization of the model and the view, the controller can be completely separated from the view, and simply concentrate on the model data. Thanks to the data binding in AngularJS, the view will reflect any changes made in the controller.


&lt;div ng-app="myApp" ng-controller="myCtrl"><br>  &lt;
h1 ng-click="changeName()">{{firstname}}&lt;
/div> script><br>var app = angular.module('myApp', []);
<br>app.controller('myCtrl', function($scope) {<br>  $scope.firstname = "John";<br>  $scope.changeName = function() {<br>    $scope.firstname = "Nelly";<br>  }<br>});<br>&lt;/script>

Why AngularJs is the Most Popular Framework

1) User Interface

The framework depends on HTML to make the best UI for web and application clients. If you are searching for an approach to creating a fantastic UI, AngularJS is your go-to solution prepared to do effectively conveying this task. This enables the engineer to build lightweight, however user-friendly applications.

Many times, it becomes complex to create, organize, and rearrange the JavaScript Interfaces. Along these lines, the HTML interface can also control the execution of the application. So rather than, as opposed to understanding project stream and loading, you can characterize what you need, and AngularJS will carve out the dependencies.

2) Two Way Data-Binding

The two-way information restricting usefulness in AngularJs is very commendable. As a piece of it, any progressions that occur in the application affect the UI and the other vice-versa. With the AngularJs framework, the user actions and module changes happen all the while.

With two-way data binding, the application’s presentation layer turns out to be very simple. Accordingly, the UI is clean and has an improved intrigue. Also, complex data manipulation and calculations can be possible easily.

AngularJS Development is two-way data-mining manage the synchronization in the DOM and the model, just as the other way around making things simpler for developers utilizing AngularJS for development.

3) Dealing with MVC

AngularJS slot in the basic standards behind the original MVC software design into how it creates customer side web applications. AngularJS Development doesn’t execute Model-View-Controller (MVC) in the conventional sense, yet rather something closer to MVVM (Model-View-View Model).

MVC makes it simpler to fabricate a different client-side application. With AngularJS, regardless of whether the MVC elements were grown independently, you can combine them. There is no need to write additional code to join all the attributes together.

4) Fast and Easy to Adopt

With Angularjs-JavaScript MVC Framework, it is straightforward to start front-end development. For the most part, to build up an application in a minute, you need to add a few attributes to the HTML language, and there you go with significant development.

This framework improves HTML and effectively executes every one of the assignments from accessible to complex tasks, helping to pull out the controller function. Additionally, it permits building dependency among controller and layout.

5) POJO Model

When compared with other frameworks, AngularJS utilizes POJO (Plain Old JavaScript Objects). Presently, that implies you don’t have to include extra getter and setter components to tie AngularJS alongside additional information sources. A POJO model also gives natural and well-arranged objects. Designers need to make create loops and loops of exhibits with the necessary properties. At that point, they have to modify and reframe it.

6) Filter

Filters play a significant role in the development procedure, as they serve to organize stored data. With AngularJS web development, you can depend on various channels, for example, Number, Lowercase, Uppercase, OrderBy, and many more. This is exceptionally commonsense when displaying enormous lumps of information to a client, or for the making of the database search usefulness.


Cross-browser web applications built utilizing AngularJS Development are user-friendly and interactive. One more advantage of AngularJS Development is that it investigates the page DOM and afterward manufactures ties that depend on AngularJS-specific elements. There are several critical things to take into consideration with regards to picking Angular. Angular can settle on building dynamic and endeavor prepared web applications.

Google backs Angular and supports it with a massive open network. You can have confidence that every component will be progressively improved with time for superior performance.
