Angular JS
is an open source JavaScript framework that's wont to build web applications. Angular
Js is developed by Google.
It is a
superb framework for building single part applications and line of business
applications.
Advantage
of AngularJS
There are
plenty of JavaScript frameworks for building web applications. So, it's a
genuine question, why to use Angular JS.
Following are the benefits of
AngularJS over different JavaScript frameworks:
·
Dependency
Injection: Dependency Injection specifies a style pattern during AngularJS
Training in Marathahalli which parts are given their dependencies
instead of onerous secret writing them within the part.
·
Two
approach information binding: AngularJS creates a 2 approach data-binding
between the choose component and also the order Prop model. Order Prop is then
used because the input for the order by filter.
·
Testing:
Angular JS is meant in a approach that we can test right from the beginning.
So, it's terribly simple to test any of its elements through unit testing and
end-to-end testing.
·
Model
view Controller: In Angular JS, it's terribly simple to develop application
during a clean MVC approach. You only need to split your application code into
MVC elements i.e. Model, view and also the Controller.
·
Directives,
filters, modules, routes etc.
AngularJS
MVC architecture
MVC stands
for Model view Controller. It’s a software design pattern for developing web
applications. It’s very hip as a result of it isolates the applying logic from
the interface layer and supports separation of issues.
The MVC pattern is created of the
following 3 parts:
1.
Model:
it's responsible for managing application information. It responds to the
requests from view and to the directions from controller to update itself.
2.
View:
it's responsible for displaying all data or only some of data to the users. It
also specifies the info in a specific format triggered by the controller's call
to present the information. They’re script-based template systems like JSP,
ASP, PHP and really simple to integrate with Ajax technology.
3.
Controller:
it's responsible to manage the relation between models and views. It responds
to user input and performs interactions on the info model objects. The
controller receives input, validates it, and then performs business operations
that modify the state of the info model.
AngularJS
data binding
Data binding
could be a terribly helpful and powerful feature used Angular
Training in Marathahalli with placement in software development
technologies. It acts as a bridge between the view and business logic of the
applying.
AngularJS
follows Two-Way data binding model.
One-Way
data binding
The one-way
data binding is an approach wherever a value is taken from the data model and
inserted into an HTML component. There’s no way to update model from view. it's
utilized in classical template systems. These systems bind data in just one
direction.
Two-Way
data binding
Data-binding
in Angular apps is that the automatic synchronization of data between the model
and look at parts.
Data binding
allows you to treat the model because the single-source-of-truth in your
application. The view could be a projection of the model in the least times. If
the model is modified, the view reflects the change and the other way around.
AngularJS
Directives
AngularJS
facilitates you to increase HTML with new attributes. These attributes are
known as directives.
There is a
group of built-in directive in AngularJS that offers practicality to your
applications. You can also outline your own directives.
Directives
are special attributes beginning with ng- prefix. Following area unit the
foremost common directives:
·
ng-app:
This directive starts an AngularJS Application.
·
ng-init:
This directive initializes application information.
·
ng-model:
This directive defines the model that's variable to be utilized in AngularJS.
·
ng-repeat:
This directive repeats HTML parts for every item during a collection.
