AngularJS
is just superb, to not mention it's a JavaScript framework designed for web
developers and designers, who want to possess a lot of control over their web
Applications. How much a web designer would benefit from this framework, is
difficult to predict currently. However, if you're a web developer, this
feature rich framework can enable you to feature a lot of aspiring to you consumer
facet applications. Therefore, it's necessary to understand what features
AngularJS has got to supply and the way to use it in our applications.
01) MVC
architecture
The
first important feature is that the MVC or Model-View-Controller architecture. The
AngularJS
Training in Marathahalli thought behind exploitation this design
pattern (architecture) is to separate the web application into a more
manageable structure. The MVC architecture includes of 3 important parts, the
model, view and controller.
·
Model
o
The model is
wherever your data are. Either the data we are talking regarding is a static
data or dynamically fetched from a data supply, tucked in a server that's miles
away from the client, using JSON.
o
A model includes
of a simple JavaScript object called the scope. Tied to a controller, the model
object receives the information (from the source) and delivers it to a view
(HTML)
·
View
o
In Angular, the
view comprises of hypertext mark-up language elements and directives. This is
the section of application that is visible to users (using a browser). Apart
from markups, each view has as and with curled braces, that is bound to the
scope object.
o
Piece of markup,
additionally referred to as model in Angular, when bound, complied and loaded
on the browser is then referred to as the read.
·
Controller
o
The controller
really controls the complete business logic of your application. The initial
stage is set here, that is, it initializes and registers the application by
making a new Angular Module.
02) Two way
data binding
Angular
Data-Binding creates a link between model and view.
The
two-way data binding is a rare feature ever integrated in a JavaScript
framework. In two-way data binding, any change created within the view can
replicate in model, equally changes created within the model can replicate
within the view. It’s a two way process.
In
Angular, we want to use the ng-model directive to create a two-way data
binding. This directive can bind the model to the view. We'll do an example to
know the method better.
03) Templates
In
Angular, a template sometimes means a view with hypertext mark-up language
elements connected to Angular Directives , add markup for data binding using
expressions (with curled braces).
An
angular model appearance just about part of a markup, aside from its
attributes. To create it Angular
Training in Marathahalli with placement dynamic, but we want to add
a controller and a model.
Listed below are the elements and attributes
that make up the model.
·
Directive –the
ng-app and ng-model are directives.
·
Markup – Binding
the view with model exploitation the curled braces} (expressions) is that the
markup.
·
Filters – Filters
are helpful for data formatting the worth in an expression. It’s terribly
helpful.
·
Form Controls –
we can use Angular type Controls to validate user inputs.
04) Directives
Angular
Directives are attributes applied within the view. Connected to hypertext
mark-up language parts, the directives augment the weather with new behaviors. Every
component has directives, prefixed with ng-. Whenever we attach a directive
with an element, it tells AngularJS that it's a part of Angular app and Angular
treats it that way.
05)
Expressions
Angular
Expressions are JavaScript like expressions, but with much distinction. Written
within 2 curled braces, these expressions can bind Angular application data to
hypertext mark-up language elements.
06) Modules
In
the starting of this text whereas explaining regarding MVC, however the design
helps in coming up with Angular application by rending the app into very little
manageable structures. The Modules are pillar of this design. A module creates
a well-defined structure, which can keep everything organized, at one place.
A
single application could more than one module. By making a new module, every
application is 1st initialized and registered.
07) Scope
A
Scope is a JavaScript object that sits within the model, and delivers knowledge
to the view. The view’s expression can receive the value(s) from the $scope and
show the result precisely wherever the expression is found.
08) Filters
We
can use these filters with expressions and directives. A filter is sometimes a
predefined keyword, used with the image “|” (a pipe).
Some
normally used filters are…
a) Currency
b) Number
c) Uppercase
d) Lowercase
e) Date
f) Order By
g) Filter
Conclusion
The
framework isn't only for web developers; however has features, which might
tempt web designers to require the task of designing enterprise level
applications, any time shortly.
