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.
