Advance AngularJs training in Kolkata

Ogma Techlab has been immensely successful in converting it’s students to professionals and masters in the particular respective fields they chose from our lost list of IT courses. In this article let us discuss Angular Js below here:-AngularJs is a Javascript open-source front-end framework that is mainly used to develop single-page web applications(SPAs). It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML. It’s features like dynamic binding and dependency injection eliminates the need for code that we have to write otherwise.AngularJs is rapidly growing and because of this reason, we have different versions of AngularJs with the latest stable being 1.7.7. It is also important to note that Angular is different from AngularJs. It is an open-source project which can be freely used and changed by anyone. It extends HTML attributes with Directives, and data is bonded with HTML. Why use it?

Easy to work with: All you need to know to work with AngularJs is the basics of HTML, CSS, and Javascript, not necessary to be an expert in these technologies.

Time-saving: AngularJs allows us to work with components and hence we can use them again which saves time and unnecessary code.

Ready to use the template: AngularJs is mainly plain HTML, and it mainly makes use of the plain HTML template and passes it to the DOM and then the AngularJS compiler. It traverses the templates and then they are ready to use.

Key Features:

Model View Controller(MVC): An architecture that is a software pattern used to develop an application. It consists of three components in general, they are:

Model: used to manage the application data.
View: responsible for displaying the application data.
Controller: the main job is to connect the model and the view component.

Normally when we talk about MVC architecture, we have to split our applications into these three components and then write the code to connect them. However, in AngularJs all we have to do is split the application into MVC and it does the rest by itself. It saves a lot of time and allows to finish the job with less code.

Data Binding in AngularJS is a two-way process,i.e the view layer of the MVC architecture is an exact copy of the model layer. You don’t need to write special code to bind data to the HTML controls. Normally in other MVC architectures, we have to continuously update the view layer and the model layer to remain in sync with one another. In AngularJs it can be said that the model layer and the view layer remain synchronized with each other. Like when the data in the model changes, then the view layer reflects the change and vice versa. It happens immediately and automatically which helps in making sure that the model and the view are updated all times.AngularJS | ng-js Directive

The ng-Jq directive allows forcing the library used by the angular.element library. The forcing of SQLite should happen when we leave ng-jr blank, otherwise set the name of the jquery variable under the window (e.g., jQuery). SQLite is directly built into AngularJS and is an important subset of jQuery. By default, AngularJS use SQLite. This directive is looked upon by the AngularJS when it needs to get loaded, and it does not wait for the DOMContentLoaded event at all. It should get placed on the element which comes up before going the script which is responsible for leading the angular. Aside from the ng-app directive, if you add ng-jr directive, you can specify the jQuery name which will be available under the window, which is going to be extremely crucial when you are going to use the jQuery with an alias variable.

Note: Only the first instance of the ng-jr directive is going to be used by the AngularJS, while all the others will get ignored. Use jQuery to load the jQuery library before loading the AngularJS then angular will skip SQLite and it will start to use the jQuery library.AngularJS | ng-cut Directive The ng-cut Directive in AngularJS is used to specify the custom behavior functions when the text in input fields is cut. It can be used when we want to call a function that will be triggered when the text is cut from the input field. It is supported by all input elements.
