Have you heard about AngularJS ?

  • Angular JS is a javascript framewok which is used to create single page responsive web applications. This uses HTML as the template language and extends HTML syntax to express the application components clearly.

  • Angular JS is used to create structured, testable, maintainable front-end application. It is a MVC framework from Google.

  • It implements two-way data binding, connecting your HTML (views) to your JavaScript objects (models).

    Basic components of Angular JS are


    • Are extended html attributes that mark it as an Angular-JS application


    • Binds application data to html view


    • Are java-script objects


    • Are containers


    • Are substituteble objects that are wired together using dependency Injection

    Learn with us

    • Today in this issue, let us learn how to create a simple Angular JS application.
    • To work with angular you need to download angular-min.js or use the file from CDN. The Google CDN provides access to libraries of Angular JS

    In this example , I have downloaded angular-min.js file and using the same file

    Steps to create an simple Angular JS Application

    • Create a static web application using any Text Editor like sublime2 or an IDE[I am using eclipse].
    • Create a folder called scripts inside web [webcontent in case of eclipse] folder and add the downloaded file to this folder.
    • Create a html file and add the below given code.

      AngularJs 1

      Using Directives
      This directive converts the html page as an Angular JS application.

    • This is the root element of an AngularJS application.
    • It will initialize the application automatically when a web page gets loaded.
    • This directive loads the controller for that page
    • You can add this directive to any html tag. I am adding this to <html> tag

      Angularjs 2

      This directive binds HTML elements to application data. The value of the html element like text field is assigned to application data.

      Angularjs 3

      This directive retrieves the value from the application data and provides to Html view. To get the html view expressions also can be used

      AngularJs 4

      Expression also bind application data to html view. They help to get dynamic values in html.
      The syntax for expressions is {{ }}

      AngularJs 5

      How it works?

      • The HTML document gets loaded into the browser, and gets evaluated. The AngularJS JavaScript file gets loaded and the angular global object is created

      • AngularJS scans the HTML code to look for AngularJS apps . Once found, starts working with the model and views. Your page is now ready.

      • Try doing this and see the output by typing your name. You can do more magic working with Angular applications.

An awareness about Ebola

  • Ebola Virus Disease (EVD)  is a severe, often fatal illness in humans.
  • The virus gets transmitted to people from wild animals and spreads in the human population through human-to-human transmission.
  • The average EVD case fatality rate is around 50%.
  • The first EVD outbreaks occurred in remote villages in Central Africa, near tropical rainforests.
  • Early supportive care with rehydration, symptomatic treatment improves survival.
  • Currently there is no licensed treatment or vaccines proven to neutralise the virus but a range of blood, immunological and drug therapies are under development.

During the release in the article “AngularJS 1.3.0 – superluminal-nudge”, Brian Ford — developer program manager for Google — elaborated on the improvements, saying:

“[AngularJS] 1.3.0 has substantial performance improvements that reduce memory consumption, increase the speed of common DOM operations, and improve overall latency of Angular app.  By popular demand, AngularJS now officially has packages published to npm. You can do npm install angular to get AngularJS 1.3.0. We hope this makes it easier for developers to make use of some of the great tools built around npm for front-end web development “
