We have already discussed “Basics of AngularJS” and “Simple Searching and Sorting“. In this article, we will add Pagination feature also to our previous example. What makes difficult is Sorting result when values are returned from Search and pagination is enabled. Unlike previous post we cannot use standard “OrderBy” filter provided by AngularJs framework, this time we have to create Javascript function inside Controller for Sorting purpose.

Prerequisite Libraries :

  1. UnderscoreJs
  2. Bootstrap CSS
  3. AngularJs

This post used “Custom Service”, so please read this article to understand Dependency Injection in AngularJs.

AngularJs is most accepted MVC framework in Javascript developed by Google. In my point of view, If its developed by Google then there must be something new and unique about this library. It can be used to provide MVC architect to your web application. It has great developers community, so if you are stucked somewhere while using this library, you will have tons of supporters.

So what is so special about this framework, other than its developed by Google ?

  • Unlike Backbone and Ember, You don’t have to spend time on Event Handling (Bind, UnBind Events etc).
  • It Works on principal of Dirty Checking.
  • Automatically fires event if something gets changed.

  • AngularJS performance mainly linked to your computer (Client’s Computer) performance.
  • Ergonomical point of view, an HTML page should not have more than 200 fields. More fields will just distract users.

In this article, I will demonstrate how to use AngularJs framework to create simple application. Continue reading “Getting Started with AngularJs”

Recently, I ran into requirement where I was getting JSON response and needed to render it on my Mobile application. I had two Options, Server side processing and Client side Templating.

  1. <% %> – to execute some code
  2. <%= %> – to print some value in template
  3. <%- %> – to print some values with HTML escaped

Example Source code:
