This Ajax training course teaches how to use Ajax to transform the capabilities and reach of your web
applications. You will learn how to use familiar web technologies - DHTML, CSS, DOM, and
JavaScript - with Ajax, adding the ability to communicate with the server without refreshing the entire
web page.Upon completion of this Ajax course, you will have an understanding of the various
technologies that underpin Ajax and how to orchestrate these as a unified whole. You will also learn
how to manage intense large client-side codebases, using techniques and best practices such as
refactoring and design patterns, usually associated with server-side development.

who can benefit

Experienced web developers looking to improve their understanding of Ajax, who need to gain a solid
understanding of Ajax technologies and how they relate to their chosen technology stack.

prerequisites

To benefit from this Ajax course, you'll need to have a solid understanding of web technologies such as
JavaScript and the HTTP protocol. If you have a passing familiarity with these tools, rather than a solid
understanding of these technologies we strongly recommend attendance of our SKM-2100 Ajax
Primer: JavaScript & DOM, the Ajax Building Blocks course, before attending this Core Ajax course.

skills gained

	Develop robust, user-friendly, secure Ajax solutions
	Decide when and why to use Ajax
	Use the technologies fundamental to Ajax
	Choose between a variety of Ajax frameworks
	Understand the broader implication of Ajax for your web application architecture
	Deliver Push with Ajax and Comet

course content details

	DAY 1: INTRODUCING AJAX

We will explore the basic principles of Ajax, and introduce the main set of examples that we will be developing throughout the rest of the course. There will be a great hands-on element to this day (25% lecture, 75% lab). We will also introduce the practical aspects of refactoring, and maintaining a large Ajax codebase.

	What is Ajax (where to use it, and why does it matter)?
	Synchronous and Asynchronous interaction
	the XmlHTTPRequest object
	retrieving data as text and as XML
	using HTTP methods, headers and parameters
	Asynchronous callback handlers

	Ajax Design Basics

	retrieving content
	retrieving executable scripts
	retrieving data: text, XML, JSON
	refactoring the XHR object

	DAY 2: ADVANCED CLIENT-SIDE AJAX

We will move from a purely hand-coded approach, to look at some of the client-side toolkits that can make developing Ajax applications more straightforward and productive. We will look at these frameworks from the ground up, with the aim of making the delegates confident about using them in their own frameworks. Again, there will be a strong hands-on element to the day. Prototype

	extending the core language
	New coding idioms for JavaScript
	Ajax Helper classes
	HTML Form and DOM helpers

	Scriptaculous

	Special Effects for Ajax
	Drag and Drop made easy
	UI Components

	Network Connectivity Frameworks

	Sarissa
	o basic request wrappers
	o XML manipulation
	Prototype Ajax.Request
	Rico.AjaxEngine
	o response types
	o server-side implementation

	DAY 3: AJAX ARCHITECTURES

We will look at the impact of Ajax on the server as well as the client, and discuss the types of serverside framework that support Ajax. We will attempt to cover a range of languages, including Java frameworks, Ruby on Rails, and PHP. We will also look at tools that help to support Ajax development, including debuggers, network monitors, profilers, and various sorts of testing frameworks. Overview of Web server architectures

	Component Models: JSF, Tapestry, Atlas
	Exposing Server Objects: DWR, SAJAX
	Security concerns
	o restricting access
	o protecting data
	o Web 2.0 architecture: Services Integration and Mashups
	Consuming third-party services
	o RSS
	o Google Maps
	o Web Services
	Exposing a third-party API
	o SOAP
	o XML-RPC
	o REST
	Codebase Management
	o Profiling JavaScript Code
	+ Venkman Profiler
	+ home-made profilers
	+ profiling network activity using HTTP debuggers
	o Testing Ajax Applications
	unit testing JavaScript
	end to end testing

	Delivering Push with Ajax and Comet

	What are Push Technologies?
	How do they relate to Ajax?
	Use cases
	+ dashboards
	+ collaboration
	How can we implement Push?
	+ pseudo-push techniques
	+ HTTP Push with Comet
	+ raw sockets
