Ajax training course

This one-day workshop will introduce attendees to one of the newest and hippest technologies on the web. Through a series of lectures and practical examples you will learn the power of the XMLHttpRequest object, and how it can be used to add advanced interactivity to your website through the principle of progressive enhancement. Using the “Hijax” concept, you will learn how to create applications that are highly flexible that degrade gracefully. Learn how to script your own Ajax solutions rather than relying on a third-party library.

This training course is taught by Clearleft Technical Director, Jeremy Keith. Jeremy is the author of the book Bulletproof Ajax, and a recognised expert on Ajax and the DOM. By the end of this course you’ll have a full understanding of how the XHR object works and how it can be used to transport data between the server and browser without causing a page refresh. You will learn how to add Ajax interactivity to your page in a way that doesn’t break the fundamental concepts of the web, and help improve usability. Through the practical examples demonstrated in this session, you will learn how to create advanced form validation and even an Ajax shopping cart.

This course is a perfect for intermediate developers with a good understanding of CSS and XHTML, and a basic grasp of JavaScript and the DOM.

Private training

The course is ideal for 4-8 people and prices start from £1600+VAT. Sessions can either be run on site at your offices, or at our state-of-the-art training centre in Brighton.
