Description
|
|
If you have used Google Map, Google Gmail, etc., you must have been amazed
by the fast reponse and the dynamic page refreshing.
What's happening behind the scenes
is a new way of building Web applications that has taken the
Internet by storm. Ajax (Asynchronous JavaScript and XML) capitalizes
on the browser's ability to asynchronously communicate with the web server
and builds on existing JavaScript and XML technologies.
After looking at how Ajax works, this course will cover the techniques,
frameworks, and tools that help build professional Ajax-based Web
applications. More than 70% of the time will be spent on hands-on labs.
