Now a days i heard so much about AJAX. I am very much intrested to work with new technologies. We are using javascript in our project . I want to know whether can i migrate all my code in javascript to AJAX easily.What if our client ask to use new technology. Can we move to AJAX easily.What are the prerequisites to use AJAX.
In general, I don't think the customer should be specifying the technology. They should be specifying the behaviour of the Web site or Web product, and letting you choose the best technology to implement it.
If you have an existing site or product, you can retro-fit AJAX techniques one bit at a time. I have done this successfully with my product. As well as genuinely improving the product, this has also ticked the marketing box "my product uses AJAX"; most marketeers would not know or care about the difference between an application using AJAX in places and an application using AJAX throughout.
Where you need dynamic updating or background requests, add some AJAX. If you are currently using pre-AJAX techniques like "invisible IFRAME", then these would be excellent candidates for replacement by AJAX.
Alternatively, you can start from scratch and re-do the whole site or product using AJAX. This should end up with cleaner code, but is a much bigger and riskier undertaking. [ December 19, 2006: Message edited by: Peter Chase ]
