It is really important to understand modern Ajax (not the old Async > JavaSript & XML) and how to finely tune Ajax JavaScript libraries to do what > you want.

In my testing environment, I use Firebug in Firefox to debug > EVERY SINGLE REQUEST. If you cannot debug your requests/responses and > view JS errors, there is no way you can build an application that uses Ajax. > Even if Firebug didn't exist, there are ways around it. For instance, before > firebug many developers would just log each! > request and response and view logfiles to see their issues. > > I also use a TON of jQuery because it simplifies the complexity of JSON and > DOM and allows rapid Ajax development and DOM manipulation. ColdFusion > has some nice built in libraries and I have used all of them at one point or > another but for the sake of being able to extend JavaScript as a real > programming language, I now just write scripts in jQuery and have them > interact with ColdFusion components, returning JSON or strings or load a > dynamic CFML page that takes care of all of the server side rendering that > the browser might bark at (imagine using JSON & DOM manipulation to > output 10,000 records in one go). > > The example I gave you in your earlier post gives you an example of both > client and server rendering of a state change.
