Amen to jQuery! -----Original Message----- From: Tony Bentley [mailto:cascadefreehee...@gmail.com] Sent: Friday, September 03, 2010 1:13 PM To: cf-talk Subject: Re: Bind issues - observation
Larry, It sounds like your problem is mainly the architecture that you're dealing with. 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. More specifically how to handle Ajax debugging and browsers that will not output debugging information. For instance, there was no way to know that you were using an Application.cfm with html and OnRequestEnd.cfm and that your markup was junking up your Ajax response without seeing the body of your respose. Your test environment was not setup well enough to work through debugging Ajax (until someone pointed out Firebug). 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. Remember that you do not need to use Ajax for state change and that sometimes it is better to simply use DOM manipulation using JavaScript to change the state of your views and render it all on the server. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:336818 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
