I love the idea of creating the non-page-refreshing apps, but, as someone mentioned earlier, even a relatively simple app just start to overflow with code and it becomes difficult to keep up with what is doing what and when.
Someone mentioned earlier, that instead of putting all their js code on the page, they used includes to include only what they needed at a particular time. How are these includes done with js? Is it similar to <cfinclude> with CF? Can you give me a simple example? (I just need to done some research on js includes...) I really need some way to encapsulate my code to make it more manageable. I mentioned remembering in an earlier posts writing BASIC subroutines back in 1980 that worked very well. I say it worked very well, but it was probably more work than what I have now. But it was easy to say GOTO 1540 to launch the subroutine that started at line 1540. Boy, things have gotten complicated today! (But there were not even graphics of any significance back then! It was CompuServe at $6.00 per hour for text-based communications!)

Hang in there on this client-side stuff! It will all continue to become more clear as you work with it. I have some sympathy for what you're going through with it. As more of a front-end guy, it happens to me every time I tackle back-end stuff like databases. Help me! Databases! Why can't it be something simple like closures and asynchronous Ajax calls? ;-) -Mike > From: Rick Faircloth > > Here's a method that I'm using to pass data from an ajax > response to another function: (I'm starting with the > success: section of an ajax call) > > success: function(response) { > if ( response.MESSAGE == 'Success' ) > { populateStoryTable(response); } > > else { alert(Rats!
