Yeah Ben...I think that is a very important distinction for those that may be just strating with AJAX. AJAX is quite simple in the grand scheme of things. What can get complicated is call back functions (or functions to call when the AJAX request is fired) that run when the AJAX response is received. These are what all the various libraries are about (at least that's what I assume as wwe have essentiually rolled our own on top of CFAJAX). These libraries contain functions to allow you to manipulate what is returned and do things like: -change the innerHTML of a DIV (i.e. show an error message without reloading the page) -show a "retriving results" message when the AJAX request fires -closing the same box whenm the results come back -re-populate a related select box -highlight form fields that conyain errors -create drag & drop interfaces These are just simple examples baseda round standard web app interface bits.....it really ends where your imagination does. That's why we are seeing interfaces we haven't seen before in web apps. my 2 cents Cheers Bryan Stevenson B.Comm.
