If you want to you can always prepare and return a json object as a part of the X-JSON header of your server-side script. Then, your onSuccess (or whatever) handler will get two parameters: the XHR object and a JSON object which is the one that's created on the server. That way, on the client side, you'll still just be working with a JSON object which you can use to fill the different portions of your page as necessary.
I'm not sure how you can set a page header in ColdFusion, so if that isn't something that you know how to do or if ColdFusion doesn't really do it, you can always just return the JSON object as a string and then eval() it on the client-side taking appropriate precautions when using the eval() function. -- Dash -- ScottW wrote: > Hey gang - > > Yay, second day with Prototype. :D > > I finished up some other functions that I had initially built using > mxAjax (ColdFusion-oriented bit) this morning, and started tackling > the most involved mxAjax bit I'd done in this pile. > > I have a page that, upon load, lists out a row of info for each group > of DB records it finds.
