I have a real soft spot for doing things other people think are hard (or better yet, impossible!); this doesn't mean I always succeed, but it does mean I usually want to accomplish what others think “cannot be done.” While sometimes that means challenges like this goal for 2006, this tendency of mine really plays well in the software development field. For example, I cooked up some web drag-and-drop cross-browser javascript code a few years ago and probably more importantly used it as a relevant and intuitive situation in an application (for selecting and sorting from many different types of options). It involved a lot of conditional logic based on browser testing and so on; I really got my DIV tag on back then.
I came across this cross-browser javascript code for drag and drop from etLux that had me waxing nostalgic over those good old days of javascript mayhem. etLux's effort is solid and, based on my testing, runs great on Windows OS with Netscape 4 (yes, I still have that!), Mozilla, and Internet Explorer.
I can't find my javascript library for this, but now I don't have to thanks to etLux's contribution.
