I’ve been fascinated by the asychronous approach to page updates for a long time. At Workflow Designs TopGun classes in the late 90s, similar techniques were taught using a hidden iFrame “backchannel conduit” approach that Steve DeVoll discovered. With the widespread adoption of the XMLHttpRequest object in browsers, and the coining of the AJAX term, these techniques are really becoming prime-time.

I wanted to put together a relatively quick screencast (4:30) to show what people are developing. With AJAX, a picture (or a movie) is worth a thousand words, so watch it and get a quick insight into how these techniques can really change the way you do development.

The following samples are shown in this screencast: [UPDATED with links I forgot]

Future screencasts will show behind the scenes workings of these demos as well as some new demos. I’d also like to do a podcast with some of the people who are publishing these leading edge techniques. I hope you enjoy this screencast, please feel free to give me some feedback on it.

  1. Geez Louise, I just realized that in the many “takes” I did for that screencast, the final version didn’t mention Julian Robichaux, all the early ones did. The code for the View Search that I demo’d is originally based on work from Julian and his Google Suggest style Zip Code lookup:

    In my user group presentations, I ALWAYS list him as the source for this idea. My bad, Julian, sorry.

    I also wasn’t aware until this morning that Julian had also done a Notes version called Notes Suggest at: http://www.nsftools.com/tips/NotesTips.htm#notessuggest.

    Thanks to Richard for pointing it out.

  2. Hi, this is very cool. I like the idea of the screencast.
    Thanks for inspiration and insight.

  3. Great idea presenting this as a “screencast”. If a picture is worth a thousand words then a video has got to be worth more! 🙂

    Anyway, I am in the process of adding the ability to expand/collapse multiple view categories with AJAX in my Domino Web Tools (DWT) project on OpenNTF.org. I should have that posted this weekend and once I do I’ll let you know.
