  Is there audio I am missing?

  You won't see audio on the SlideSix one. You need to follow the link to the recorded URL. I know they heard me, so I hope the audio was recorded. :)

  If you think that $().ready() is too short, $() will really annoy you.

  I think you did a good job covering all the basics of things. Figuring out selectors was one of my biggest hurdles and you explained that and the AJAX functions well. It helped me understand some things better. Plus I made it through the whole thing and I have a short attention span ;)

  Holy cow. I have been banging my head for weeks trying to figure out why my CFC's weren't working. I just removed the onRequest method and my problem is solved.
  
  A little OT, but it just made my day.

  Looks good. I am thinking though maybe show off one of the Plug Ins, maybe jqGrid so the CF people can look at it and compare it to inbuild cfgrid (even if you don't explain the code in the Preso).
  
  I also think an immediate question one would get from this preso would be, using jquery instead of CF8-Ajax stuff. So, maybe you want to add a slide on that. For me, its probably down to how much flexibility you want and whats your data size, for example, 5000 records, jqGrid is faster than cfgrid (very minor difference), but it goes up as I go to 50k records.

  Your voice came out good. As you indicated during the presentation, the microphone icon next to my name was going on and off; but my voice just was not recorded.

  @anthony: Heh, for some reason, $("..") as a selector doesn't seem short, but $().ready() does. ;)
  
  @Kumar: I have a slide on plugins, but I skipped it because I ran out of time.

  The UI stuff is a work in progress. Yet the same could be said of Spry... what it does is nice... but both have room to grow to catch up with EXTJS UI. jQuery UI is getting traction... would like to also see more work done with Spry!

  @JF: Agreed. I actually had a slide on jQuery UI and some demos, but I cut it for time reasons.

  Thanks for doing this for the rest of us. Appreciate your time!

  @Ray
  I meant $() as the document ready function. If you pass a function in as an argument to $ it adds it to the dom ready stack.

  Very nice intro to jQuery, Ray. You covered the bases well and I learned some useful stuff along the way.
  
  I see that you used $("#select1 option:selected").val() to retrieve the value of a select box, but I have always found that $("#select1").val() will return the value of the selected option. Is there a reason to use the "option:selected" selector, like browser compatibility?
  
  Another useful plugin is Throbber (http://plugins.jquery.com/project/throbber) to automatically display and hide those spinning loading animations. Like most things jQuery, it's just too dang simple to implement, makes me feel that I'm not working hard enough :).

  Ray,
  
  Excellent introduction to jQuery! Thank you very much for putting that together, really. The only suggestion I have, since you asked, is that the preamble doesn't need to be so long.
  
  Ummm, you also indicated in the preso that you'd make the demo files available, and I came back just now to see if there was a download link yet, and I don't see it.

  @Nando: You can download the files via the embedded the slideshow. Click the slidesix button.
  
  Thanks for the feedback.

  If anyone else is looking for the sample files, you can find them by clicking the Menu button, bottom left of the embedded SlideSix thingy above > then at the top, click the Download Attachment button.
  
  Thanx again Ray!

  Joel Cox: I used that form based on a jQuery Select cheatsheet I found recently. That's the only reason.
