Yeah, I think your right about that coming from the AJAX library, I’m trying to figure out more advanced javascript lately. Is there a convention about the ‘$’ character being used for variable. Sometimes the stupidest thing can hang you up when your unfamiliar with a language. I thought I used to know javascript pretty well, but now I realize people are taking it a lot farther.
BTW: Your site looks and works really great. What Blog software do you use? (you could email me that part :))

@Adam – Actually, what you are showing there simply makes $get and Sys.UI.DomElement.getElementById call the same function. Correct me if I’m wrong, but I think that is from the ASP.NET AJAX Framework set up by Microsoft. I’m pretty sure that right in the framework, they offer $get as a shortcut for the otherwise long winded call.

So does this explain something that I’ve been seeing recently a lot and don’t understand:
var $get = Sys.UI.DomElement.getElementById = function Sys$UI$DomElement$getElementById(id, element) { ………

Firebug lists $get as a prototype, but I don’t understand what’s going on here.

Wow, this will be great for the next time I need to create a Dog or Pet object! Seriously though, programmers should use more meaningful examples. I only read this blog post because I recently found a String.prototype.trim function that is useful for trimming strings.

Good intro to prototypes. One thing I noticed that might leave the novice developer confused is the call() method. There is no mention of where the method is defined. This might be obvious to the more experienced developers, but the dumbed down explanation would surely help the beginners.

Other than that, great stuff. :)
