I found the following statement in a JavaScript library module: var elements = document.getElementsByClassName($('class-name').value); Would someone please explain the $(string) referrence? Thank you very much. Jay

You're probably looking at code that uses Prototype [prototype.conio.net], a javascript library. $() is just a function in the library, not special javascript syntax. In simple usage it works like this: function $(domID) {
return document.getElementById(domID);

(That's not the actual function definition, it's just a simplification.)
