Our own Michael Mahemoff has been at it again, and this time with a real twist.
Michael has packaged
Bitjuice, a Javascript API that lets you draw graphics by creating complex HTML tables that are styled. Yup, not Canvas, not SVG, but HTML tables!
You can take it for a spin with the
interactive scratchpad.
Marijn Haverbeke has not only been able to
create a syntax-highlighting JavaScript editor in JavaScript, but he has written up
the story of the brutal odyssey to the dark side of the DOM tree.
The story is a great romp through the never-never-land of JavaScript, DOM, and browser “quirks”. It is well worth a read to find out about fun with selection, designMode, parsing, and much much more.
A huge kudos to Marijn.

Fabio Zendhi Nagao, an applied math student and term Moootols fan, has created
fValidator an open source unobtrusive javascript tool for easy handling form validation.
You markup your form something like this:
HTML:
-
-
<input id="exA_Phone" class="fValidate['required','phone']" name="phone" type="text" />
-
And, the framework takes care of the validation. The
example will let you see it at work.
Good stuff. My only complaints are that:
- You should have a way to know the conditions before you try (e.g. required or not)
- If there are more than one validation on a field it looks verbose (has to be a phone AND required)
Christos Constandinou has created
Event.observeMethod, a library that gives you a way of adding event listeners to methods in an object and running other methods before, around and/ or after the method you are listening to.
The code itself is small, based on Prototype, and only 49 lines (1.8kb), uncompressed.
JAVASCRIPT:
-
-
Event.observeMethod( window, 'myNewFunc', myBeforeFunc, Event.BEFORE );
-
Event.observeMethod( Friend, "initialize", this.addBirthday.bind( this ) );
-
Dojo has allowed you to do this kind of thing in its connect() model. You tend to wonder how often people need this granularity versus just being able to attach normal events.
It makes a lot of sense in large scale applications, but maybe not your JS hacking?
Todd Fisher has created
Chat Infection, a simple chat widget that sits on top of Prototype.
You can see Todd's work via
core.js, which is worth looking at to see the
Event.onDOMReady(..) and the like.
Here is a new room:
