Low Pro – Unobtrusive Scripting for Prototype
Category: Library, Prototype
, Rails
The library adds the following:
- handy DOM navigation functions to elements - ex:
JAVASCRIPT:
-
$('widget').nextElement(); $('converge').replace(element)
-
- a prototype friendly version of DOM Builder
- replaces Event.observe and Event.stopObserving with Dean Edwards addEvent and removeEvent routines.
- Declarative behaviors via Event.addBehavior(), including an OO approach where you create Behavior "classes" which can then be attached to elements.
- Optional usage of Sylvian Zimmer's $$ optimization
All in all it looks like a great add on to prototype - my only wish is that some of this stuff looks like it should be in the main code base, and not a third party add-on!

did you mean to say ‘WITH’ breaking backwards compat????
Thanks Mario, I fixed that.
Some of their methods are covered in the V1.5.0_rc1 of Prototype.
I really like their Event mods and trigger method. The $ shortcuts = pretty cool but that kinda stuff can get out of control.. I have chossen a different approach in making an ‘onReady’. I use Event.observe, but make it handle the Event.observe(‘DOMContentLoaded’,….); just like mozilla/opera 9 do.
DOM navigation convenience methods actually ARE in the main codebase as of yesterday, aren’t they?
it breaks with the JSON library from json.org – the Event.observe code includes some circular reference somewhere which throws json.js into a fit of recursion.
