That's a good point. It would be useful to allow for simply passing an
ID. The way it is currently set up, you must pass the object, e.g.:

var foo = document.getElementById('foo');
if (foo) addObjectEventListener(foo, 'load', funct);

Only images, documents, and the window object have a load event (and
maybe layers). You need to either place the javascript after the input
tag in the markup (a bit ugly), add the function to window.onload, or
use a technique which essentially checks ever x milliseconds whether
the element is part of the DOM yet. Yahoo's lib might do this.
Otherwise take a look at Open JSAN's DOM.ready
(http://openjsan.org/doc/a/au/autarch/DOM/Ready/0.13/lib/DOM/Ready.html)
or domready (http://www.brothercake.com/site/resources/scripts/domready/)
