JavaScript: This is what I get for not wanting to repeat myself.

add-events.js

/*
 * Example usage:
 * addEvents(document, {
 * 	load: [ foo, bar ],
 * 	click: baz
 * })
 */
function addEvents(obj, list, evt) {
	function isArray(value) {
		return (value instanceof Array)
	}
	// sanity
	if (isArray(list) && !evt)
		alert("addEvents takes an Object, not an Array!")

	// bind all the events in the list as needed
	var keys = evt ? list : Object.keys(list)
	for (i in keys) {
		// we are recursing if evt is present.
		var key = evt ? evt : keys[i]
		var fn = evt ? list[i] : list[key]
		
		// call ourselves while passing the key if we've got an array.
		if (isArray(fn)) {
			addEvents(obj, fn, key)
			continue
		}
		if (obj.addEventListener)
			obj.addEventListener(key, fn, false)
		else if (obj.attachEvent)
			obj.attachEvent("on"+key, fn)
	}
}
