/*example 1: simple functions*/
function foo(el,el2) {
	alert(el + " " + el2)
}
dom.onload(foo, 'hello','world');



/*example 2: javascript classes with constructor*/
var bar = function () {
	this.id = 'bar';
}

bar.prototype.test =  function (el) {
	alert ( el + this.id );
}

var b = new bar ();

dom.onload(b, b.test, 'welcome to the ');
