Use this function to queue functions you wish to load on window onload. Very useful when code becomes complex.

function addLoadEvent(func) {
	var oldonload = window.onload;
	if (typeof window.onload != 'function') {
		window.onload = func;
	} else {
		window.onload = function() {
			oldonload();
			func();
		}
	}
}
 
//usage
addLoadEvent(firstFunction);
addLoadEvent(secondFunction);
