This is actually an equivalent loop, just a different way of writing it.

Peter, there is nothing wrong with your loop. I believe it is actually
working properly, but you cannot see this because of how you are trying
to show the results. Try this, just for the heck of it:

var valuestr = '', inputs = document.getElementsByTagName('input');
for (var i=0; i<inputs.length; i++) {
	valuestr += inputs.item(i).value;
}
alert(valuestr);
