// tired of doing this? :
// var opt = document.getElementById('selBox').options[document.getElementById('selBox').selectedIndex].value;
// try this!
// var opt = document.getElementById('selBox').selectedValue();

HTMLSelectElement.prototype.selectedValue = function() {
	return this.options[this.selectedIndex].value
}

// by the way, if anyone knows how to make this accessible like a property rather than a method
// (ie, without the parens) please let me know :)
