How to set a navigation hight light dynamic?

There is a javascript solution:

	var url = window.location.pathname + window.location.search;

	url = url.replace(/(\/(p)\/\d+)|(&p=\d+)|(\/(id)\/\d+)|(&id=\d+)|(\/(group)\/\d+)|(&group=\d+)/, "");

	$(".sNav").find("a[href='" + url + "']").parent().addClass("cur");
