var parseUri = function (source) {
	var o = parseUri.options,
		value = o.parser[o.strictMode ? "strict" : "loose"].exec(source);

	for (var i = 0, uri = {}; i < 14; i++) {
		uri[o.key[i]] = value[i] || "";
	}

	uri[o.q.name] = {};
	uri[o.key[12]].replace(o.q.parser, function ($0, $1, $2) {
		if ($1) uri[o.q.name][$1] = $2;
	});

	return uri;
};

parseUri.options = {
	strictMode: false,
	key: ["source","protocol","authority","userInfo","user","password","host","port","relative","path","directory","file","query","anchor"],
	q: {
		name: "queryKey",
		parser: /(?=.)&?([^&=]*)=?([^&]*)/g
	},
	parser: {
		strict: /^(?:([^:/?#]+):)?(?://((?:(([^:@]*):?([^:@]*))?@)?([^:/?#]*)(?::(d*))?))?((((?:[^?#/]*/)*)([^?#]*))(?:?([^#]*))?(?:#(.*))?)/,
		loose: /^(?:(?![^:@]+:[^:@/]*@)([^:/?#.]+):)?(?://)?((?:(([^:@]*):?([^:@]*))?@)?([^:/?#]*)(?::(d*))?)(((/(?:[^?#](?![^?#/]*.[^?#/.]+(?:[?#]|$)))*/?)?([^?#/]*))(?:?([^#]*))?(?:#(.*))?)/
	}
};
Használat:
var items = parseUri('http://usr:pwd@www.test.com:81/dir/dir.2/index.htm?q1=0&&test1&test2=value#top');
