http://user:pass@www.example.com/dir1/dir2/file.php?aaa=111&bbb=222&ccc=333#anchor を解析してクエリーのaaaを取得する。

var result = parseUri("http://user@pass:www.example.com/dir1/dir2/file.php?aaa=111&bbb=222&ccc=333#anchor");

alert(result["queryKey"]["aaa"]);

var result = parseUri("http://user@pass:www.example.com/dir1/dir2/file.php?aaa=111&bbb=222&ccc=333#anchor");
