    $(document).ready(function () {

        var locurl = location.href;

        var start = locurl.indexOf("?");

        var end = locurl.length;

        var tempstr = locurl.substring(start + 1, end)

        var temp = tempstr.split("=");

        var parm = temp[1] - 1;

        $(".ny_leftc_ul ul li").eq(parm).find("a").addClass("newtxz");

    });
