$(function () {
        $(".navbar‐btn a").each(function () {
            var hreff = this.href.trim().split("/").splice(3, 4);

            if (hreff.length > 1)
                hreff.splice(0, 1);

            if (hreff[0] == window.location.pathname.split("/").splice(1, 1)[0])
                $(this).parent().addClass("active");
        });
    })
