<script type="text/javascript" src="/Res/Scripts/zepto.js"></script>

<script type="text/javascript">
        function getQueryString(name) {
            var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
            var r = window.location.search.substr(1).match(reg);
            if (r != null) return unescape(r[2]); return null;
        }
        var type = getQueryString("type");

        switch (type) {
            case "check":

                $("#ctl00_ContentPlaceHolder1_tab0").addClass("active");
                break;
            case "used":
                $("#ctl00_ContentPlaceHolder1_tab1").addClass("active");
                break;
            case "expired":
