try this code:
javascript code:
<script>
    $(function () {
        $.extend({
            scrollToTop: function () {
                var _isScrolling = false;
                $("body").append($("<a />")
                                .addClass("scroll-to-top")
                                .attr({
                                    "href": "#",
                                    "id": "scrollToTop"
                                })
                                .append(
                                $("<i />")
                                    .addClass("glyphicon glyphicon-chevron-up active")
                            ));
                $("#scrollToTop").click(function (e) {
                    e.preventDefault();
                    $("body, html").animate({
scrollTop: 0 }, 500);
                    return false;
                });
                $(window).scroll(function () {
 
                    if (!_isScrolling) {
 
                        _isScrolling = true;
 
                        if ($(window).scrollTop() >
150) {
 
                            $("#scrollToTop").stop(true, true).addClass("visible");
                            _isScrolling = false;
 
                        } else {
 
                            $("#scrollToTop").stop(true, true).removeClass("visible");
                            _isScrolling = false;
 
                        }
