    <body>
        <!-- Middle part -->
        <div class="contScend">

    <script type="text/javascript">

                });
                html += '</ul>';
                $(".contScend").html(html);

                    function() {
                        //After the animation ends, set the current <ul>marginTop to the initial value 0, and then splice the first <li> to the end.
                        $uList.css({
                            marginTop: 0

                    });
            }
        }
    </script>
</html>

test.json

[{
    "name": "Experience Zone Statistics",
    "numb": 0
}, {
    "name": "test909",
    "numb": 0
}, {
