JS实现商品倒计时实现代码

<SCRIPT LANGUAGE="JavaScript">
    function fresh() {
        var time1 = document.getElementById("timeD").value;
        for (var i = 1; i <= 5; i++) {
            var endtime = new Date(time1);
            var nowtime = new Date();
            var leftsecond = parseInt((endtime.getTime() - nowtime.getTime()) / 1000);
            d = parseInt(leftsecond / 3600 / 24);
            h = parseInt((leftsecond / 3600) % 24);
            m = parseInt((leftsecond / 60) % 60);
            s = parseInt(leftsecond % 60);
            //        document.getElementById("times").innerHTML=__h+"小时"+__m+"分"+__s+"秒";
            document.getElementById("times"+i.toString()).innerHTML = h + "小时" + m + "分" + s + "秒";
            if (leftsecond <= 0) {
                A
            }
        }
    }
    fresh()
    var sh;
    sh = setInterval(fresh, 1000);
</SCRIPT>

           //实现商品倒计时开始
            DataSet dataset = new DataSet();
            string connStr = ConfigurationManager.ConnectionStrings["sqlservercon"].ConnectionString;
            using (SqlConnection conn = new SqlConnection(connStr))
            {
                conn.Open();
                using (SqlCommand cmd = conn.CreateCommand())
                {
                    cmd.CommandText = "Select * from T_buondTimeBuy";
                    SqlDataAdapter adapter = new SqlDataAdapter(cmd);
                    adapter.Fill(dataset);
                }
            }
            DataTable table = dataset.Tables[0];
            for (int i = 0; i < table.Rows.Count; i++)
            {
                DataRow row = table.Rows[i];
                 time[i]= (row["time"]).ToString();
            }
        
            timeD.Value = time[1];
            //实现商品倒计时结束
