这里有新鲜出炉的Javascript教程，程序狗速度看过来！

JavaScript客户端脚本语言

Javascript 是一种由Netscape的LiveScript发展而来的原型化继承的基于对象的动态类型的区分大小写的客户端脚本语言，主要目的是为了解决服务器端语言，比如Perl，遗留的速度问题，为客户提供更流畅的浏览效果。

JS实现商品倒计时实现代码，需要的朋友可以参考一下

<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
