JS实现团购商品倒计时功能代码

在做商品限时购买，特别是团购方面，倒计时就派上用场啦，下面介绍一款简单实用的倒计时代码，通过纯JS脚本实现。

 <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];
//倒计时结束OVER
