第一種類:正確に秒までのjavascriptカウントダウンコード
HTMLコード:

<br> function showtime() {
<br> Today = new Date();

第三种：小时倒计时
HTML代码:

第四种：最简倒计时
HTML代码:
<br> <!-- Begin
<br> var timedate= new Date("January 14,2006");
<br> var times=" ";
<br> var now = new Date();
<br> var date = timedate.getTime() - now.getTime();
<br> var time = Math.floor(date / (1000 * 60 * 60 * 24));
<br> if (time >= 0) ;
<br> document.write("<li><font color=#DEDBDE> 2006 "+times+" : <font color=#ffffff><b>"+time +"</b></font> </font></li>");
<br> // End -->
<br>
HTMLコード:
<br> function djs(){
<br> var urodz= new Date("11/12/2008");
<br> var now = new Date();
<br> var num
<br> var ile = urodz.getTime() - now.getTime();
<br> var dni = Math.floor(ile / (1000 * 60 * 60 * 24));
<br> if (dni >1)
<br> num=dni+1
<br> else if (dni == 1) num=2
<br> else if (dni == 0) num=1
<br> else num=0
<br> document.write(num)

今回はシステム時間を使ってカウントダウンをチェックします.手作業で校正する必要がないので、カウントダウンがより正確になります.コードと詳細な注釈は以下の通りです.
