JS倒计时代码(倒計還有多少天)
 

<SCRIPT LANGUAGE="JavaScript"> 
<!-- 
var urodz= new Date("AUG 8,2008"); 
var  s="奥运开幕"; 
var now = new Date(); 
var ile = urodz.getTime() - now.getTime(); 
var dni = Math.floor(ile / (1000 * 60 * 60 * 24)); 
if (dni > 1)    document.write("离"+s+"还有"+dni +"天") 
else if (dni == 1)      document.write("只有2天啦！") 
else if (dni == 0)      document.write("只有1天啦！") 
else     document.write(s+"好象已经过了哦！");
