js倒计时代码:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><html> <head>  <title>js倒计时代码</title>  <meta name="Generator" content="EditPlus">  <meta name="Author" content="k686绿色软件 http://www.k686.com">  <meta name="Keywords" content="绿色软件">  <meta name="Description" content="绿色软件"> </head> <body> k686绿色软件 - http://www.k686.com<script>function countDown( maxtime,fn ){       var timer = setInterval(function()   {   if(maxtime>=0){    minutes = Math.floor(maxtime/60);    seconds = Math.floor(maxtime%60);    msg = "距离结束还有"+minutes+"分"+seconds+"秒";    fn( msg ); if(maxtime == 5*60) alert('注意，还有5分钟!');    --maxtime;   }    else{   clearInterval( timer );fn("时间到，结束!");  }   }, 1000);}</script><div id="timer1" style="color:red"></div><div id="timer2" style="color:red"></div> <script>countDown( 6,function( msg ){document.getElementById('timer1').innerHTML = msg;});countDown( 6000,function( msg ){document.getElementById('timer2').innerHTML = msg;}) </script> </body></html>

忠心感谢来自56484577Q群的wait提供的代码: http://waitdemos.googlecode.com/svn/trunk/tdemos/countDown.html

此代码的优点在于调用时可不用对功能代码做任何修改.需要显示的地方设定容器id,然后输出一小段代码,一个页面无限制倒计时个数:

countDown( 6,function( msg ){document.getElementById('timer1').innerHTML = msg;});

就可以了.

下面一段代码是来自同一个交流群的大神Vilic优化简写后的代码,在此一并表示感谢:
