/div 我上面的JS部分的数字全部是用的图片格式显示倒计时数字的哈，你也可以自己改成数字。 好了，上面的代码全部是我之前给客户写的一个春节倒计时贺卡的程序页面，纯原创，并且一直在用，所以是没有任何问题的，你自己应该懂一些技术吧，所以上面的代码你应该看的懂，很简单的。 就不要再追问了，自己多下下功夫研究下，因为最近比较忙，不见得有时间回复，见谅。记得给我分哈，要升级这个号的级别，以后好推广用，谢谢了。
js写在线考试倒计时器
一个html页面，一个按钮，onclick事件
location.href="";
跳转到另一个html页面
另一个页面里
onload = function (){
// 开始计时
}
