  <script type="text/javascript">
    function countdown(title,Intime,pId) {
      var online=new Date(Intime); //根据参数定义时间对象
      var now=new Date();   //定义当前系统时间
      var leave=online.getTime()-now.getTime(); //计算时间差
      var day=Math.floor(leave/(1000*60*60*24))+1;
      if (day>1){
          pId.innerHTML="<b>----距离"+title+"还有"+day+"天！<br/>" ; //页面显示信息
      }else{
        if (day==1){
            pId.innerHTML="<b>----明天就是"+title+"啦！<br/>" ; //页面显示信息
        }else{
          if (day==0) {
            pId.innerHTML = "<b>----今天就是" + title + "呀！<br/>"; //页面显示信息
          }else{
              pId.innerHTML="<b>----哎呀!"+title+"已经过了！<br/>" ; //页面显示信息
            }
          }
        }
    }
  </script>
</head>
<body>
  <table width="350" height="450" border="0" align="center" cellspacing="0" cellpadding="0">

              <p id="countDown">
                <b>---</b></p>
                <script type="text/javascript">
                  countdown("2018年中秋节","10/4/2018",countDown); //调用JavaScript函数
                </script>
