代码如下：
<script language="JavaScript"> <!-- Begin var date = new Date("January 1, 2003"); var description = "the year 2003"; var now = new Date(); var diff = date.getTime() - now.getTime(); var days = Math.floor(diff / (1000 * 60 * 60 * 24)); document.write("<center><h3>") if (days > 1) { document.write(days+1 + " days until " + description); } else if (days == 1) { document.write("Only two days until " + description); } else if (days == 0) { document.write("Tomorrow is " + description); } else { document.write("It's" + description + "!"); } document.write("</h3></center>"); // End --> </script>
