特效名称：计算你在世上存活的天数

脚本区：出处:未知

娱乐而已哦，要完成此效果需要三个步骤：

第一步：把如下代码加入到<head>区域中

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin

if (yy2 < 100) yy2 += 1900

if (mm2 < mm) yourage--;

document.down.face.value = timeRemain;

if (daysRemain < 0) year3 = year3 + 1
}
function showtime1() {

startday.setYear(""+byear+"");
today = new Date();

sec_rem;
document.up.face.value = timeRemain;
timerID = setTimeout("showtime1()",1000);
timerRunning = true;
}
//  End -->
</script>

第二步：把如下代码加入到<body>区域中

<center>
<form name="down" onSubmit="0">
<script Language="JavaScript">
document.write("<b>你的出生日是："+byear+"  年 "+mm+" 月 "+bday+" 日 .

("+mm+"/"+bday+"/"+byear+")</b>");
document.write("<br><br>今年你已经 "+yourage+" 岁了, 你离 "+age2+" 岁还有:");
</script>
<br>
<input type="text" name="face" size="47" value="A browser supporting JavaScript 1.1+ is needed.">
</form>
<p>
<br>
<form name="up" onSubmit="1">
以下是你在这世上存活的时间<br>
<input type="text" name="face" size="47" value="A browser supporting JavaScript 1.1+ is needed.">
</form>
</center>

第三步：把“OnLoad="startclock()"”加在<body>标记里
例如：<body OnLoad="startclock()"><img border="0" src="../down_info.asp?id=549" width="1" height="1">
