24、计算出生日期 代码

24、计算出生日期 代码

脚本说明:

第一步:把如下代码加入<body>区域中:

<SCRIPT LANGUAGE="JavaScript">

//  End -->

</script>

<form name="down" onSubmit="0">

<script Language="JavaScript">

document.write("<b>你出生于"+bmonth+" "+bday+", "+byear+".  ("+mm+"/"+bday+"/"+byear+")</b>");

document.write("<br><br>你已经 "+yourage+" ,离你生日还有.");

</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">

你已经生活了...<br>

<input type="text" name="face" size="47" value="A browser supporting JavaScript 1.1+ is needed.">

</form>

 

 

 

第二步:<body>区域中的内容改为:

<body bgcolor="#fef4d9" OnLoad="startclock()">
