var ssyear=new Array("子鼠","丑牛","寅虎","卯兔","辰龙","巳蛇","午马","未羊","申猴","酉鸡","戌狗","亥猪");
document.write(year+"年\n"+ssyear[ssc]);
}

}
</SCRIPT>
<FORM name=frm>
出生年份：<INPUT name=inyear size=4 value=1986> <BR><INPUT onclick=getpet() type=button value=看看属什么><INPUT name=birth size=9></FORM>
</body>
</html>
方法三：（大概的计算方法）
（年份+9）%12 = 1 ：鼠
= 2 ：牛
= 3 ：虎
