杭州交通信息网乳胶漆自己能刷吗:求解一段javascript代码
来源：百度文库 编辑：杭州交通信息网 时间：2024/05/01 03:57:54
<script language="JavaScript">
var isMonth = new
Array("1月","2月","3月","4月","5月","6月","7月","8月","9月","10月","11月","12月");
var isDay = new
Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六","星期日");
today = new Date () ;
Year=today.getYear();
Date=today.getDate();
if (document.all)
document.title="今天是: "+Year+"年"+isMonth[today.getMonth()]+Date+"日"+isDay[today.getDay()]
</script〉
这段程序能否请高手详细给我讲解，例如其中为何将document。all作为条件什么意思？还有ismonth和isday后面的[]中的内容就能使其显示正确的月份和星期？请求每步详解，越详细越好

isMonth[]本来就是个存储这月份的数组，而today.getMonth()]返回的是从0-11的值，用today.getMonth()]作为数组下标返回的是传统意义上的月份，
isDay[today.getDay()] 同理，document.all是条件
