怎样在网页中插入时间？

网页本来就是由代码组成的，在需要的位置插入下面的代码即可。
<script language="JavaScript">
var enabled = 0; today = new Date();
var day; var date;
if(today.getDay()==0) day = "星期日"
if(today.getDay()==1) day = "星期一"
if(today.getDay()==2) day = "星期二"
if(today.getDay()==3) day = "星期三"
if(today.getDay()==4) day = "星期四"
if(today.getDay()==5) day = "星期五"
if(today.getDay()==6) day = "星期六"
document.fgColor = "000000";
date = "今天是" + (today.getYear()) + "年" + (today.getMonth() + 1 ) + "月" + today.getDate() + "日" + day +"";
document.write(date);
</script>

<script language=JavaScript>
<!-- document.write
now = new Date()
document.write
if (now.getDay() == 5)document.write("星期五")
if (now.
