请帮忙关于javascript错误
<head>
<script language="JavaScript" type="text/JavaScript">
var timeid=nullvar
timerunning=false
function stoptime()
{
if(timerunning)
{ clearTimeout(timeid)
timerunning=false
}
}
function starttime()
{
stoptime()
showtime()
}
function showtime()
{
var now=new Date()
var hours=now.getHours()
var minutes=now.getMinutes()
var seconds=now.getSeconds()
var timevalue= " "+((hours>12)?hours-12:hours)
timevalue+=((minutes<10)?":0":":")+minutes
timevalue+=((seconds<10)?":0":":")+seconds
if(hours>=6&&hours<=12)
{timevalue=timevalue+"上午"}
if(hours>12&&hours<=18)
{ timevalue+=("下午")}
if(hours>18&&<=24)
{timevalue+=("晚上")}
document.clock.face.value=timevalue
timeid=setTimeout("starttime()",1000)
timerunning=true
}
</script>
</head>
<body onLoad="starttime()">
现在时刻是
<form name="clock" on submit="0">
<input type="text" name="face" size=12>
</form>
</body>
错误是<body onLoad="starttime()">缺少对象

两个问题
1、
var timeid=nullvar
timerunning=false
null后面的var接错了，应该换行
2、 if(hours>18&&<=24)
少了个hoursTop

你代码风格差极了。
1，要注意结尾标记；
2，逻辑运算符号两端要留点空格。
3，{}对齐
4，注释Top
