為什么用了DIV就調用不出來呢
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>定時器</title>
<script type="text/javascript">
? var attime;
? function clock(){
? ? var time=new Date(); ? ? ? ? ?
? ? attime=time.getHours()+"時"+time.getMinutes()+"分"+time.getSeconds()+"秒";
? ? document.getElementById("clock").value = attime;
? }
? window.setInterval(clock,1000)
</script>
</head>
<body>
<div id="clock" style="widht:400px; height:40px; background:#c33;"></div>
</body>
</html>

value是獲取表單里面value的值，div標簽不是表單，這里可用innerHTML
document.getElementById("clock").innerHTML?=?attime;其他：樣式寬度widht應該為width
