为什么用了DIV就调用不出来呢
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>定时器</title>
<script type="text/javascript">
var attime;
function clock(){
var time=new Date();
attime=time.getHours()+"时"+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>
