結果顯示為什么是標準時間格式和時分秒格式交替出現？
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script type="text/javascript">
? var attime;
? function clock(){
? ? var time=new Date();? ? ? ? ??
? ? attime=time.getHours()+":"+time.getMinutes()+":"+time.getSeconds() ;
? ? document.getElementById("clock").value = attime;
? }
?var int=setInterval(clock,2000) ;
</script>
</head>
<body>
<form>
<input type="text" id="clock" size="50"? />
</form>
</body>
</html>
結果顯示，先是顯示：Sat Aug 04 2018 17:27:19 GMT+0800 (中國標準時間)
再顯示：17:27:19

我的代碼：這樣也可以：setInterval("clock()",100);
<!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() + ":" + time.getMinutes() + ":" + time.getSeconds();
? ??
? ? document.getElementById("clock").value = attime;
? }
??
? setInterval("clock()",100);
??
</script>
</head>
<body>
<form>
<input type="text" id="clock" size="50" />
</form>

我的代碼：
<!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;

瀏覽器刷新后重新提交代碼

我把你的代碼粘貼到我本地運行只顯示時分秒格式
