結(jié)果顯示為什么是標(biāo)準(zhǔn)時(shí)間格式和時(shí)分秒格式交替出現(xiàn)？

結(jié)果顯示，先是顯示：Sat Aug 04 2018 17:27:19 GMT+0800 (中國(guó)標(biāo)準(zhǔn)時(shí)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(shí)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);

我把你的代碼粘貼到我本地運(yùn)行只顯示時(shí)分秒格式
