這篇文章介紹了頁面實時顯示當前時間的簡單實例有需要的朋友可以參考需要復制代碼代碼如下:

　　
<html>
<head>
<title>JavaScript實現頁面實時顯示當前時間</title>
</head>
<body>
<script language="javascript">
function showtime()
{
var todayhoursecondminuteyearmonthdate;
var strDate ;
today=new Date();
var n_day = todaygetDay();
switch (n_day)
{
case :{
strDate = "星期日"
}break;
case :{
strDate = "星期一"
}break;
case :{
strDate ="星期二"
}break;
case :{
strDate = "星期三"
}break;
case :{
strDate = "星期四"
}break;
case :{
strDate = "星期五"
}break;
case :{
strDate = "星期六"
}break;
case :{
strDate = "星期日"
}break;
}
year = todaygetYear();
month = todaygetMonth()+;
date = todaygetDate();
hour = todaygetHours();
minute =todaygetMinutes();
second = todaygetSeconds();
if(month<) month=""+month;
if(date<) date=""+date;
if(hour<) hour=""+hour;
if(minute<) minute=""+minute;
if(second<) second=""+second;
documentgetElementById(time)innerHTML = year + "年" + month + "月" + date + "日 " + strDate +" " + hour + ":" + minute + ":" + second; //顯示時間
setTimeout("showtime();" ); //設定函數自動執行時間為 ms( s)
}
</script>
<div id="time"></div>
<script language="javascript"> showtime();</script>
</body>
</html>
