javascript頁面動態顯示時間變化範例程式碼
頁面動態顯示時間變化的方法有很多，本文為大家介紹下使用javascript的具體實現，感興趣的朋友不要錯過
代碼如下:
<html>
<head>
<title></title>
<script>
function getDateDemo(){
/*
//聲明時間
var date = new Date();
alert(date);//目前時間
alert(date.toLocaleString());//轉化為本地時間
alert(date.getFullYear());//顯示年份
alert(date.getMonth() + 1);//顯示月份 0-11，需要加1
alert(date.getDate());//顯示一月中的日期
alert(date.getDay());//顯示一周的日期，星期幾
alert(date.getHours());//擷取小時時間
alert(date.getMinutes());//擷取當前分鐘
alert(date.getSeconds());//擷取當前秒數
alert(date.getMilliseconds());//擷取當前的毫秒數
alert(date.getTime());//擷取從1970年1月1日午夜零時，到目前時間的毫秒值
*/
//分別擷取年、月、日、時、分、秒
var myDate = new Date();
var year = myDate.getFullYear();
var month = myDate.getMonth() + 1;
var date = myDate.getDate();
var hours = myDate.getHours();
var minutes = myDate.getMinutes();
var seconds = myDate.getSeconds();
//月份的顯示為兩位元字如09月
if(month < 10 ){
month = "0" + month;
}
if(date < 10 ){
date = "0" + date;
}
//時間拼接
var dateTime = year + "年" + month + "月" + date + "日" + hours + "時" + minutes + "分" + seconds + "秒";
//document.write(dateTime);//列印目前時間
var divNode = document.getElementById("time");
divNode.innerHTML = dateTime;
}
window.setInterval("getDateDemo()",1000);//每隔1秒，調用一次getDateDemo()
</script>
</head>
<body>
<div id="time"></div>
</body>
</html>
