js implements countdown and time objects
The JS code to implement the countdown effect is as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>h
<style>
#box {
width: 100%;
height: 400px;
background: black;
color: #fff;
font-size:40px;
line-height:400px;
text-align:center;
}
</style>
<script>
window.onload = function(){
var oBox = document.getElementById('box');
var oDate = new Date();//获取当前时间;
oDate.setFullYear(2016,11,31);//自动进位；
oDate.setHours(0,0,0,0);
function countDown(){
//未来时间戳减去现在时间的时间戳;
var ms = oDate.getTime() - new Date().getTime();
//毫秒转换成秒
var oSec = parseInt(ms/1000);
//秒转换成天
var oDay = parseInt(oSec/86400);
//不到一天剩下的秒数;
oSec%=86400;
//转换成小时
var oHour = parseInt(oSec/3600);
//不到一小时剩下的秒数;
oSec%=3600;
//转换成分钟
var oMin = parseInt(oSec/60);
//不到一分钟剩下的秒数;
oSec%=60;
oBox.innerHTML = '距离2016年12月31日还有:'+oDay+'天'+oHour+'时'+oMin+'分'+oSec+'秒';
}
countDown();
setInterval(countDown,1000);
}
</script>
</head>
<body>
<div id="box">距离2016年12月31日还有:xx天xx时xx分xx秒</div>
</body>
</html>The implementation effect is as follows:
Timestamp: The number of milliseconds since January 1970: oDate.getTime(); //Don’t ask me why it is from January 1970 to the present! Go to Baidu!
Time object:
Get time:
var oDate = new Date(); oYear = oDate.getFullYear(); oMon = oDate.getMonth(); oDay = oDate.getDate(); oHou = oDate.getHours(); oMin = oDate.getMinutes(); oSec = oDate.getSeconds(); oWeek = oDate.getDay();
Set time:
oDate.setFullYear(年,月,日); oDate.setMonth(月); oDate.setDate(日); oDate.setHours(时,分,秒,毫秒); 时间会自动进位;
That’s all, there are still many shortcomings , I hope everyone can provide more valuable opinions! Learn from each other! Learn from each other!
