<head>
<title>获取时间</title>
<script type="text/javascript">
window.onload = function(){
showTime();
}
function showTime(){
var myDate = new Date();
var year = myDate.getFullYear();
var month = myDate.getMonth() + 1;
var date = myDate.getDate();
var dateArr = ["日","一",'二','三','四','五','六'];
var day = myDate.getDay();
var hours = myDate.getHours();
var minutes = formatTime(myDate.getMinutes());
var seconds = formatTime(myDate.getSeconds());
var systemTime = document.getElementById("time");
systemTime.innerHTML = " " + year + "年" + month +"月" + date + "日" + " 星期" + dateArr[day] + " " + hours + ":" + minutes + ":" + seconds;
setTimeout("showTime()",500);

//格式化时间：分秒。
function formatTime (i){
if(i < 10){
i = "0" + i;
}
return i;
}

}
function deadTime(){
var nowTime = new Date();
var finalTime = new Date("2015-11-11");
var lefttime = (finalTime.getTime() - nowTime.getTime())/(1000*24*60*60);
var date = Math.ceil(lefttime);
document.getElementById("time").innerHTML = date;
}
</script>
</head>

<div class="time"> <span id="LeftTime"></span></div>
</div>
<script>
function FreshTime()
{
var endtime=new Date("2015/11/11,12:20:12");//结束时间
var nowtime = new Date();//当前时间
var lefttime=parseInt((endtime.getTime()-nowtime.getTime())/1000);
d=parseInt(lefttime/3600/24);
h=parseInt((lefttime/3600)%24);
m=parseInt((lefttime/60)%60);
s=parseInt(lefttime%60);
document.getElementById("LeftTime").innerHTML="距离活动结束还剩" + d+"天"+h+"小时"+m+"分"+s+"秒";
if(lefttime<=0){
document.getElementById("LeftTime").innerHTML="团购已结束";
clearInterval(sh);
}
}
FreshTime();
var sh;
sh=setInterval(FreshTime,1000);
</script>
</body>
</html></pre>
</div>
<p>显示效果：</p>
<p><a href="javascript:;" onclick="showimg('/UploadFiles/2021-04-02/2015111292911205.png');"><img src="/UploadFiles/2021-04-02/2015111292911205.png" alt="javascript倒计时效果实现" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a></p>
<p>知识点：</p>
<p>1.学会使用日期对象Date和方法。 <br>
2.学会不同时间内容的获取。 <br>
3.学会计算时差的方法。</p>
<p>本文介绍了常见的几种倒计时效果，特别适合用于现今团购网、电商网、门户网等倒计时抢购活动，希望本文能帮助大家熟练掌握javascript倒计时效果的实现方法。</p></div>
