首次参加csdn的活动“提交一个元旦倒计时代码”，纪念一下。

使用了setInterval函数传递第三个参数，IE9以及以下版本不支持。

<!doctype html>
<html>
<head>
<script type="text/javascript">
var showCountDown = function(dateStr) {
					var toDate,nowDate,toTime,nowTime;
					var diff,ms,seconde,minute,hour,day;
					var str;
					toDate = new Date(dateStr);
					nowDate = new Date();

					toTime = toDate.getTime();
					nowTime = nowDate.getTime();

					diff = toTime - nowTime;

					if(diff > 0) {
						//console.log(diff);
						ms = Math.floor(diff % 1000);
						//console.log('ms: ' + ms);
						diff = diff / 1000;
						second = Math.floor(diff % 60 );
						diff = diff / 60;
						minute = Math.floor(diff % 60);
						diff = diff / 60;
						hour = Math.floor(diff % 24);
						diff = diff / 24;
						day = Math.floor(diff % 24);

						document.getElementById('day').innerHTML = day + "天";
						document.getElementById('hour').innerHTML = hour + "小时";
						document.getElementById('minute').innerHTML = minute + "分钟";
						document.getElementById('second').innerHTML = second + "秒";
	                    
					}
					else {
						alert('倒计时已结束！');
					}

				}

function init() {
	showCountDown("2023-1-1 00:00:00");
	setInterval(showCountDown,1000,"2023-1-1 00:00:00");
}
