原生js实现2020年元旦倒计时特效

js代码

<script type=\"text/javascript\">
function getRTime() {
	var EndTime = new Date(\"2020/01/01 00:00:00\"); //截止时间
	var NowTime = new Date();
	var t = EndTime.getTime() - NowTime.getTime();
	var d = Math.floor(t / 1000 / 60 / 60 / 24);
	var h = Math.floor(t / 1000 / 60 / 60 % 24);
	var m = Math.floor(t / 1000 / 60 % 60);
	var s = Math.floor(t / 1000 % 60);

	document.getElementById(\"t_d\").innerHTML = d + \" 天\";
	document.getElementById(\"t_h\").innerHTML = h + \" 时\";
	document.getElementById(\"t_m\").innerHTML = m + \" 分\";
	document.getElementById(\"t_s\").innerHTML = s + \" 秒\";
}
setInterval(getRTime, 1000);
</script>
