JavaScript实现前端网页版倒计时
JavaScript实现前端⽹页版倒计时使⽤原⽣JavaScript简单实现倒计时，供⼤家参考，具体内容如下效果代码// An highlighted block<!DOCTYPE html><html><head><meta charset="utf-8"><title></title><!-- css样式 --><style type="text/css">* {margin: 0;padding: 0;}.onsell {height: 400px;width: 200px;border: 1px solid #F2F2F2;margin: 10px;box-shadow: 1px 2px 4px rgba(0, 0, 0, .2);}.box {/* display: none; */float: left;margin: 328px 34px 0;}.box div {position: relative;display: inline-block;width: 40px;height: 40px;background-color: #333;color: #fff;font-size: 20px;text-align: center;line-height: 40px;box-shadow: 1px 2px 4px rgba(0, 0, 0, .4);}</style></head><body><!-- 要求：某商品在将来某⼀天进⾏促销⼀天，利⽤js制作倒计时效果：时：分：秒 --><div class="onsell"><div class="box"><div class="hour">00</div><div class="minutes">00</div><div class="seconds">00</div></div></div></body></html><script>window.onload = function () {let hour = document.querySelector('.hour')let minutes = document.querySelector('.minutes')let seconds = document.querySelector('.seconds')// 倒计时的时间戳使⽤+将时间对象转为时间戳等同于Date.now()let wantTime = +new Date('2021-3-17 18:00:00')countTime()let timer = setInterval(() => {countTime()}, 1000)function countTime() {let currentTime = +new Date()if (wantTime >= currentTime) {let times = (wantTime - currentTime) / 1000 // 总秒数时间戳/1000 = 秒let remainDay = parseInt(times / 60 / 60 / 24) // 余数取整就是剩余的天数console.log(remainDay);if (remainDay === 0) {if(times < 1) {// 倒计时完毕// 这⾥触发操作}// 天数⼩于⼀天开始计时setTime(times)}} else {hour.innerHTML = '00'minutes.innerHTML = '00'seconds.innerHTML = '00'}}function setTime(time) {// 粗糙版let s = parseInt(time % 60)s = s < 10 ?

javascript实现倒计时并弹窗提示特效
javascript实现倒计时并弹窗提⽰特效在前端开发中，难免会⽤到倒计时。
如做的双⼗⼀活动，在距活动开始的半个⽉前需要做些宣传⼯作，需要告知⽤户优惠活动什么时候开始。
这个时候就要⽤到倒计时，如在整站的某个页⾯提醒⽤户活动什么时候开始等。
⽽在活动的后期，特别是在距活动结束仅有1天左右时，就要⽤到弹窗倒计时。
这个倒计时设置在整站的⾸页顶部（当然也可以设置在其它地⽅，如⾸页中部等），并设置弹窗弹出10秒后⾃动消失，由⽤户决定是否点击到相应的活动页⾯，购买产品。
需要的技术⽀持：CSS3，jQuery库；HTML代码如下：<section class="the_body"><div class="countdown"><h3>距中国雄于地球之⽇还有</h3><div class="countdown_time"><span class="the_days"><i>0</i><i>3</i></span><i class="date_text">天</i><span class="the_hours"><i>0</i><i>7</i></span><i class="date_text">时</i><span class="the_minutes"><i>4</i><i>7</i></span><i class="date_text">分</i><span class="the_seconds"><i>1</i><i>1</i></span><i class="date_text">秒</i></div></div></section>css代码如下：.the_body{width: 100%;max-width: 640px;min-width: 320px;margin: 0 auto;}.countdown{background:#ffec20;padding: 10px 0;}.countdown h3{margin:0;padding:5px 0;color:#f53544;text-align:center;font-size:14px;}.countdown .countdown_time{display:block;width:100%;text-align:center;}.countdown .countdown_time i{display:inline-block;position:relative;padding:0 3px;font-style:normal;background:#fff;margin:0 2px;border-radius:3px;box-shadow:0px 1px 1px #ccc;border-bottom:1px solid #cfcfcf;font-weight:bold;}.countdown .countdown_time i:after{content:"";width:100%;border:1px solid #cfcfcf;border-width:1px 0 0;position:absolute;bottom:1px;left:0;}.countdown .countdown_time i:before{content:"";width:100%;border:1px solid #cfcfcf;border-width:1px 0 0;position:absolute;bottom:3px;left:0;}.countdown .countdown_time .date_text{background:transparent;font-weight:bold;box-shadow:none;border-bottom:none;text-decoration:none;padding: 0;}.countdown .countdown_time .date_text:after{content:"";border:none;}.countdown .countdown_time .date_text:before{content:"";border:none;}JavaScript代码如下：<script>function remaintime() {var date = new Date("Jan 1,2015 00:00:00");//设置倒计时结束时间var nowdate = new Date();//获取当前⽇期var remaintime = date.getTime() - nowdate.getTime();//获取现在到倒计时结束时间的毫秒数var remainday = Math.floor(remaintime / (1000 * 60 * 60 * 24));//计算求得剩余天数var remainhour = Math.floor((remaintime - remainday * 1000 * 60* 60 * 24)/ (1000 * 60 * 60));//计算求得剩余⼩时数var remainminute = Math.floor((remaintime - remainday * 1000 * 60* 60 * 24 - remainhour * 1000 * 60 * 60)/ (1000 * 60));//计算求得剩余分钟数var remainsecond = Math.floor((remaintime - remainday * 1000 * 60 * 60 * 24- remainhour * 1000 * 60 * 60 - remainminute *1000 * 60) / (1000));//计算求得剩余秒数//当剩余天数⼩于10时，就在其前加⼀个0，以下剩余⼩时数、分钟数与秒数与此相同if (remainday < 10) {remainday = "0" + remainday;}else{remainday+="";//当剩余天数⼤于10时，剩余天数为数值，这是需要将该值转换为字符串，以下的剩余⼩时数、分钟数与秒数与此相同}if (remainhour < 10) {remainhour = "0" + remainhour;}else{remainhour+="";}if (remainminute < 10) {remainminute = "0" + remainminute;}else{remainminute+="";}if (remainsecond < 10) {remainsecond = "0" + remainsecond;}else{remainsecond+="";}$(".the_days i:first-child").html(remainday.substr(0, 1));$(".the_days i:last-child").html(remainday.substr(1, 2));$(".the_hours i:first-child").html(remainhour.substr(0, 1));$(".the_hours i:last-child").html(remainhour.substr(1, 2));$(".the_minutes i:first-child").html(remainminute.substr(0, 1));$(".the_minutes i:last-child").html(remainminute.substr(1, 2));$(".the_seconds i:first-child").html(remainsecond.substr(0, 1));$(".the_seconds i:last-child").html(remainsecond.substr(1, 2));setTimeout("remaintime()",1000);//设置1秒后调⽤remaintime函数}remaintime();setTimeout(function(){$(".countdown").hide();},10000);//在⾸页设置的弹窗效果，在分页这段代码可以不设置</script>这是我⾃⼰写的倒计时效果，当然每个⼈都可以根据⾃⼰的爱好，设置倒计时的效果。

js获取当前指定的前几天的日期（如当前时间的前七天的日期），倒计时
js获取当前指定的前⼏天的⽇期（如当前时间的前七天的⽇期），倒计时⼀、js获取当前时间。
格式为2016-03-23.var d = new Date(),mon = parseInt(d.getMonth()+1),str = "";if(mon<10){str = d.getFullYear()+"-0"+(d.getMonth()+1)+"-"+d.getDate();}else{str = d.getFullYear()+"-"+(d.getMonth()+1)+"-"+d.getDate();}console.log(str)获取当前时间，特定时间前的⽇期//⽇期时间计算function getBeforeDate(n) {var n = n;var d = new Date();var year = d.getFullYear();var mon = d.getMonth() + 1;var day = d.getDate();if(day <= n) {if(mon > 1) {mon = mon - 1;} else {year = year - 1;mon = 12;}}d.setDate(d.getDate() - n);year = d.getFullYear();mon = d.getMonth() + 1;day = d.getDate();s = year + "-" + (mon < 10 ?

js倒计时的2种方法
js倒计时的2种⽅法第⼀种，简单时长倒计时data() {return {timer: null,m: 0,s: 0,time: null,}},created() {this.resetTime(125); //倒计时125S，根据⾃⼰的时长确定},methods: {//单纯分钟和秒倒计时resetTime(time){this.m = Math.floor(time / 60);this.m = this.m < 10 ? `0${this.m}` : this.m;console.log('this.m--',this.m);this.s = Math.floor(time % 60);this.timer = setInterval(this.countDown,1000);},countDown(){this.s--;this.s < 10 && (this.s = '0' + this.s);// this.s = this.s < 10 ? `0${this.s}` : this.s;if(this.s.length >= 3){this.s = 59;this.m = `0${(Number(this.m)-1)}`;}if(this.m.length >= 3){this.m='00';this.s='00';clearInterval(this.timer);}this.time = `${this.m}分钟${this.s}秒`;console.log(this.m+"分钟"+this.s+"秒");},}第⼆种，根据后端返回的时间戳，与当前时间进去⽐较，进⾏倒计时data() {return { timer: null,time: null,}},created() {this.timer = setInterval(this.countTime,1000);},methods: {countTime() {//获取当前时间let date = new Date();let now = date.getTime();//设置截⽌时间let str="2021/3/15 00:00:00";let endDate = new Date(str);let end = endDate.getTime();//时间差let leftTime = end - now;//定义变量 d,h,m,s保存倒计时的时间let d,h,m,s;if (leftTime >= 0) {d = Math.floor(leftTime/1000/60/60/24);h = Math.floor(leftTime/1000/60/60%24);m = Math.floor(leftTime/1000/60%60);s = Math.floor(leftTime/1000%60);}else { clearInterval(this.timer); //为负数时清掉定时器 }//递归每秒调⽤countTime⽅法，显⽰动态时间效果this.time = `${m}分${s}秒`; if(m == 0 && s == 0) { clearInterval(this.timer); //时间倒计完清掉计时器，并且跳转，这⾥根据⾃⼰的需求写就好了 this.$app.$redirect('/register/invallid',true); }},}。

JS实现倒计时功能（天，时，分，秒）,以及当天倒计时
JS实现倒计时功能（天，时，分，秒）,以及当天倒计时1.给定任意⼀个时间，然后实现现在到那个时间的倒计时。
下⾯的例⼦是显⽰现在到2021年1⽉1号0时0分的倒计时：function showTime() {//获取⽬的⽇期var myyear = 2021; //年var mymonth = 12 - 1; //⽉只需要填写 - 前⾯的数字，这⾥是⼗⼆⽉var myday = 0; //天var myhour = 00; //时var myminute = 00; //分var mysecond = 00; //秒//以上综合填⼊的时间是 2021年12⽉1号0时0分;var time = Number(new Date(myyear, mymonth, myday, myhour, myminute, mysecond));// var time=new Date(myyear,mymonth,myday,myhour,myminute,mysecond).getTime();//获取当前时间var nowTime = Date.now();// var nowTime = new Date().getTime();//获取时间差var timediff = Math.round((time - nowTime) / 1000);//获取还剩多少天var day = parseInt(timediff / 3600 / 24);//获取还剩多少⼩时var hour = parseInt(timediff / 3600 % 24);//获取还剩多少分钟var minute = parseInt(timediff / 60 % 60);//获取还剩多少秒var second = timediff % 60;//输出还剩多少时间console.log(timerFilter(day)+"天"+timerFilter(hour)+"时"+timerFilter(minute)+"分"+timerFilter(second)+"秒")setTimeout(showTime, 1000);//给⼩于10的数值前⾯加 0function timerFilter(params) {if (params - 0 < 10) {return '0' + params} else {return params}}}2.当前时间到当天23:59:59倒计时。
