马上就要到2022年了，于是用前端语言（HTML+css+JavaScript）写了一个跨年倒计时代码，祝大家在新的一年里：所念的人平安喜乐，所想的事顺心如意！代码： <!doctype html><html><head><meta charset="utf-8"><title>新年快乐</title><style>body{overflow: hidden;margin: 0;}h1{position: fixed;top: 30%;left: 0;width: 100%;text-align: center;transform:translateY(-50%);font-family: 'Love Ya Like A Sister', cursive;font-size: 60px;color: #c70012;padding: 0 20px;}h1 span{position: fixed;left: 0;width: 100%;text-align: center;margin-top:30px;font-size:40px;}</style></head><body><h1 id="h1"></h1><canvas></canvas> <script>var canvas = document.querySelector("canvas"),ctx = canvas.getContext("2d");var ww,wh;function onResize(){ww = canvas.width = window.innerWidth;wh = canvas.height = window.innerHeight;}ctx.strokeStyle = "red";ctx.shadowBlur = 25;ctx.shadowColor = "hsla(0, 100%, 60%,0.5)";var precision = 100;var hearts = [];var mouseMoved = false;function onMove(e){mouseMoved = true;if(e.type === "touchmove"){hearts.push(new Heart(e.touches[0].clientX, e.touches[0].clientY));hearts.push(new Heart(e.touches[0].clientX, e.touches[0].clientY));}else{hearts.push(new Heart(e.clientX, e.clientY));hearts.push(new Heart(e.clientX, e.clientY));}}var Heart = function(x,y){this.x = x Math.random()*ww;this.y = y Math.random()*wh;this.size = Math.random()*2 + 1;this.shadowBlur = Math.random() * 10;this.speedX = (Math.random()+0.2-0.6) * 8;this.speedY = (Math.random()+0.2-0.6) * 8;this.speedSize = Math.random()*0.05 + 0.01;this.opacity = 1;this.vertices = [];for (var i = 0; i < precision; i++) {var step = (i / precision - 0.5) * (Math.PI * 2);var vector = {x : (15 * Math.pow(Math.sin(step), 3)),y : -(13 * Math.cos(step) - 5 * Math.cos(2 * step) - 2 * Math.cos(3 * step) - Math.cos(4 * step))}this.vertices.push(vector);}}Heart.prototype.draw = function(){this.size -= this.speedSize;this.x += this.speedX;this.y += this.speedY;ctx.save();ctx.translate(-1000,this.y);ctx.scale(this.size, this.size);ctx.beginPath();for (var i = 0; i < precision; i++) {var vector = this.vertices[i];ctx.lineTo(vector.x, vector.y);}ctx.globalAlpha = this.size;ctx.shadowBlur = Math.round((3 - this.size) * 10);ctx.shadowColor = "hsla(0, 100%, 60%,0.5)";ctx.shadowOffsetX = this.x + 1000;ctx.globalCompositeOperation = "screen"ctx.closePath();ctx.fill()ctx.restore();};function rer(a){requestAnimationFrame(rer);hearts.push(new Heart())ctx.clearRect(0,0,ww,wh);for (var i = 0; i < hearts.length; i++) {hearts[i].draw();if(hearts[i].size <= 0){hearts.splice(i,1);i--;}}}onResize();window.addEventListener("mousemove", onMove);window.addEventListener("touchmove", onMove);window.addEventListener("resize", onResize);requestAnimationFrame(rer);window.onload=function starttime(){time(h1,'2022,01,01'); // 2022年元旦时间ptimer = setTimeout(starttime,1000); // 添加计时器}function time(obj,futimg){var nowtime = new Date().getTime(); // 现在时间转换为时间戳var futruetime = new Date(futimg).getTime(); // 未来时间转换为时间戳var msec = futruetime-nowtime; // 毫秒未来时间-现在时间var time = (msec/1000); // 毫秒/1000var day = parseInt(time/86400); // 天 24*60*60*1000var hour = parseInt(time/3600)-24*day; // 小时 60*60 总小时数-过去的小时数=现在的小时数var minute = parseInt(time%3600/60); // 分 -(day*24) 以60秒为一整份取余剩下秒数秒数/60 就是分钟数var second = parseInt(time%60); // 以60秒为一整份取余剩下秒数obj.innerHTML="<br>距离2022年还有：<br>"+day+"天"+hour+"小时"+minute+"分"+second+"秒"+"<br><span>愿我所念的人平安喜乐，<br>愿我所想的事顺心如意。<br>May the people I think of be safe and happy, <br>and may the things I think of be all right.</span>"return true;}</script></body></html>倒计时效果：上面只是一个动图，时间会一直倒计时的。另外大家还可以加烟花效果，就是当到了春节零点的时候会进入另一个页面，有烟花和音效，想想就很不错呀！当然，写这种类型的代码也不止前端可以，大家也可以试试其他编程语言呀！另外，对于学习编程或者在工作想升职的小伙伴，如果你想更好的提升你的编程能力帮助你提升水平！笔者这里或许可以帮到你~ 编程学习书籍分享：编程学习视频分享：分享（源码、项目实战视频、项目笔记，基础入门教程）欢迎转行和学习编程的伙伴，利用更多的资料学习成长比自己琢磨更快哦！对于C/C++感兴趣可以小编在后台私信我：【编程交流】一起来学习哦！可以领取一些C/C++的项目学习视频资料哦！已经设置好了关键词自动回复，自动领取就好了！
