🎇 五种不同的JS烟花特效

🍕 一、简单大气的烟花

演示地址：https://haiyong.site/demo/fireworks1.html

在这里插入图片描述
HTML代码：

这里的HTML代码很简短

<div><canvas id="canvas"></canvas>
</div>

CSS代码

css也只有这两段内容

body{background:black;overflow:hidden;margin:0;
}
canvas{background:#000;
}

JS代码

所有的源码都在这里了，复制粘贴即可

window.addEventListener("resize", resizeCanvas, false);
window.addEventListener("DOMContentLoaded", onLoad, false);
window.requestAnimationFrame = 
window.requestAnimationFrame       || 
window.webkitRequestAnimationFrame || 
window.mozRequestAnimationFrame    || 
window.oRequestAnimationFrame      || 
window.msRequestAnimationFrame     || 
function (callback) {window.setTimeout(callback, 1000/60);
};var canvas, ctx, w, h, particles = [], probability = 0.04,xPoint, yPoint;function onLoad() {canvas = document.getElementById("canvas");ctx = canvas.getContext("2d");resizeCanvas();     window.requestAnimationFrame(updateWorld);} function resizeCanvas() {if (!!canvas) {w = canvas.width = window.innerWidth;h = canvas.height = window.innerHeight;}} function updateWorld() {update();paint();window.requestAnimationFrame(updateWorld);} function update() {if (particles.length < 500 && Math.random() < probability) {createFirework();}var alive = [];for (var i=0; i<particles.length; i++) {if (particles[i].move()) {alive.push(particles[i]);}}particles = alive;} function paint() {ctx.globalCompositeOperation = 'source-over';ctx.fillStyle = "rgba(0,0,0,0.2)";ctx.fillRect(0, 0, w, h);ctx.globalCompositeOperation = 'lighter';for (var i=0; i<particles.length; i++) {particles[i].draw(ctx);}} function createFirework() {xPoint = Math.random()*(w-200)+100;yPoint = Math.random()*(h-200)+100;var nFire = Math.random()*50+100;var c = "rgb("+(~~(Math.random()*200+55))+","+(~~(Math.random()*200+55))+","+(~~(Math.random()*200+55))+")";for (var i=0; i<nFire; i++) {var particle = new Particle();particle.color = c;var vy = Math.sqrt(25-particle.vx*particle.vx);if (Math.abs(particle.vy) > vy) {particle.vy = particle.vy>0 ? vy: -vy;}particles.push(particle);}} function Particle() {this.w = this.h = Math.random()*4+1;  this.x = xPoint-this.w/2;this.y = yPoint-this.h/2;     this.vx = (Math.random()-0.5)*10;this.vy = (Math.random()-0.5)*10;    this.alpha = Math.random()*.5+.5;     this.color;} Particle.prototype = {gravity: 0.05,move: function () {this.x += this.vx;this.vy += this.gravity;this.y += this.vy;this.alpha -= 0.01;if (this.x <= -this.w || this.x >= screen.width ||this.y >= screen.height ||this.alpha <= 0) {return false;}return true;},draw: function (c) {c.save();c.beginPath();         c.translate(this.x+this.w/2, this.y+this.h/2);c.arc(0, 0, this.w, 0, Math.PI*2);c.fillStyle = this.color;c.globalAlpha = this.alpha;         c.closePath();c.fill();c.restore();}}

🍜 二、在农村看到的烟花

演示地址：https://haiyong.site/demo/fireworks2.html（需要使用电脑打开，没做响应式手机端打开一片黑，或者可以看看后面的烟花）
在这里插入图片描述
HTML代码：

这里的HTML代码还是一样的简短

<div id="jsi-fireworks-container" class="container"></div>

CSS代码

css也只有这三段内容

html, body{width: 100%;height: 100%;margin: 0;padding: 0;overflow: hidden;background-color: #101010;
}
.container{position: absolute;width: 500px;height: 500px;top: 50%;left: 50%;margin-top: -250px;margin-left: -250px;
}
canvas{position: absolute;top: 0;left: 0;
}

JS代码

JS代码比较长，我这里放了一部分，需要完整源码的可以关注公众号【海拥】回复【烟花】

};
