下面本篇文章给大家介绍一下JS实现好看的鼠标跟随彩色气泡效果，文中示例代码介绍的非常详细。有一定的参考价值，有需要的朋友可以参考一下，希望对大家有所帮助。

具体代码：

<!DOCTYPE html><html><head><meta charset="utf-8" /><title></title> <style> *{ margin:0;padding:0; } body{overflow:hidden;} #canvas{ background-color:black; /*width:100%; height:100vh;*/ } </style> </head><body> <canvas id="canvas" ></canvas> </body> <script>var canvas = document.querySelector('#canvas');var ctx = canvas.getContext("2d");var starlist = [];function init(){ canvas.width = window.innerWidth; canvas.height = window.innerHeight;}init();window.onresize = init; canvas.addEventListener('mousemove',function(e){ starlist.push(new Star(e.offsetX,e.offsetY)); console.log(starlist)}) function random(min,max){ return Math.floor((max-min)*Math.random()+ min);} function Star(x,y){ this.x = x; this.y = y; this.vx = (Math.random()-0.5)*3; this.vy = (Math.random()-0.5)*3; this.color = 'rgb('+random(0,256)+','+random(0,256)+','+random(0,256)+')'; this.a = 1; console.log(this.color); this.draw();}Star.prototype={ draw:function(){ ctx.beginPath(); ctx.fillStyle = this.color; ctx.globalCompositeOperation='lighter' ctx.globalAlpha= this.a; ctx.arc(this.x,this.y,30,0,Math.PI*2,false); ctx.fill(); this.updata(); }, updata(){ this.x+=this.vx; this.y+=this.vy; this.a*=0.98; }}console.log(new Star(150,200));function render(){ ctx.clearRect(0,0,canvas.width,canvas.height) starlist.forEach((item,i)=>{ item.draw(); if(item.a<0.05){ starlist.splice(i,1); } }) requestAnimationFrame(render);}render(); </script><div style="text-align:center;"></div> </html>
