近年來,HTML5技術越來越流行,被廣泛應用于網頁開發和移動應用程序開發中。其中,HTML5愛心代碼源碼是網頁設計中非常受歡迎的一個特效。今天,我們就來分享一下HTML5愛心代碼源碼,并且這個源碼是免費的!
<html> <head> <meta charset="utf-8"> <title>愛心代碼源碼</title> </head> <body> <canvas id="myCanvas"></canvas> <script> window.onload=function(){ var canvas=document.getElementById("myCanvas"); canvas.width=window.innerWidth; canvas.height=window.innerHeight; var ctx=canvas.getContext('2d'); var ball_array=[]; var max_ball_number=40; var count=0; function Ball(){ this.x=Math.floor(Math.random()*(canvas.width-0)+0); this.y=Math.floor(Math.random()*(canvas.height-0)+0); this.r=Math.floor(Math.random()*(50-5)+5); this.color = "rgba(" + Math.round(Math.random() * 255) + "," + Math.round(Math.random() * 255) + "," + Math.round(Math.random() * 255) + ",0.7)"; this.vx=Math.floor(Math.random()*(10-(-10))+(-10)); this.vy=Math.floor(Math.random()*(10-(-10))+(-10)); } Ball.prototype.draw=function(){ ctx.beginPath(); ctx.arc(this.x,this.y,this.r,0,Math.PI*2,false); ctx.fillStyle=this.color; ctx.fill(); }; Ball.prototype.move=function(){ this.x+=this.vx; this.y+=this.vy; if(this.x+this.r>=canvas.width||this.x-this.r<=0){ this.vx=-this.vx*(Math.random()*0.8+0.2); } if(this.y+this.r>=canvas.height||this.y-this.r<=0){ this.vy=-this.vy*(Math.random()*0.8+0.2); } this.vy+=2*Math.random()-1; this.vx+=2*Math.random()-1; }; function createBalls(){ for(var i=0;i以上是HTML5愛心代碼源碼,通過canvas繪制出了多個漂浮的愛心的效果。如果您對HTML5愛心代碼有興趣,可以使用以上免費的代碼進行實踐和個性化的調整。
