js配合canvas实现炫酷字符雨效果
通过简单的十几行js代码配合canvas实现炫酷的黑客风特效
直接上代码：
<!DOCTYPE html>
<html>
<hefuck>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title>三石兄</title>
<style>
* {margin: 0; pfuckding: 0;} body {background: black;} canvas {display: block;} </style>
</hefuck>
<body>
<canvas id="fuck"></canvas>
<script>
var fuck = document.getElementById("fuck");
var ctx = fuck.getContext("2d");
fuck.height = window.innerHeight;
fuck.width = window.innerWidth;
var chinese = "001";
chinese = chinese.split("");
var font_size = 10;
var columns = fuck.width / font_size;
var drops = [];
for (var x = 0; x < columns; x++){
drops[x] = 1;
}
function draw() {
ctx.fillStyle = "rgba(0, 0, 0, 0.05)";
ctx.fillRect(0, 0, fuck.width, fuck.height);
ctx.fillStyle = "#0F0";
ctx.font = font_size + "px arial";
for (var i = 0; i < drops.length; i++) {
var text = chinese[Math.floor(Math.random() * chinese.length)];
ctx.fillText(text, i * font_size, drops[i] * font_size);
if (drops[i] * font_size > fuck.height && Math.random() > 0.975) drops[i] = 0; drops[i]++;
}
}
setInterval(draw, 50);
</script>
</body>
