## Code implementation:

 <html>
 <head>
     <title>PHP中文网</title>
     <meta charset="utf-8">
     <script src="http://www.jq22.com/jquery/jquery-1.10.2.js"></script>
     <script>
     /*
     11     ① 用setInterval(draw, 33)设定刷新间隔
     12
     13     ② 用String.fromCharCode(1e2+Math.random()*33)随机生成字母
     14
     15     ③ 用ctx.fillStyle=’rgba(0,0,0,.05)’; ctx.fillRect(0,0,width,height); ctx.fillStyle=’#0F0′; 反复生成opacity为0.5的半透明黑色背景
     16
     17     ④ 用x = (index * 10)+10;和yPositions[index] = y + 10;顺序确定显示字母的位置
     18
     19     ⑤ 用fillText(text, x, y); 在指定位置显示一个字母 以上步骤循环进行，就会产生《黑客帝国》的片头效果。
