我要黑客帝国里的数字流星雨代码，用html或asp写的

htmlstyle type="text/css"

!--

body {

background-color: #000000;

}

--

/style

Body

script language="JavaScript"

!--

if (document.all){

Cols=60;

Cl=20;//Space's are included so real length is 48!

Cs=20;

Ts=20;

Tc='#008800';

Tc1='#00ff00';

MnS=20;

MxS=30;

I=Cs;

Sp=new Array();S=new Array();Y=new Array();

C=new Array();M=new Array();B=new Array();

RC=new Array();E=new Array();Tcc=new Array(0,1);

document.write(" div id='Container' style='position:absolute;top:0;left:-"+Cs+"'");

document.write(" div style='position:relative'");

for(i=0; i Cols; i++){

S[i]=I+=Cs;

document.write(" div id='A' style='position:absolute;top:0;font-family:Arial;font-size:"

网上找的代码，我给你改了下

怎么把黑客帝国的这段代码放在html主页的背后

!--使用position:absolute;z-index:100;--

canvas id="q"/canvas

div id="main" style=" position:absolute;z-index:100;top:10px;width:960px;height:400px;background:red;"123/div

script type="text/javascript" 

var s = window.screen; 

var width = q.width = s.width; 

var height = q.height = s.height; 

var letters = Array(256).join(1).split(''); 

var _div=document.getElementById("main"); 

_div.style.left=(width-960)/2+"px";//给主页面left定位;

var draw = function () { 

q.getContext('2d').fillStyle='rgba(0,0,0,.05)'; 

q.getContext('2d').fillRect(0,0,width,height); 

q.getContext('2d').fillStyle='#0F0'; 

letters.map(function(y_pos, index){ 

text = String.fromCharCode(3e4+Math.random()*33); 

x_pos = index * 10; 

q.getContext('2d').fillText(text, x_pos, y_pos); 

letters[index] = (y_pos  758 + Math.random() * 1e4) ? 0 : y_pos + 10; 

}); 

}; 

setInterval(draw, 33); 

/script 

HTML5模仿黑客帝国文字矩阵特效，怎么样可以确定文字显示

!DOCTYPE html

html

head

title黑客帝国效果/title

/head

body

canvas id="canvas"/canvas

style type="text/css"

body{margin: 0;

padding: 0;

overflow: hidden;}

/style

script type="text/javascript"

var canvas = document.getElementById('canvas');

var ctx = canvas.getContext('2d');

canvas.height = window.innerHeight;

canvas.width = window.innerWidth;

var texts = '0123456789'.split('');

var fontSize = 16;

var columns = canvas.width/fontSize;// 用于计算输出文字时坐标，所以长度即为列数

var drops = [];//初始值

for(var x = 0; x columns; x++){

drops[x] = 1;

}

function draw(){

//让背景逐渐由透明到不透明

ctx.fillStyle = 'rgba(0, 0, 0, 0.05)';

ctx.fillRect(0, 0, canvas.width, canvas.height);//文字颜色

ctx.fillStyle = '#0F0';

ctx.font = fontSize + 'px arial';//逐行输出文字

for(var i = 0; i drops.length; i++){

var text = texts[Math.floor(Math.random()*texts.length)];

ctx.fillText(text, i*fontSize, drops[i]*fontSize);

if(drops[i]*fontSize canvas.height || Math.random() 0.95){

drops[i] = 0;

}

drops[i]++;}}

setInterval(draw, 33);
