在网页增加美美的特效



<SCRIPT language=JavaScript>
<!--
var number =12
var speed = 50
var maximg =2
var act = new Array(),positionX = new Array(),positionY = new Array()
var moveX = new Array(),moveY = new Array()
var j = maximg
img = new Array()
img[0] = "1.gif"
img[1] = "2.gif"
img[2] = "3.gif"
for (var i = 0; i < number ;++ i) {
act = 0
positionX = Math.random()*document.body.clientWidth-50
positionY = Math.random()*document.body.clientHeight
moveX = 0.1 + Math.random()/100
moveY = 0.1 + Math.random()*3
if (i == 0)
{
document.write("<div id=\"fly"+ i +"\" style=\"POSITION] + "\" border=\"0\"></div>")}
else {

for (var i = 0; i < number ;++ i) { // iterate for every fly
positionY -= moveY

document.all["fly"+i].style.pixelTop = positionY+ Math.cos(act)*positionY/15
document.all["fly"+i].style.pixelLeft = positionX + Math.sin(act)*positionX/50
if (positionY < 0) {

在 var number =12 中修改图片出现的数量
在 var speed = 50 中修改变换的速度
在 var maximg =2 中修改图片的数量(真实数量-1)
自行修改图片的名称或路径

有看必回~~
感谢大大低分享欧~

这是哪种特效ㄚ 看不出来

就一堆图档在页面上漂的怪特效
