最近小弟看到这样的一个好东东，就是可以为我们的主页设置出一些可以放大或缩小的文字来，好东东不想独占还是拿出来吧！

代码如下：

<!-- Begin

var speed = 20;

var cycledelay = 1000;

var maxsize = 48;

var x = 0;

var y = 0;

var themessage, size;

var esize = "";

function initArray() {

this.length = initArray.arguments.length;

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

this[i] = initArray.arguments[i];

}

var themessage2 = new initArray(

"免费软件随意传播",

"中国电脑教育报和资源站点",

"网站：xiaoguang99122.myetang.com",

"请多多留意最新版"

);

if(navigator.appName == "Netscape")

document.write('<layer id="wds"></layer><br>');

if (navigator.appVersion.indexOf("MSIE") != -1)

document.write('<span id="wds"></span><br>');

function upwords(){

themessage = themessage2[y];

if (x < maxsize) {

x++;

setTimeout("upwords()",speed);

}

else setTimeout("downwords()",cycledelay);

if(navigator.appName == "Netscape") {

size = "<font point-size='"+x+"pt'>";

document.wds.document.write(size+"<center>"+themessage+"</center>"+esize);

document.wds.document.close();

}

if (navigator.appVersion.indexOf("MSIE") != -1){

wds.innerHTML = "<center>"+themessage+"</center>";

wds.style.fontSize=x+'px'

}

function downwords(){

if (x > 1) {

x--;

setTimeout("downwords()",speed);

}

else {

setTimeout("upwords()",cycledelay);

y++;

if (y > themessage2.length - 1) y = 0;

}
