推荐一个不错的浮动广告代码

var imagepath="http://learning.iwebor.com/kry/ad/ad.gif"

var imagewidth=160 //这两行写图片的大小

var imageheight=114

var speed=3;

var imageclick="http://www.iwebor.com/" //这里写点击图片连接到的地址

var hideafter=0

var isie=0;

if(window.navigator.appName=="Microsoft Internet Explorer"&&window.navigator.appVersion.substring(window.navigator.appVersion.indexOf("MSIE")+5,window.navigator.appVersion.indexOf("MSIE")+8)>=5.5) {

isie=1;

}

else {

isie=0;

}

if(isie){

var preloadit=new Image()

preloadit.src=imagepath

}

function pop() {

if(isie) {

x=x+dx;y=y+dy;

oPopup.show(x, y, imagewidth, imageheight);

if(x+imagewidth+5>screen.width) dx=-dx;

if(y+imageheight+5>screen.height) dy=-dy;

if(x<0) dx=-dx;

if(y<0) dy=-dy;

startani=setTimeout("pop();",50);

}

function dismisspopup(){

clearTimeout(startani)

oPopup.hide()

}

function dowhat(){

if (imageclick=="dismiss")

dismisspopup()

else

window.open(imageclick);

}

if(isie) {

var x=0,y=0,dx=speed,dy=speed;

var oPopup = window.createPopup();

var oPopupBody = oPopup.document.body;

oPopupBody.style.cursor="hand"

if (hideafter>0)
