做网站需要一个随着屏幕上下滚动的广告条,在网上搜索了一下,有一些比较的适合,下面的代码就是,不过我更需要的是能在某一特定的区域内随屏幕上下滚动的广告条,不知道哪位大大能提供一点帮助?

<script language="JavaScript">
<!--
self.onError=null;
currentX = currentY = 0;
whichIt = null;
lastScrollX = 0; lastScrollY = 0;
NS = (document.layers) ? 1 : 0;
IE = (document.all) ? 1: 0;
<!-- STALKER CODE -->
function heartBeat() {
if(IE) {
diffY = document.body.scrollTop;
diffX = 0;
}
if(NS) { diffY = self.pageYOffset; diffX = self.pageXOffset; }
if(diffY != lastScrollY) {
percent = .1 * (diffY - lastScrollY);
if(percent > 0) percent = Math.ceil(percent);
else percent = Math.floor(percent);
if(IE) document.all.floater.style.pixelTop += percent;
if(NS) document.floater.top += percent;
lastScrollY = lastScrollY + percent;
}
if(diffX != lastScrollX) {
percent = .1 * (diffX - lastScrollX);
if(percent > 0) percent = Math.ceil(percent);
else percent = Math.floor(percent);
if(IE) document.all.floater.style.pixelLeft += percent;
if(NS) document.floater.top += percent;
lastScrollY = lastScrollY + percent;
}
}
if(NS || IE) action = window.setInterval("heartBeat()",1);
