上面的只是一个开始,下面还有很多的,还有它是在<SCRIPT language=JavaScript></SCRIPT>之间,该怎样写啊,完整代码如下:
<SCRIPT language=JavaScript>
var left_img='<a href=http://www. target=_blank><img src=ad/ad1.gif border=0 width=100 height=140></a><br><br><a href="http://www. target=_blank><img src=ad/ad4.gif border=0 width=100 height=140></a>';
//右边
var right_img='<a href=# target=_blank><img src=ad/ad2.gif border=0 width=100 height=140></a><br><br><a href="http://www. target=_blank><img src=ad/ad4.gif border=0 width=100 height=140></a>';
//var right_img='<EMBED src=http://images. quality=high
WIDTH=80 HEIGHT=170 TYPE="application/x-shockwave-flash"></EMBED>';
var delta=0.05
var collection;
function floaters() {
this.items
= [];
this.addItem
= function(id,x,y,content)
{
document.write('<DIV id='+id+' style="Z-INDEX: 10; POSITION: absolute;
width:80px; height:60px;left:'+(typeof(x)=='string'?eval(x):x)+';top:'+(typeof(y)=='string'?eval(y):y)+'">'+content+'</DIV>');
var newItem
= {};
newItem.object
= document.getElementById(id);
newItem.x
= x;
newItem.y
= y;
this.items[this.items.length]
= newItem;
}
this.play
= function()
{
collection
= this.items
setInterval('play()',10);
}
}
function play()
{
for(var i=0;i<collection.length;i++)
{
var followObj
= collection[i].object;
var followObj_x
= (typeof(collection[i].x)=='string'?eval(collection[i].x):collection[i].x);

if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {
var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;
dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));
followObj.style.left=followObj.offsetLeft+dx;
}

}
