关于网页中 左右边上广告问题---进来看看吧!
高手们,你们好,小弟向大家请教个问题:
在网页中加入左右广告,怎么弄呢?我的做法如下:(可是为什么不行呢?)
1.写一个*.JS 程序 如下:
var delta=0.15
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()
{
if(screen.width<=800)
{
for(var i=0;i<collection.length;i++)
{
collection[i].object.style.display= 'none';
}
return;
}
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);
var followObj_y= (typeof(collection[i].y)=='string'?eval(collection[i].y):collection[i].y);
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;
}
if(followObj.offsetTop!=(document.body.scrollTop+followObj_y)) {
var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta;
dy=(dy>0?1:-1)*Math.ceil(Math.abs(dy));
followObj.style.top=followObj.offsetTop+dy;
}
followObj.style.display= '';
}
}
document.write("<img src='Modules/Counter/Counter.aspx?web=00&refer="+escape(document.referrer)+"&url="+escape(window.location.href)+"' width=0 height=0 border=0 >")
var theFloaters= new floaters();
theFloaters.addItem('followDiv2',6,80,'<a href="Modules/Company/MMC.aspx"><img src="Images/left-ad.gif" border=0></a>');
//theFloaters.addItem('followDiv3',6,180,'<a href="Modules/Company/MMC.aspx"><img src="Images/left-ad.gif" border=0></a>');
theFloaters.play();
2.在要加广告的页中加入如下代码:
<script language="javascript" type="text/javascript" src="js/left-ad.js"></script>
高手们,你们看这样子行不行呢?
为什么我的那个图片就不动呢? 而是停在那,不向下游动,这是为什么呢?
高手们,帮帮我吧!
