实现网页中的浮动广告编程实例

＜script type="text/javascript"＞
var left_img='＜a target=_blank href="连接的地址"＞＜img

src="广告图片" border=0 title=""＞＜/a＞';
//右边
var right_img='＜a target=_blank href="连接的地址"＞＜img

src=广告图片 border=0＞＜/a＞';
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;top:150px;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;
}
