看到有些对联广告加了关闭按钮，但很多是flash的，所以对这个“符合标准的对联广告”进行了修改，也加入了关闭按钮(实际是隐藏，不过效果一样)，关于隐藏层，在论坛里搜索了一下，大致找到以下两个：
onclick=\"lovexin14.style.display = 'none'\"
onclick=\"lovexin12.style.visibility='hidden'\"
想问问前辈们，这两种有什么区别？哪种好一些呢？
还有在点了关闭之后，会返回页面顶端，怎么去掉这种情况呢？

("lovexin12").style.top)+percent+"px"; 
document.getElementById("lovexin14").style.top=parseInt(document.getElementById

("lovexin12").style.top)+percent+"px";

lastScrollY=lastScrollY+percent; 
//alert(lastScrollY); 
} 
suspendcode12="<DIV id=\"lovexin12\" style='left:5px;POSITION:absolute;TOP:120px;'><img border=0 src=http://www.gxlcms.com/logos.gif> 关闭</div>" 
suspendcode14="<DIV id=\"lovexin14\" style='right:5px;POSITION:absolute;TOP:120px;'><img border=0 src=http://www.gxlcms.com/logos.gif> 关闭</div>" 
document.write(suspendcode12); 
document.write(suspendcode14); 
window.setInterval("heartBeat()",1); 
</ script>
