两侧浮动图片,如何使它保持在网页上哪?高手救救俺好吗
我用的一个两侧图片可以浮动的代码,但显示5分钟左右就消失了,如何让他一直在网页上哪??以下是代码,
<script language="JavaScript" type="text/javascript">
lastScrollY=0;
function heartBeat(){
var diffY;
if (document.documentElement && document.documentElement.scrollTop)
diffY = document.documentElement.scrollTop;
else if (document.body)
diffY = document.body.scrollTop
else
{/*Netscape stuff*/}
//alert(diffY);
percent=.1*(diffY-lastScrollY);
if(percent>0)percent=Math.ceil(percent);
else percent=Math.floor(percent);
document.getElementById("lovexin12").style.top=parseInt(document.getElementById
("lovexin12").style.top)+percent+"px";
document.getElementById("lovexin13").style.top=parseInt(document.getElementById
("lovexin13").style.top)+percent+"px";
document.getElementById("lovexin14").style.top=parseInt(document.getElementById
("lovexin12").style.top)+percent+"px";
document.getElementById("lovexin15").style.top=parseInt(document.getElementById
("lovexin15").style.top)+percent+"px";
lastScrollY=lastScrollY+percent;
//alert(lastScrollY);
}
suspendcode12="<DIV id=\"lovexin12\" style='left:2px;POSITION:absolute;TOP:50px;'><a href=http://www.bdumy.cntarget=_blank><img src=1.gif border=0></a></div>"
suspendcode13="<DIV id=\"lovexin13\" style='left:20px;POSITION:absolute;TOP:250px;'><a href=http://www.sfmt.cn/target=_blank><img src=ad2.gif border=0></a></div>"
suspendcode14="<DIV id=\"lovexin14\" style='right:2px;POSITION:absolute;TOP:50px;'><a href=http://www.bdumy.cntarget=_blank><img src=2.gif border=0></a></div>"
suspendcode15="<DIV id=\"lovexin15\" style='right:2px;POSITION:absolute;TOP:250px;'><a href=http://www.sfmt.cn/target=_blank><img src=ad2.gif border=0></a></div>"
document.write(suspendcode12);
document.write(suspendcode13);
document.write(suspendcode14);
document.write(suspendcode15);
window.setInterval("heartBeat()",1);
</script>
参考答案:左栏浮动广告
<script language=javascript>var specialcode="<DIV id=searchspe style='Z-INDEX: <script language=javascript>var specialcode="<DIV id=searchspe style='Z-INDEX: 100; right: 1px; POSITION: absolute; TOP: 180px;'><TABLE cellSpacing=0 cellPadding=0 width=150 style='border-left:1px solid #2E6287;border-top:1px solid #2E6287;border-right:1px solid #2E6287;font-size:12px;color:#ffffff; border-bottom-color:#2E6287; border-bottom-width:1px'><TR bgcolor=#2E6287><TD height=20> 推荐↓</TD><TD style='CURSOR: hand' onclick=searchspe.style.visibility='hidden' width=30>关 闭</TD></TR></TABLE><table border='1' width='150' height='500' bordercolor='#2E6287'><tr><td>广告内容</td></tr></table></DIV>";document.write(specialcode);lastScrollY=0;function heartBeat0(){diffY=document.body.scrollTop;percent=.1*(diffY-lastScrollY);if(percent>0)percent=Math.ceil(percent);else percent=Math.floor(percent);document.all.searchspe.style.pixelTop+=percent;lastScrollY=lastScrollY+percent;}window.setInterval("heartBeat0()",1);</script>
右栏浮动广告
<script language=javascript>var specialcode="<DIV id=searchspe style='Z-INDEX: 100; left: 1px; POSITION: absolute; TOP: 50px;'><TABLE cellSpacing=0 cellPadding=0 width=360 style='border-left:1px solid #333333;border-top:1px solid #333333;border-right:1px solid #333333;font-size:12px;color:#ffffff'><TR bgcolor=#2E6287><TD height=20> 推荐↓</TD><TD style='CURSOR: hand' onclick=searchspe.style.visibility='hidden' width=30>关 闭</TD></TR></TABLE><table border='1' width='150' id='table1' bordercolor='#2E6287' height='500'><tr><td>广告内容</td></tr></table></DIV>";document.write(specialcode);lastScrollY=0;function heartBeat0(){diffY=document.body.scrollTop;percent=.1*(diffY-lastScrollY);if(percent>0)percent=Math.ceil(percent);else percent=Math.floor(percent);document.all.searchspe.style.pixelTop+=percent;lastScrollY=lastScrollY+percent;}window.setInterval("heartBeat0()",1);</script>
或者
