問題描述:

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,

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>

參考答案:

左栏浮动广告

右栏浮动广告

或者

<html>

<head>

</head>

<tr>

页<br>面<br>区<br>域</div></td>

</tr>

</table>

</center>

</div>
