JS 缺少对象。

JScript code

lastScrollY=0;function heartBeat(){ var diffY;if (document.documentElement && document.documentElement.scrollTop)diffY = document.documentElement.scrollTop;else if (document.body)diffY = document.body.scrollTopelse{/*Netscape stuff*/}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("lovexin14").style.top=parseInt(document.getElementById("lovexin14").style.top)+percent+"px";lastScrollY=lastScrollY+percent; }window.setInterval("heartBeat()",1);

前台

HTML code

 <script src="/js/dui.js" type="text/javascript"></script>    <div id="lovexin12" style='left: 5px; position: absolute; top: 20px; display: none'>    </div>    <div id="lovexin14" style='right: 5px; position: absolute; top: 20px;'>    </div>

IE8提示行1字符1缺少对象。




[解决办法]
<script src="/js/dui.js" type="text/javascript"></script>放在页面后面或者

window.onload=function()
{
window.setInterval("heartBeat()",1);
}

另外，确保/js/dui.js路径正确
