脚本说明:
第一步:把如下代码加入<head>区域中
<SCRIPT language=javascript><!--
function setVariables() {
if (navigator.appName == "Netscape") {
v=".top=";
dS="document.";
sD="";
y="window.pageYOffset";
}
else {
v=".pixelTop=";
dS="";
sD=".style";
y="document.body.scrollTop";
}
}
function checkLocation() {
object="object1";
yy=eval(y);
eval(dS+object+sD+v+yy);
setTimeout("checkLocation()",10);
}
//-->
</SCRIPT>
第二步:把如下代码加入<body>区域中
<div id="object1" style="position:absolute; visibility:show; left:0px; top:0px; z-index:2">
<table width=128 border=0 cellspacing=20 cellpadding=0>
<tr>
<td height="97">
<a href="dao1.htm" tppabs="http://www.csdn.net/javascript/dao1.htm"><img src="j2.gif" tppabs="http://www.csdn.net/javascript/j2.gif" width="105" height="21" border="0"></a><br>
<a href="dao2.htm" tppabs="http://www.csdn.net/javascript/dao2.htm"><img src="email.gif" tppabs="http://www.csdn.net/javascript/email.gif" width="105" height="21" border="0"></a><br>
<a href="dao3.htm" tppabs="http://www.csdn.net/javascript/dao3.htm"><img src="arrow.gif" tppabs="http://www.csdn.net/javascript/arrow.gif" width="105" height="21" border="0"></a>
</td>
</tr>
</table>
</div>
第三步:把<body>区域改为
<body bgcolor="#fef4d9" OnLoad="setVariables();checkLocation()">
