var dir = "1"; // Which direction does window come from (0 for top - 1 for left)
var delay = "1"; // How long before window appears (seconds)

var isDOM=document.getElementById?1:0;
var isIE=document.all?1:0;
function showWin(){
if(isDOM) {document.getElementById("popup").style.display="";}

}
function closeWin(){
if(isDOM) {document.getElementById("popup").style.display="none"}
else if(isIE){popup.style.display = "none";}
}

在网页<body>区添加以下代码
<script>
if (navigator.appName=="Microsoft Internet Explorer"){
if (dir == "0"){document.write('<div id="loc" style="position:relative; top:-300" align="center">');}
if (dir == "1"){document.write('<div id="loc" style="position:relative; left:-300">');}

else document.write('<div id="loc" style="position:relative" align="center">');
</script>
<table id="popup" cellSpacing="0" cellPadding="0" border="1" bgcolor="white" style="display:none; border-color:black;" width="300" height="300">

<td align="left" valign="top" bgcolor="blue" width="100%" height="10px">
<font color=white size=2 face=arial><b>

</div>
<script>
function slide(dir){
if (dir == "1" && loc.style.pixelLeft < (screen.width-300)/2){
loc.style.pixelLeft+=5;
move=setTimeout("slide(dir)",50);
}
if (dir == "0" && loc.style.pixelTop < (screen.height-300)/2){
loc.style.pixelTop+=5;
move=setTimeout("slide(dir)",50);
}
}
if (navigator.appName=="Microsoft Internet Explorer") slide(dir);
</script>
修改网页<body>标签，添加OnLoad事件
<body onLoad="setTimeout('showWin()',delay*1000)">
