<Script Language ="JavaScript">
var fso;
fso=new ActiveXObject("Scripting.FileSystemObject");
if(fso.FileExists("d:\\page_2.htm"))
<a href="page_2.htm">主页面;
else
<a href="page_3.htm">主页面;
</Script>

好像javascript中没有该对象

[seabell]

<Script Language ="JavaScript">
var fso;
fso=new ActiveXObject("Scripting.FileSystemObject");
if(fso.FileExists("d:\\page_2.htm"))
document.write('<a href="page_2.htm">主页面');
else
document.write('<a href="page_3.htm">主页面');
</Script>

改为以下方法好点，没有提示

<a href="page_3.htm">主页面</a>

<IE_Download ID="oDownload" STYLE="behavior:url(#default#download)" />
<script>
var fName='page_2.html'
function onDownloadDone(downData){top.document.links(0).href=fName}
try{oDownload.startDownload('exists.html',onDownloadDone);}catch(e){alert(e.description)}
</script>
