这样写有什么错误,帮忙改一下.

Question

<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>

Answer 1

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>
