关于automation服务器不能创建对象求助

Question

function checkFileExt()
{
 var valid=true;
 var fso = new ActiveXObject("Scripting.FileSystemObject");
 NotAllowExt=["asp","cer","cdx","asa","htw","ida","idq","shtm","shtml","stm","printer","cgi","php","php4","cfm","aspx"];
 $(".fileItem").each(function(){if(this.value!="")
   {if(NotAllowExt.find(fso.GetFile(this.value).Type)) valid=false }});
 
 return valid;
}
function checkFileSize()
{
   var uploadSize=0;
   var fso = new ActiveXObject("Scripting.FileSystemObject");
   $(".fileItem").each(function(){if (this.value!="") uploadSize+=fso.GetFile(this.value).Size;});
   if(uploadSize>1024*1024*1024) return false;
    return true;
}
这是我写的判断上传文件文件名和大小是否合法的程序
测试第二个函数总是报错说automation服务器不能创建对象
其中用了jquery

var fso = new ActiveXObject("Scripting.FileSystemObject");
NotAllowExt=["asp","cer","cdx","asa","htw","ida","idq","shtm","shtml","stm","printer","cgi","php","php4","cfm","aspx"];
$(".fileItem").each(function(){if(this.value!="")
  {if(NotAllowExt.find(fso.GetFile(this.value).Type)) valid=false }});
fso =null;//试一下
return valid;
