这样的东西怎么实现呀？

<SCRIPT LANGUAGE="JavaScript">
<!--
function foo(){
  var $s="";
  for(var $i=1940;$i<=2004;$i++){
       for(var $j=1;$j<=12;$j++){
   $m=($j.toString().length<2)?(0+$j.toString()):$j;
   $s+="<option value=\""+$i+$m+"\">"+$i+"&Auml;ê"+$m+"&Ocirc;&Acirc;"+"</option>";
   }
  }
  document.write($s);
}//-->
</SCRIPT>
<select>
<script>foo();</script>
</select>
