求教一个关于表单提交的问题

下面是程序代码，提交后出错信息是：对象不支持此属性或方法，没有办法成功提交！
<script langue=javascript>
function edit(){
document.editform.action="link_edit.asp?edit=edit";
document.editform.submit();
}
function del(){
if (confirm("您确定要删除吗？"))
{
        document.editform.action="link_edit.asp?edit=del";
        document.editform.submit();
        }
}
</script>

          <form action="" method="post" name="editform">
          <table width="100%"  border="0" cellspacing="0" cellpadding="0">
                <tr>
                <td width="11%"><input name="listno" type="text" size="6" value="<%=rs("listno")%>"></td>
                <td width="29%"><input type="text" name="webname" value="<%=rs("webname")%>"></td>
                <td width="23%"><input name="linkt" type="text" size="30" value="<%=rs("linkt")%>"></td>
                <td width="25%"><input name="linki" type="text" size="36" value="<%=rs("linki")%>"></td>
                      <input name="keyno" type="hidden" value="<%=rs("keyno")%>">
                <td width="7%"><div align="center"><input type="button" name="Submit1" value="修改" onClick="edit();"></div></td>
                <td width="5%"><input type="button" name="Submit2" value="删除" onClick="del();">
                </tr>
               </table>
               </form>
