function writeSlt(arrstr,arrstrValue,selectedstr)
'arrstr 要顯示在option里面的值，arrstrValue option的實際值，selectedstr要選中的默認值
'將一個字串分割為數組，輸出select的option，并選中selectedstr arrstr&arrstrValue長度要一致
arr=split(arrstr,",")
arrValue=split(arrstrValue,",")

可以從數據庫中讀出數據，形成逗開分隔的字符串，來動態生成select的<option>

function getArrString(table,fld,cond,sortfld)
'獲取一個指定表中指定字段指字條件的數據，返回一個以逗號分隔的字符串
set rs=server.createobject("adodb.recordset")
sql="select " & fld & " from " & table
if len(cond)>0 then
 sql=sql & " where " & cond
end if
if len(sortfld)>0 then
 sql=sql & " order by " & sortfld
end if
rs.Open sql,conn,1,1
if not (rs.bof or rs.EOF) then
 do while not rs.EOF
  getArrString=getArrString & trim(rs(fld)) & ","
  rs.MoveNext
 loop
end if
getArrString=left(getArrString,len(getArrString)-1)
rs.Close
set rs=nothing
end function
