function writeSlt(arrstr,arrstrValue,selectedstr)
\'arrstr 要显示在option里面的值，arrstrValue option的实际值，selectedstr要选中的默认值
\'将一个字串分割为数组，输出select的option，并选中selectedstr arrstr&arrstrValue长度要一致
arr=split(arrstr,",")
arrValue=split(arrstrValue,",")
j=0
do while j<=ubound(arr)
if trim(arrValue(j))=trim(selectedstr) then
response.write "<option value=\'" & arrValue(j) & "\' selected>" & arr(j) & "</option>"
else
response.write "<option value=\'" & arrValue(j) & "\'>" & arr(j) & "</option>"
end if
j=j+1
loop
end function



可以从数据库中读出数据，形成逗开分隔的字符串，来动态生成select的<option>

function getArrString(table,fld,cond,sortfld)
\'获取一个指定表中指定字段指字条件的数据，返回一个以逗号分隔的字符串
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
