Question

我有要求，从组合框/下拉列表中选择多个（超过一个/两个/三个）选项/值，这些值我需要通过sql查询，你能不能请我最早帮助我。

<table border="0" cellpadding="0" cellspacing="0">
<tr class="f10pt">
<td width=90px><b>Country:</td>
<td><select multiple name="Locale" class="f8pt" style="width:80px;">
<option value="">All Locales</option>
<%
SQLstr="Select country_id,country_text from dbo.country with (NOLOCK) order by       country_id Asc"
DocDBRecords.open SQLstr, DOCDB, adOpenStatic, adLockReadOnly
if not DocDBRecords.bof And not DocDBRecords.eof Then 
  Do While Not DocDBRecords.Eof
    Response.Write "<option value=""" & DocDBRecords("country_id") & """"
    If Len(CountryQuery)>0 Then
      If (CInt(DocDBRecords("country_id"))=CInt(CountryQuery)) Then
        Response.Write " SELECTED"
      End If
    End If
    Response.Write ">" & DocDBRecords("country_text") & "</option>"
    DocDBRecords.movenext
  Loop
End If
DocDBRecords.close
%>
</select>

您有选择多个表单元素。如果您选择多个选项，则选项将以逗号分隔的字符串形式发送。

然后你可以做这样的事情

selectname = Request.Form("yourselectname")
selectarray = split(selectname,",")
For Each item In selectarray
    sql ="Insert into yourtable (yourfield) values('" & item & "')"
    conn.Execute sql
Next

如果要将值传递给选择查询，一个选项是使用VBS替换功能将逗号更改为“或countryid =”，例如

idstring = replace(Request.Form("countryid"),","," or where countryid = ")
sql="Select country_id,country_text from dbo.country where countryid = "& idstring

如果您的表单位于面向公众的网站上，我强烈建议您使用某种正则表达式函数，表单数据在发送到数据库之前必须通过该函数，否则您会对SQL注入攻击持开放态度

将多个Selected下拉列表值/选项传递到使用经典asp的Sql Query中
