运行后只能下拉找到省,省对应的市看不到,我哪里错了?


<tr bgcolor="#FFFFFF">
<td align="right">所在城市：</td>
<td><select size="1" class="wenbenkuang" name="szSheng" onChange=chsel()>
     <option value="xxx" selected>请选择省份……</option>
      <%dim tmpShengid
tmpShengid=0
set rs_s=server.createobject("adodb.recordset")
sql="select * from province  order by shengorder"
rs_s.open sql,conn,1,1
while not rs_s.eof
     if rs("szSheng")=rs_s("ShengNo") then
          tmpproid=rs_s("proid")
%>
<option value="<%=rs_s("ShengNo")%>" selected ><%=trim(rs_s("ShengName"))%></option>
<%
     else
%>
<option value="<%=rs_s("ShengNo")%>" >
<%=trim(rs_s("ShengName"))%></option>
<%
     end if
    rs_s.movenext
wend
rs_s.close
set rs_s=nothing
%>
</select>
<select size="1" class="wenbenkuang" name="szShi">
<%
set rs_s=server.createobject("adodb.recordset")
sql="select * from city where proid="&tmpproid&" order by shiorder"
rs_s.open sql,conn,1,1
while not rs_s.eof
%>
<option value="<%=rs_s("ShiNo")%>" <%if rs("szShi")=rs_s("ShiNo") then%>selected<%end if%>><%=trim(rs_s("ShiName"))%></option>
 <%
    rs_s.movenext
wend
rs_s.close
set rs_s=nothing
%>
                                      </select>
                                </td>
                                </tr>

好像搞晕了,打不开了

省对应的市需要重新提交，原来的程序中应该有提交的语句，你的程序中未见。
就是这个： chsel()函数

我只是把PROVINCE和CITY的数据第一项名字有原来的ID分别改成PROID和CTID,还有CITY的shengid改成proid,就出现问题了
