我最近做了个单项选择题, 不知道怎么判断选中没有.
请大家帮帮忙!急!!!谢谢

你怎么知道用户填写的登录名是什么？

判断是否获取到了值

if request.form(元素名称)="" then
   
   response.write"没有选择!"

end if

我也是那样写的,就是提交的时候不判断啊?我不知道是那错了?

建议先用javascript在前台获得值，然后提交到后台

<table cellpadding="0">
                  <form name="form1" method="post" action="?action=Save" onclik="return aa()"> <tr>
                
                   <td height="21" align="left">一、选择题（共 <%=request("xz")%> 道，每题 <%=request("xzf")%> 分）</td>
      </tr>
                
                         <%
                          set rs=server.CreateObject("adodb.recordset")
                          sql="select top 4 * from car_mnks "
                          rs.open sql,conn,1,2
                          if not rs.eof then
                          do while not rs.eof  
                          %>
                                    
        <tr>  
          <td width="950" height="27" bgcolor="#FFFFCC"><%=rs("xzt")%></td>
                  
        
                              <tr>
                                <td height="29" bgcolor="#F5F2B6">
            <input type="radio" name="<%=rs("id")%>" value="<%=rs("xx_A")%>" /> A.<%=rs("xx_A")%>
  
            <input type="radio" name="<%=rs("id")%>" value="<%=rs("xx_B")%>" /> B.<%=rs("xx_B")%>
 
              
            <input type="radio" name="<%=rs("id")%>" value="<%=rs("xx_C")%>" />C.<%=rs("xx_C")%>
  
            <input type="radio" name="<%=rs("id")%>" value="<%=rs("xx_D")%>" /> D.<%=rs("xx_D")%>              
                            </td>
                              </tr>
                              <%
                                 rs.movenext
                                 loop
                                 end if
                                 rs.close
                                 set rs=nothing
                             %>
                              
                              <tr>

                                <td height="31" align="center">
                            <input type="Submit" name="submit" value="看看我的得分" />
                                <input type="reset" name="reset" value="重新选题"/></td>
      </tr>
      </form>
我的选项按钮是这样折,谁能帮我判断一下怎么就可以选中题了
我是刚学ASP,怎么不会.希望大家帮忙.谢谢各位了!!急!!!

为什么没有人告诉我啊?

action="?action=Save

你这值提交到哪个页面？

da.asp

用javascript去判断。
