Jquery 获取CheckBoxList 中选择的值和获取RadioButton 选中的状态

    
<tr>
                <td class="td_text" style=" 150px;">
                    工程承包内容：
                </td>
                <td colspan="3" style=" 600px;">
                    <asp:CheckBoxList ID="chkGcnr" runat="server" Height="20px" class="{required:true,messages:{required:'请选择工程承包内容!'}}" Width="550px" RepeatDirection="Horizontal">
                        <asp:ListItem Value="ytgckc" ClassAtt="tab_zbb_htdj_kc.gcnr_ytgckc">岩土工程勘察</asp:ListItem>
                        <asp:ListItem Value="ytgcsj" ClassAtt="tab_zbb_htdj_kc.gcnr_ytgcsj">岩土工程设计</asp:ListItem>
                        <asp:ListItem Value="ytgccs" ClassAtt="tab_zbb_htdj_kc.gcnr_ytgccs">岩土工程测试、监测、检测
                        </asp:ListItem>
                        <asp:ListItem Value="ytgczx" ClassAtt="tab_zbb_htdj_kc.gcnr_ytgczx">岩土工程咨询、监理</asp:ListItem>
                        <asp:ListItem Value="swdzkc" ClassAtt="tab_zbb_htdj_kc.gcnr_swdzkc">水文地质勘察</asp:ListItem>
                        <asp:ListItem Value="gccl" ClassAtt="tab_zbb_htdj_kc.gcnr_gccl">工程测量
                        </asp:ListItem>
                        <asp:ListItem Value="ytgczl" ClassAtt="tab_zbb_htdj_kc.gcnr_ytgczl">岩土工程治理
                        </asp:ListItem>
                        <asp:ListItem Value="gczt" ClassAtt="tab_zbb_htdj_kc.gcnr_gczt">工程钻探
                        </asp:ListItem>
                        <asp:ListItem Value="gczj" ClassAtt="tab_zbb_htdj_kc.gcnr_zj">凿井
                        </asp:ListItem>
                    </asp:CheckBoxList>
                </td>
            </tr>
获取函数
  var gcnrtext = "";
            $("#<%=chkGcnr.ClientID%> span").each(function (string) {
                if ($(this).children().eq(0).is(':checked') == true) {
                    gcnrtext = gcnrtext + $(this).children().eq(1).text() + ";";
                }
            });

恶心变态的问题来了
CheckBoxList 初次加载带有span标签可以取到值， 第二次生成就没有span标签

所以此方法修改后为：
  $("#<%=chkGcnr.ClientID%> input").each(function (string) {
                if ($(this).is(':checked') == true) {
                    gcnrtext = gcnrtext + $(this).parent().find("label").text() + ";";
                }
              });

   <asp:RadioButton ID="rdoCk" runat="server" Text="初勘" GroupName="rdo" />
   <asp:RadioButton ID="rdoXk" runat="server" Text="详勘" GroupName="rdo" />

  if (document.getElementById("<%=rdoCk.ClientID%>").checked == true )
