c# ie 设置radio选中状态

                                     <asp:RadioButtonList ID="ZONGZHENSHU" runat="server" CssClass="chkTable"  RepeatDirection="Horizontal" RepeatLayout="Flow" TabIndex="8">
                                            <asp:ListItem  Value="4" Selected="True">四针&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</asp:ListItem>
                                            <asp:ListItem  Value="5">五针</asp:ListItem>
                                      </asp:RadioButtonList>

$('#ContentMain_ZONGZHENSHU_0').prop("checked", "checked");

ie 下需要使用prop设置选中状态

$('#ContentMain_XUANZESIZHEN_0').removeAttr('checked');

去掉选中状态
