        $(".div_soru").first().show();
        $(".onceki").click(function() {

            if ($(this).closest(".div_soru").next(".div_soru").html() != null) {
                $(this).closest(".div_soru").hide();
                $(this).closest(".div_soru").next().show();
                if ($(this).closest(".div_soru").next().next().html() == null) {
                    $(".bitir").show();
                    $(".sonraki").hide();
                }
            }
        });
    });
</script>

                            <td id="bitir" class="bitir">

                            </td>
                      </tr>
                 </table>
            </div>
        </div>
    </ItemTemplate>
    <FooterTemplate>
    </FooterTemplate>
</asp:Repeater>

This script hide radio groups. And I show them one by one with using next and prev button. I want to show an error message if a radio in one of radio gruop is not select. How can I current radio group selected value.

I try this but this is getting radio value from the first radio group.

var selectedRadios = $(".div_soru_wrapper input:radio:checked").val();

I think I cant explain clearly. I hope you understand what I want to do :) Thanks.

If you want to check if there is a checked radio button in the currently visible group, the :visible selector can help you:

if ($(".div_soru_wrapper:visible input:radio:checked").length) {
    // There is a checked radio button in the currently visible group.
} else {
    // There is no checked radio button in the currently visible group.
}
