JQuery selector for checked CheckBoxes in a repeater

<div class="checkGroup">
  <asp:Repeater ID="list" OnItemDataBound="OnPopulate" runat="server">
    <ItemTemplate>
      <asp:CheckBox ID="checkBox" runat="server" />
    </ItemTemplate>
  </asp:Repeater>
</div>

This will return all checked checkbox :

$(".checkGroup INPUT[type='checkbox']:checked")
