Hello =)

so i'm buidling my asp.net page and i have a radiobutton list control on the page. i'm trying to figure out the best way to capture, via javascript, the value selected in the list.

here's what the control HTML looks like:
<asp:radiobuttonlist id="IdRBList" style="Z-INDEX: 126; LEFT: 448px; POSITION: absolute; TOP: 264px"
				tabIndex="4" runat="server" Font-Names="Arial" Font-Size="Smaller" Width="112px" AutoPostBack="True">
				<asp:ListItem Value="1" Selected="True">Bundle ID</asp:ListItem>
				<asp:ListItem Value="2">Container ID</asp:ListItem>
				<asp:ListItem Value="3">Storage ID</asp:ListItem>
