Javascript - Getting Checked Input Values In A Specific Div

Here is my div that is contained more than once by my page:

<div class="formContainerDiv" style="width:165px">
<table>
<tr>
<td colspan="2">
Assign To<br />
<asp:CheckBoxList ID="CheckBoxListLoginUsers" runat="server">
</asp:CheckBoxList>
<br />
Note<br />
<asp:TextBox ID="TextBoxNote" runat="server" TextMode="MultiLine" Width="150" ClientIDMode="Static" class="textBoxNote"></asp:TextBox>
<br />
</td>
</tr>
<tr>
<td>
<input type="button" class="saveAssignment" value="Save"/>
</td>
<td style="text-align: center;">
<a href="javascript:void(0)" class="formContainerDivClose">Close</a>
</td>
</tr>
</table>
</div>

And that's my jquery function:

$(".saveAssignment").click(function () {
var div = $(this).parents(".formContainerDiv");
......
});

I can select the appropriate formContainerDiv. But I need to get the values of checked checkboxes and the value of TextBoxNote.
