javascript - Prevent jQuery UI dialog from setting focus to first textbox

Question

I have setup a jQuery UI modal dialog to display when a user clicks a link. There are two textboxes (I only show the code for 1 for brevity) in that dialog div tag and it is changed to be a jQuery UI DatePicker textbox that reacts on focus.

The problem is that the jQuery UI dialog('open') somehow triggers the first textbox to have focus, which then triggers the datepicker calendar to open immediately.

So I am looking for a way to prevent the focus from happening automatically.

<div><a id="lnkAddReservation" href="#">Add reservation</a></div>

<div id="divNewReservation" style="display:none" title="Add reservation">
    <table>
        <tr>
            <th><asp:Label AssociatedControlID="txtStartDate" runat="server" Text="Start date" /></th>
            <td>
                <asp:TextBox ID="txtStartDate" runat="server" CssClass="datepicker" />
            </td>
        </tr>
    </table>

    <div>
        <asp:Button ID="btnAddReservation" runat="server" OnClick="btnAddReservation_Click" Text="Add reservation" />
    </div>
</div>

<script type="text/javascript">
    $(document).ready(function() {
        var dlg = $('#divNewReservation');
        $('.datepicker').datepicker({ duration: '' });
        dlg.dialog({ autoOpen:false, modal: true, width:400 });
        $('#lnkAddReservation').click(function() { dlg.dialog('open'); return false; });
        dlg.parent().appendTo(jQuery("form:first"));
    });
</script>

Add a hidden span above it, use ui-helper-hidden-accessible to make it hidden by absolute positioning. I know you have that class because you are using dialog from jquery-ui and it's in jquery-ui.

<span class="ui-helper-hidden-accessible"><input type="text"/></span>
