防止 jQuery UI 对话框将焦点设置到第一个文本框

我已经设置了一个jQuery UI模式对话框，以便在用户单击链接时显示.该对话框div标记中有两个文本框(为简洁起见，我只显示了1的代码)，它被更改为对焦点作出react 的jQuery UI Datepicker文本框.

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.

所以我在寻找一种方法来防止焦点自动发生.

<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>
