使用jquery-ui对话框作为ASP的确认对话框:LinkBut​​ton(如何调用postbck)

Question

我想使用jQuery UI的对话框来实现一个确认对话框,当用户单击一个删除链接(使用一个实现asp:LinkButton)时会显示该对话框.
我正在使用如下所示的代码(从jquery ui文档复制):

<!-- the delete link -->
<asp:LinkButton ID="btnDelete" runat="server" Text="Delete"
  OnClick="btnDelete_Click" CssClass="btnDelete"></asp:LinkButton>

<!-- the confirm-dialog -->
<div id="dialog-confirm-delete" title="Delete?" style="display:none;">
  <p>Are you sure you want to permanently deleted the selected items?</p>
</div>

<script>
$(document).ready(function () {
    // setup the dialog
    $('#dialog-confirm-delete').dialog({
        autoOpen: false,
        modal: true,
        buttons: {
          "Delete all items": function () {
                 $(this).dialog("close");
                 // ===>>> how to invoke the default action here
              },
          Cancel: function () { $(this).dialog("close"); }
        }
    });

    // display the dialog
    $('.btnDelete').click(function () {
        $('#dialog-confirm-cancel').dialog('open');
        // return false to prevent the default action (postback)
        return false;
    });

});
</script>

所以在click事件处理程序中,我必须阻止LinkButton(回发)的默认操作,而是显示对话框.

我的问题是:如果用户点击对话框中的"删除所有项目"按钮,我怎么能调用删除链接的默认操作(回发)来执行回发？

好的,这是我的方法(它有效,但它可能不是最好的解决方案):

$(document).ready(function () {
  $('#dialog-confirm-cancel').dialog({
    autoOpen: false,
    modal: true,
    buttons: {
      "Delete all items": function () {
        // invoke the href (postback) of the linkbutton,
        // that triggered the confirm-dialog
        eval($(this).dialog('option', 'onOk'));
        $(this).dialog("close");
      },
      Cancel: function () { $(this).dialog("close"); }
    }
  });

  $('.btnDelete').click(function () {
    $('#dialog-confirm-delete')
      // pass the value of the LinkButton's href to the dialog
      .dialog('option', 'onOk', $(this).attr('href'))
      .dialog('open');
    // prevent the default action, e.g., following a link
    return false;
  });
});
