是否有一种优雅的方法来暂时抑制jQuery事件？使用这样的代码：

$(element).unbind(event, function1).unbind(event, function2);
// code for which the event is suppressed
$(element).bind(event, function1).bind(event, function2);

但是，一个Ajax访问是特殊的

function message(text, callback) {
  if (text == undefined) {
     $.unblockUI();
     return;
  }

  // $().unbind('ajaxStop', $.unblockUI).unbind('ajaxStart', $.blockUI);
  $("#message_text").html(text);
  $.blockUI({message: $("#message")});
  $("#message_ok").click(function() { 
    // $().bind('ajaxStop', $.unblockUI).bind('ajaxStart', $.blockUI);
    $.unblockUI();
    if (callback != undefined) callback();
  });
}
