Question

您好我正在使用 Flash Builder 4.6 为数据库创建应用程序和 AMFPHP 。我想在从AMFPHP检索数据时显示弹出窗口。并在执行完成后删除。

Answer 1

简单的想法是创建一个进度条＆amp;将它加载到弹出窗口中（它也可以像加载一样传递消息....）。在单击按钮上创建弹出窗口，然后在绑定值时使用removeallPopups（）;

Answer 2

另一种方法是在开始readProduct调用之前创建一个新的弹出窗口实例，并使用AsyncToken函数重新编译并在那里保存Popup实例。然后在结果处理程序中，您可以从ResultEvent.token对象中获取该实例，并仅关闭该实例。

    protected function button1_clickHandler(event:MouseEvent):void
    {
        var popup:IFlexDisplayObject = PopUpManager.createPopup(this, MyPopupComonent, true);
        //i want to show popwindow for slow process
        var token:AsyncToken = amf.readProduct();
        token.popup = popup;

    }
    protected function method1_resultHandler(event:ResultEvent):void
    {
        var popup:IFlexDisplayObject = IFlexDisplayObject(event.token.popup);
        PopUpManager.removePopup(popup);

        //Here the data is retrieved successfully then the popup is removed 
        myArraydata.removeAll();
        myArraydata = new ArrayCollection(ArrayUtil.toArray(event.result));
    }
