Question

我有一个弹出屏幕，玩家输入他们的名字然后点击OK。单击确定后，我希望将播放器的名称传递给主XML。我怎么能这样做？

以下是处理弹出窗口的主XML中的函数：

    private function NewHighScore():void{
        highScorePopup = PopUpManager.createPopUp(this, Popup, true) as Popup;
        highScorePopup.SetScore(playerscore);
        PopUpManager.centerPopUp(highScorePopup);
        playerName = highScorePopup.getName();
        trace(playerName);
    }

这是弹出的XML脚本：

        import mx.events.CloseEvent;
    import mx.managers.PopUpManager;

    import spark.events.TextOperationEvent;
    public var playerName:String;

    public function SetScore (playerScore:int):void{
        scoreDisplay.text = "You achieved a new high score of " + playerScore.toString();
    }

    protected function button1_clickHandler(event:MouseEvent):void{ remove(); }

    private function remove():void{ PopUpManager.removePopUp(this);}

    protected function titlewindow1_closeHandler(event:CloseEvent):void
    { remove();}

    protected function nameBox_changeHandler(event:TextOperationEvent):void
    {playerName = nameBox.text;}

    public function getName():String{
    return playerName;
    }

等待玩家输入他们的名字是一个异步过程，因此您必须等待弹出窗口调度的事件。由于弹出窗口自动关闭（从舞台上删除）一旦单击确定按钮，您可以在Event.REMOVED_FROM_STAGE事件的该弹出窗口上收听，然后才从弹出窗口中收集数据。不要从弹出窗口中删除事件监听器，这样你就不会泄漏实例。

private function NewHighScore():void{
    highScorePopup = PopUpManager.createPopUp(this, Popup, true) as Popup;
    highScorePopup.SetScore(playerscore);
    PopUpManager.centerPopUp(highScorePopup);
    highScorePopup.addEventListener(Event.REMOVED_FROM_STAGE,getPlayerName);
}
function getPlayerName(event:Event):void {
    event.target.removeEventListener(Event.REMOVED_FROM_STAGE,getPlayerName);
    var popup:Popup=event.target as Popup;
    if (!popup) return;
    var playerName:String=popup.getName(); // now the name will be populated
    // do stuff with the name
}
