Question

我有一个类文件，我想多次调用它。它是一个名为PopupDialog的类，它扩展了sprite。删除它并再次添加后，旧的也会出现。我需要完全删除旧版本。这是我的代码：

function onSettings(event:MouseEvent):void {
    addChild(popupDialog);
    popupDialog.init(spWidth, spHeight, dialogSettings);
    popupDialog.addEventListener(CustomEvent.PASS_PARAMS, onProcessedEvent);
    spWidth = spWidth - 50;
    spHeight = spHeight - 50;
}

function onProcessedEvent(e:CustomEvent):void {
    popupDialog.removeEventListener(CustomEvent.PASS_PARAMS, onProcessedEvent);

    if (e.btnName == "close") {
        removeChild(popupDialog);
    }
}

这实际上无法删除该类。我尝试将其设置为null然后我开始遇到其他一些问题。

试试这个：

var popupDialog:PopupDialog;

function onSettings(event:MouseEvent):void {
    popupDialog=new PopupDialog();
    addChild(popupDialog);
    popupDialog.init(spWidth, spHeight, dialogSettings);
    popupDialog.addEventListener(CustomEvent.PASS_PARAMS, onProcessedEvent);
    spWidth = spWidth - 50;
    spHeight = spHeight - 50;
}

function onProcessedEvent(e:CustomEvent):void {
    popupDialog.removeEventListener(CustomEvent.PASS_PARAMS, onProcessedEvent);

    if (e.btnName == "close") {
        e.currentTarget.parent.removeChild(e.currentTarget);
    }
}

希望它有所帮助！
