}

似乎“如果”不起作用......我如何检查是否有要删除的东西......
我放了完整的代码，“如果”在开头和结尾都带有**！

我通常有这样的功能：

private function remove(child:DisplayObject):void
{
    if(child && child.parent)
    {
         child.parent.removeChild(child);
         child = null;
    }
}

如您所见，它检查子项是否存在（不为空），然后如果它有一个父项，并且父项包含显示列表中的子项，如果是这样，它将删除它然后将其清空，您可能想要也可能不想要孩子null，那是你的选择。

var bathmos0:MovieClip = new oloioibathmoi[RankN[rankupday[0]]-1];

...这个变量 (bathmos0) 在你的函数范围内是本地的。当您尝试使用以下方法将其删除时，它在您的功能开始时不存在：

if(bathmos0 && bathmos0.parent)
{
bathmos0.parent.removeChild(bathmos1);
bathmos0= null;
}

如果要删除剪辑，请为其命名：

var bathmos0:MovieClip = new oloioibathmoi[RankN[rankupday[0]]-1];
bathmos0.name = "bathmos0";

...然后按名称将其删除：

var mc:MovieClip = getChildByName("bathmos0");
if(mc && mc.parent)
{
    mc.parent.removeChild(mc);
    mc= null;
}

要么这样，要么把你的bathmosN变量放在你的函数之外，这样当你尝试删除它们时它们就在范围内。

如果嵌套条件会更清楚一些，在检查其父级是否为 null之前检查目标 MovieClip 是否为 null。

此代码在逻辑上无法抛出空异常错误：

if(bathmos1 != null)
{
    trace("bathmos1 is not null");
    if(bathmos1.parent != null)
    {
        trace("bathmos1 parent is not null");
        bathmos1.parent.removeChild(bathmos1);
    }
    bathmos1 = null;
}

因此，借用 Neil，您的可重用函数将是：

private function removeIfExists($child:DisplayObject):void
{
    if($child)
    {
        if($child.parent)
        {
            $child.parent.removeChild($child);
        }
        $child= null;
    }
}

有什么错误吗？你是什​​么意思'不工作'？要删除孩子，您必须检查多个条件。尝试这个：

if(bathmos1 != null && bathmos1.parent != null && stage.contains(bathmos1)){
  stage.removeChild(bathmos1);
}else
    trace("bathmos1 is not null: " + bathmos1 != null);
    trace("bathmos1's parent is not null: " + bathmos1.parent != null);
    trace("stage contains bathmos1: " + stage.contains(bathmos1));
}
