Actionscript 3 AS3删除精灵对象的多个子对象

我在应用程序中有一个按钮，用户可以单击该按钮添加多个输入字段。函数如下所示

private var fieldHolder:Sprite = new Sprite();

private function addInviteFriend(event:starling.events.Event):void
{
    this.newFriendInvite = new TextInput();
    this.newFriendInvite.backgroundSkin = new Quad(Constants.STAGE_WIDTH - 80, 30, 0xd0d0d1);
    this.newFriendInvite.width = Constants.STAGE_WIDTH - 110;
    this.newFriendInvite.height = 30;
    this.newFriendInvite.text = "";
    this.fieldHolder.addChild(this.newFriendInvite);
    this.newFriendInvite.x = 0;
    this.newFriendInvite.y = this.fieldHolder.height;

    this.removeInvitedFriend = new Button();
    this.removeInvitedFriend.defaultSkin = new Image(Assets.getAtlasTexture("btn-delete"));
    this.fieldHolder.addChild(this.removeInvitedFriend);
    this.removeInvitedFriend.x = int((this.newFriendInvite.x + this.newFriendInvite.width) - this.newFriendInvite.defaultSkin.width);
    this.removeInvitedFriend.y = int(this.newFriendInvite.y);
    this.removeInvitedFriend.addEventListener(starling.events.Event.TRIGGERED, removeInviteFriendClick);

    this.addInviteFriendButton.y = this.fieldHolder.y + this.fieldHolder.height + 30 + 1;
}

private function removeInviteFriendClick(event:starling.events.Event):void
{
    var child:Sprite = event.currentTarget as Sprite;       
    this.fieldHolder.removeChild(child);
}

一切都很好，我可以添加多个输入字段，但问题是，当我单击删除按钮时，只有按钮本身被删除，而不是文本输入字段。我知道为什么只有按钮被删除，但我不知道如何在removeChild进程中包含textinput

我尝试创建另一个精灵来保存fieldHolder的所有实例，但没有成功。我也试着让孩子们离开，但也没用

谢谢

尝试将这两个元素添加到一个容器中，然后调用

removeChildren

private var fieldHolder:Sprite = new Sprite();

private function addInviteFriend(event:starling.events.Event):void
{
    var container:Sprite = new Sprite();

    this.newFriendInvite = new TextInput();
    this.newFriendInvite.backgroundSkin = new Quad(Constants.STAGE_WIDTH - 80, 30, 0xd0d0d1);
    this.newFriendInvite.width = Constants.STAGE_WIDTH - 110;
    this.newFriendInvite.height = 30;
    this.newFriendInvite.text = "";
    this.newFriendInvite.x = 0;
    this.newFriendInvite.y = this.fieldHolder.height;
    container.addChild(this.newFriendInvite);

    this.removeInvitedFriend = new Button();
    this.removeInvitedFriend.defaultSkin = new Image(Assets.getAtlasTexture("btn-delete"));
    this.removeInvitedFriend.x = int((this.newFriendInvite.x + this.newFriendInvite.width) - this.newFriendInvite.defaultSkin.width);
    this.removeInvitedFriend.y = int(this.newFriendInvite.y);
    this.removeInvitedFriend.addEventListener(starling.events.Event.TRIGGERED, removeInviteFriendClick);
    container.addChild(this.removeInvitedFriend);

    this.addInviteFriendButton.y = this.fieldHolder.y + this.fieldHolder.height + 30 + 1;

    this.fieldHolder.addChild(container);
}

private function removeInviteFriendClick(event:starling.events.Event):void
{
    var child:Sprite = event.currentTarget as Sprite;       
    child.parent.removeChildren();
}

调用

this.fiedHolder.removeChildren（）时会发生什么

在

removeinveitefriendclick

中，不会删除子项？它会删除所有输入和删除按钮，而不仅仅是单击的“组”
