Question

我在舞台上（在Achievements.as类中）添加了许多对象来创建成就板。当有人按下后退按钮时，我想从main.as类中删除所有子节点。另外，有没有办法创建一个自定义textField类，其中每个 textField.selectable = false ，而不必单独将它分配给每个。

public static var texts:Vector.<TextField> = new Vector.<TextField>();
public static var titleTxt:Vector.<TextField> = new Vector.<TextField>();
public static var descripTxt:Vector.<TextField> = new Vector.<TextField>();
public static var rewardTxt:Vector.<TextField> = new Vector.<TextField>();
public static var achCoins:Vector.<MovieClip> = new Vector.<MovieClip>();

for (var j:int = 0; j < 30; j++)
        {
            achCoins[j].x = 240;
            achCoins[j].y = 45 + j * 70;
            addChild(achCoins[j]);
            descripTxt[j].x = 0;
            descripTxt[j].y = 30 + 70 * j;
            //descripTxt[j].antiAliasType = AntiAliasType.ADVANCED;
            descripTxt[j].defaultTextFormat = tf2;
            descripTxt[j].text = descriptext[j];
            descripTxt[j].embedFonts = true;
            addChild(descripTxt[j]);
            titleTxt[j].x = 0;
            titleTxt[j].y = j * 70;
            //titleTxt[j].antiAliasType = AntiAliasType.ADVANCED;
            titleTxt[j].defaultTextFormat = tf3;
            titleTxt[j].text = titletext[j];
            titleTxt[j].embedFonts = true;
            addChild(titleTxt[j]);
            rewardTxt[j].x = 200;
            rewardTxt[j].y = 30 + j * 70;
            rewardTxt[j].text = reward[j].toString();
            rewardTxt[j].setTextFormat(tf1);
            rewardTxt[j].embedFonts = true;
            rewardTxt[j].textColor = 0x000000;
            addChild(rewardTxt[j]);
            texts[j].text = Main.achievement[j] + "/" + totnum[j];
            texts[j].setTextFormat(tf1);
            texts[j].x = 200;
            texts[j].y = j * 70;
            texts[j].embedFonts = true;
            addChild(texts[j]);

        }

然后我使用此代码删除孩子

for (var k:int = 0; k < 30; k++)
        {
            removeChild(achievementback.descripTxt[k]);
            removeChild(achievementback.titleTxt[k]);
            removeChild(achievementback.rewardTxt[k]);
            removeChild(achievementback.texts[k]);

        }

我收到错误

1119：通过a访问可能未定义的属性descripTxt 参考静态类型成就。

for (var i:int = 0; i < 30; i++)
        {
            texts.push(new TextField());
            titleTxt.push(new TextField());
            rewardTxt.push(new TextField());
            descripTxt.push(new TextField());
            achCoins.push(new coinSmall());
        {

在Achievements.as Class

中

public function RemoveTextboxes(){
for (var k:int = 0; k < 30; k++)
    {
       removeChild(descripTxt[k]);
       removeChild(titleTxt[k]);
       removeChild(rewardTxt[k]);
       removeChild(texts[k]);
    }
}

在Main.as类中

achievementback.RemoveTextBoxes()

这是我的整个成就课

} 数组描述文本：数组acharr：数组titletext：数组所有内容都有正确的内容，但它是很多文本所以我把它拿出来发布这个

以下是我用来从Main.as中删除子项的代码

function achievementExit():void
    {
        removeChild(back1);
        removeChild(coin_sm);
        removeChild(coinAmt);
        removeChild(completed);
        removeChild(achTit);
        removeChild(achback);
        achievementback.RemoveTextBoxes()
        removeChild(achievementback)
        removeChild(scrollPane);
    }

我不得不稍微修改代码并注释掉你在框中设置文本的位置以便运行（因为我错过了一些代码）但是我的问题似乎是文本框被删除但是你的绿色形状停留在舞台上。添加了一个向量来保存所有这些并将它们添加到remove函数。

        public function RemoveTextboxes(){
        trace("removing")

                removeChild(graphix[k]);
            }
        }
    }
}

我还必须将自定义类更改回MovieClip和TextBox，因为我没有源代码。

Answer 2

应该是：

for (var k:int = 0; k < 30; k++)
        {
            achievementback.removeChild(achievementback.descripTxt[k]);
            achievementback.removeChild(achievementback.titleTxt[k]);
            achievementback.removeChild(achievementback.rewardTxt[k]);
            achievementback.removeChild(achievementback.texts[k]);
        }
