删除不同级别的孩子As3

Question

我已经在舞台上添加了许多对象（在Achievements.as类中）来创建成就板。当有人按下后退按钮时，我想从main.as类中删除所有的孩子。另外，有没有办法创建一个自定义textField类，其中每个textField.selectable = false，而不必分别分配给每个。

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

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

     } 

我得到的错误

1119: Access of possibly undefined property descripTxt through a reference with static type Achievements.

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删除儿童类

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

achievementback.RemoveTextBoxes()

我不得不稍微修改代码并注释掉设置框中的文本以使其运行（因为我缺少一些代码）但是，我的问题似乎是文本框被删除但你的绿色形状留在舞台上。添加一个矢量来保存所有这些并将它们添加到remove函数中。

我也不得不将您的自定义类更改回MovieClip和TextBox，因为我没有这些源代码。

Answer 2

它应该是：

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]); 
     } 

更新 你甚至添加这些的DisplayObject到矢量阵列？
