如何在ActionScript3中删除Child？

发布于 2024-12-10 20:31:26 字数 602 浏览 0 评论 0原文

我每次都添加孩子，一旦添加孩子，当我添加下一个孩子时，上一个孩子就会被删除，这是我的目标。我试图删除孩子，但我的屏幕上没有显示任何内容。这是我的编码，

var tf:TextField = new TextField();
tf.text = chatData.message;<---------here i add the text dynamically
listChat.addChild(tf); // <----------------------------------here i added the child

var t:Timer = new Timer(150);
t.addEventListener(
TimerEvent.TIMER,
function(ev:TimerEvent): void
{
    tf.text = tf.text.substr(1) + tf.text.charAt(0);

}

);

t.start();
listChat.removeChild(tf);// <----------------------------------here i remove the child

 }

如何删除孩子？任何人都可以帮助我，提前致谢！

终于我得到了答案
这是我的编码

var myFormat:TextFormat = new TextFormat();
myFormat.size = 35;
var tf:TextField = new TextField();
tf.maxChars=100;
tf.text = chatData.message;
tf.defaultTextFormat=myFormat;
tf.autoSize = TextFieldAutoSize.LEFT;
tf.x = tf.y = 100;  
listChat.addChild(tf);
var t:Timer = new Timer(150);
t.addEventListener(
TimerEvent.TIMER,
function(ev:TimerEvent): void{
tf.text = tf.text.substr(1) + tf.text.charAt(0);    
}   
);
t.start();
if(listChat!=null)
for (var i:int = listChat.numChildren-2; i >= 0; i--)
{
listChat.removeChildAt (i);//here i remeve the Child
}

}

var myFormat:TextFormat = new TextFormat();
myFormat.size = 35;
