Question

我试图使用按钮进行文字输入，但到目前为止我只能输入一个数字。（如果我单击另一个按钮进行第二次输入，则会删除第一个输入。）有没有办法解决这个问题？

我在这里添加了我的代码和图片，以显示我想要制作的内容。

我非常感谢你的帮助！

<mx:Button x="18" y="116" label="1" width="20" height="20" fontSize="7" click="one(event)"/>
<mx:Button x="37" y="116" label="2" width="20" height="20" fontSize="7" click="two(event)"/>
<mx:Button x="56" y="116" label="3" width="20" height="20" fontSize="7" click="three(event)"/>
<mx:Button x="18" y="135" label="4" width="20" height="20" fontSize="7" click="four(event)"/>

<mx:Button x="56" y="173" width="20" height="20" label="ent" fontSize="7" click="ent(event)"/>

public function one(event:MouseEvent):void {
        numberCopies.text = "1";
    }
    public function two(event:MouseEvent):void {
        numberCopies.text = "2";
    }
