AS3陣列按鈕嵌套

Question

我有按鈕的列表：

agreeButton disagreeButton container.clickButton1 container.clickButton2

Container是另一個影片剪輯和它裏面是最後的2個按鈕。

我該如何把它放在數組中，並將所有相同的監聽器應用到它們中的每一個？

var buttonArray:Array = new Array("agreeButton", "disagreeButton", "container.clickButton1", "container.clickButton2"); 
for (var i:int=0; i<buttonArray.length; i++) { 
    this[buttonArray[i]].addEventListener(MouseEvent.ROLL_OVER, mouseRollOver); 
    this[buttonArray[i]].addEventListener(MouseEvent.ROLL_OUT, mouseRollOut); 
    this[buttonArray[i]].addEventListener(MouseEvent.CLICK, mouseClick); 
} 

Answer 1

保留對按鈕的引用並將它們添加到數組中。

var agreeButton:Button = new Button(); 
var disagreeButton:Button = new Button(); 

//... Code that will add the above instantiated buttons to the canvas 

var buttonArray:Array = new Array(agreeButton, disagreeButton); 

for (var i:int = 0; i < buttonArray.length; i++) {  
buttonArray[i].addEventListener(MouseEvent.CLICK, mouseClick); 
} 


private function mouseClick(event:MouseEvent):void { 
    Alert.show("Boom!"); 
} 

Answer 2

我會做一個button類，每個這些按鈕擴展。在按鈕類中添加eventListeners。

例子：

原諒我，如果有事情不對的，我沒有在AS3編碼了一段時間。

class MyButton extends Button 
{ 
    public function MyButton() 
    { 
     this.addEventListener(MouseEvent.ROLL_OVER, mouseRollOver); 
     this.addEventListener(MouseEvent.ROLL_OUT, mouseRollOut); 
     this.addEventListener(MouseEvent.CLICK, mouseClick); 
    } 
    //... Add mouseRollOver, mouseRollOut, mouseClick methods 
} 

你各個按鈕

class DisagreeButton extends MyButton 
{ 
    public function DisagreeButton() 
    { 

    } 
} 

class AgreeButton extends MyButton 
{ 
    public function AgreeButton() 
    { 

    } 
} 

一旦你實例化所有的事件監聽器將被應用到每個按鈕。
