AS3 数组按钮嵌套

Question

我有一个按钮列表：

同意按钮 不同意按钮 容器.clickButton1 container.clickButton2

Container 是另一个影片剪辑，里面是最后两个按钮。

我怎样才能把它放在数组中，并让所有相同的监听器应用到每个监听器上？

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

保留对按钮的引用并将它们添加到数组中。

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

我会创建一个由每个按钮扩展的button 类。在按钮类中添加eventListeners。

例子：

如果这有什么问题请见谅，我已经有一段时间没有在 AS3 中编码了。

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
}

您的个人按钮

class DisagreeButton extends MyButton
{
    public function DisagreeButton()
    {

    } 
}

class AgreeButton extends MyButton
{
    public function AgreeButton()
    {

    } 
}

实例化按钮后，所有事件侦听器都将应用于每个按钮。
