AS3參考按鈕

Question

我該如何做這項工作？我需要從引用中刪除單詞Button來引用將被着色的實際項目。先謝謝你。

disagreeButton.addEventListener(MouseEvent.ROLL_OVER, mouseRollOver); 
contentMain.clickButton1.addEventListener(MouseEvent.ROLL_OVER, mouseRollOver); 

function mouseRollOver(e:MouseEvent):void { 
    var c:Color = new Color(); 
    c.setTint (0xFFFFFF, 1); 
    //the issue is this line: 
    this[e.target.name.replace("Button", "")].transform.colorTransform = c; 
} 

Answer 1

現在，我明白你的問題，我會推薦以下內容。

1. 有按鈕單獨方法this，並在contentMain，任何人。然後在適當情況下通過this[...]或contentMain[...]訪問對象。

   disagreeButton.addEventListener(MouseEvent.ROLL_OVER, mainMouseRollOver); 
   contentMain.clickButton1.addEventListener(MouseEvent.ROLL_OVER, contentMainMouseRollOver); 
   
   function mainMouseRollOver(e:MouseEvent):void { 
       mouseRolloverLogic(this[e.target.name.replace("Button", "")]; 
   } 
   
   function contentMainMouseRollOver(e:MouseEvent):void { 
       mouseRolloverLogic(contentMain[e.target.name.replace("Button", "")]; 
   } 
   
   function mouseRolloverLogic(item:DisplayObject):void { 
       var c:Color = new Color(); 
       c.setTint (0xFFFFFF, 1); 
       item.transform.colorTransform = c; 
   } 
   

2. 爲您擁有的方法添加額外的邏輯。

   if (this[...] != null) { 
       ... 
   }else if (contentMain[...] != null) { 
       ... 
   }
