AS3参考按钮

Question

我该如何使这项工作？我需要从引用中删除单词Button，以引用将要着色的实际项目。提前谢谢。

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

现在我了解你的问题，我建议如下。

1. 在this和contentMain以及其他任何内容中都有单独的按钮方法。然后根据需要this[...]或contentMain[...]访问对象。

   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. 为您拥有的方法添加额外的逻辑。

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