actionscript-3 - AS3 参考按钮

Question

我怎样才能使这项工作？我需要从引用中删除单词 Button 以引用将被着色的实际项目。先感谢您。

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

既然我理解了你的问题，我会推荐以下内容。

1. this对 in和 incontentMain以及任何其他按钮有单独的方法。然后在适当的情况下通过this[...]或访问对象。contentMain[...]

   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) {
       ...
   }
