AS3 - 获取上下文菜单选择

Question

如何查明选择了哪个菜单项？

cm1.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT,changeColor);
cm2.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT,changeColor);

function changeColor(event:ContextMenuEvent):void{
trace("cm1 or cm2?")
}

谢谢。

Answer 1

function changeColor(event:ContextMenuEvent):void{
  if(event.target == cm1){
    //Do something
  } else if(event.target == cm2){
    //Do something
  }
}

Answer 2

跟踪事件目标以找出当前目标（被单击的）

function changeColor(event:ContextMenuEvent):void{
trace(event.currentTarget);
}

Answer 3

如果可能，请向每个上下文菜单元素添加单独的侦听器：

cm1.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, changeColorCM1);
cm2.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT,changeColorCM2);

函数changeColorCM1(事件:ContextMenuEvent):void{ //CM1 }

函数changeColorCM2(事件:ContextMenuEvent):void{ //CM2 }
