AS3 |事件监听器按删除按钮

Question

我需要一个事件监听器来按键盘上的删除按钮。

我尝试使用此代码：

stage.addEventListener(KeyboardEvent.KEY_UP, deleteItem);
function deleteItem(e:KeyboardEvent) {
   if(e.charCode == 46){
       trace('1');
   }
}

但不起作用。请帮帮我！

Answer 1

stage.addEventListener(KeyboardEvent.KEY_UP, keyboardEventUPHandler, false, 0, true);

function keyboardEventUPHandler(event:KeyboardEvent):void 
{
    if(event.keyCode == Keyboard.DELETE)
    {
        //Keyboard.DELETE = 46
        //do something
    }
}

Answer 2

stage.addEventListener(KeyboardEvent.KEY_UP, deleteItem);

应该是

stage.addEventListener(KeyboardEvent.KEY_DOWN, deleteItem);
