如何触发 YesNo 警报框事件？

Question

这是非常基本的，有示例在那里，但我仍在挣扎。

我需要使用是/否选项触发警报。
我需要在动作脚本中执行此操作。

Alert.show("Open new tab to search in Google Maps?",
"No places found", Alert.YES | Alert.NO, this, alertListener, null, Alert.NO);

function alertListener(eventObj:CloseEvent):void {

   if (eventObj.detail==Alert.YES) {
    Alert.show("You clicked yes"); 
    }
}

这会返回闪存调试播放器的异常：

我尝试了代码的几种变体，但仍然出现错误。 对于这样一个微不足道的问题表示歉意，但感谢您指出问题所在以及最优雅的方法的帮助。

我应该自己再坚持一点。
代码修复如下：

Alert.show("Open new tab to search in Google Maps?", "No places found", Alert.YES | Alert.NO, null, alertListener, null, Alert.NO);

                         function alertListener(eventObj:CloseEvent):void {
                             // Check to see if the OK button was pressed.
                             if (eventObj.detail==Alert.YES) {
                                 Alert.show("here"); 
                             }
                         }
