如何觸發事件YesNo Alert Box？

Question

這是非常基本的，那里有示例 ，但我仍在努力。

我需要使用“是/否”選項來發出警報。
我需要在動作腳本中執行此操作。

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"); 
    }
}

這將返回Flash調試播放器的異常：

我已經嘗試了幾種代碼變體，但仍然會出錯。 對於這樣一個瑣碎的Q表示歉意，但感謝您指出任何錯誤以及最優雅的解決方法。

以下是pastebin（第31行）中完整代碼的代碼。

我本該多堅持一點。 下面的代碼修復：

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"); 
                             }
                         }
