Question

这是非常基本的，那里有samples，但我仍在努力。

我需要使用是/否选项发出警报我需要在动作中做到这一点。

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"); 
    }
}

这会使用flash调试播放器返回异常：

我尝试了几种代码变体，但仍然会出错。为这样一个微不足道的Q道歉，但感谢任何帮助指出什么是错误的，以及最优雅的方式。

Here is the code in its fuller context at pastebin (line 31).

我应该坚持自己多一点。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"); 
                             }
                         }

如何点火YesNo Alert Box？
