Flex是否有主電影的onclose/onunload事件？

Question

我正在尋找處理我的本地連接，當電影關閉，或卸載，我應該做什麼事與此？

Answer 1

我不相信有，但我認爲你可以強制關閉無論如何。

不完全確定這將是多麼簡單，但這裏是我最好的猜測。當實例化你的LocalConnection，一定要包括這在客戶端（或作爲AS2屬性）：

function close() 
{ 
    myConnection.close(); 
} 

除此之外，我會包括這個試圖具有連接連接：

var commName:String = "MY_CONNECTION"; 
var myConnection:LocalConnection = new LocalConnection(); 

// Try to tell any open LocalConnection on this channel to close. 
// This may cause an AsyncErrorEvent, so be sure to add the appropriate 
// Error handling. 
myConnection.send(commName, "close"); 

try 
{ 
    myConnection.connect(commName); 
} 
catch(error:Error) 
{ 

    // If there is another connection already open on the same channel, 
    // that will cause an Error. I have had some luck catching that 
    // Error and then calling connect again. That said, you would be 
    // best to take precautions anyway. 
    try 
    { 
     myConnection.connect(commName); 
    } 
    catch(error:Error) 
    { 
     // Your connection cannot connect!!! 
     // DO SOMETHING!!! 
    } 
} 
myConnection.client = this;

我想你可以對JavaScript中的unload事件作出反應，並通過ExternalInterface調用flex應用程序中的某些清理函數。雖然並沒有使用ExternalInterface，但我並不確定。
