Question

我想在电影关闭或卸载时处理我的本地连接，我应该用什么事件来处理？

Answer 1

我不相信有，但我认为无论如何你都可以强制关闭。

不完全确定这将是多么简单，但这将是我最好的猜测。在实例化LocalConnection时，请务必将其包含在客户端中（或作为AS2中的属性）：

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

除此之外，我会尝试连接连接时包括这个：

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;

Answer 2

我猜你可以对JavaScript中的unload事件作出反应，并通过ExternalInterface在flex app中调用一些清理函数。虽然没有使用ExternalInterface，所以我不太确定。

Flex是否有主电影的onclose / onunload事件？
