        }
    }
}   
}

这是我的main.as代码。

这是我在maintimeline上加载SWF的代码。

addEventListener(Event.ADDED_TO_STAGE, init);

function init(event:Event):void 
{
    trace('try dispatch');
    dispatchEvent(new Event("clickHandle",true));
}

尝试调度工作，但它没有回到主要启动“返回root”。有什么想法吗？

THX！

只要所有动画片段调度事件都添加到显示列表中，这应该可行。这让我觉得可能正在添加的事件监听器不起作用。尝试将trace语句添加到代码块中，如下所示：

if ( swfName.name == 'topNavigation' )
{
     trace("adding listener");
     swfContent.addEventListener("clickHandle",topNavigationClickHandler);
}

我希望这个if条件失败，因此永远不会创建你的监听器。此外，您需要向回调方法“topNavigationClickHandler”添加一个函数参数，以接受该事件作为回调参数。您还没有这样做，这是一个错误，当收到事件并将其分派给回调方法时，它将在运行时抛出。你还没有看到这个，因为你的听众从来没有调用过回调。所以你必须像这样解决这个代码：

private function topNavigationClickHandler(e:Event):void
{
    trace('Back to root');
}

另外我只想补充一点，你设置这个监听器的if条件似乎有点多余，因为你已经知道你期待导航swf，因为你明确加载它。另外我不相信name属性会像这样设置。通常，名称仅在编译之前在IDE内部设置，如果不是，则在运行时动态生成。可能更有用的是检查加载的SWF的URL以查看它是否包含“topNavigation”或swf名称。你可以这样做：

var swfUrl:String = myLoader.contentLoaderInfo.url;
if (swfUrl.search("topNavigation") != -1){
   //Match found, add listener for navigation
}

调度事件不会触发:(
