在SWF外部单击时卸载外部加载的SWF

Question

我在舞台上有一个按钮，它使用Loader类加载外部SWF。我希望能够在用户点击它外面时，即在舞台上的任何其他位置卸载SWF。

到目前为止，我只有加载SWF的代码......

mybutton.addEventListener(MouseEvent.CLICK, fl_LoadExternalSwf);

function fl_LoadExternalSwf(event:MouseEvent):void
{
var my_Loader:Loader = new Loader();
var my_url:URLRequest=new URLRequest("pageFlip.swf");

//These listeners detect when the file has finished loading, and if the
//correct file is loaded.
my_Loader.contentLoaderInfo.addEventListener(Event.COMPLETE, finishLoading);
my_Loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);

//The load method then loads the SWF file into the loader object.
my_Loader.load(my_url);

//This function adds the external SWF to the stage.
function finishLoading(loadEvent:Event) {
addChild(loadEvent.currentTarget.content);
}

//This function displays a message if the file is not found.
function errorHandler(errorEvent:Event):void {
trace("file missing");
}
}

Answer 1

您可以使用unload()类

的Loader()

function unloadMC(myLoader:Loader, myURL:URLRequest):void {
 myLoader.unLoad(myURL);
}

unloadMC(my_Loader, my_url);

修改

您需要一个外部接口来调用“除了”swf之外的click事件。首先，您需要使用jQuery来实现

$(document).bind('click', function (e) {
 $('#yourSWFObject').clickOutside();
});

$('#special').bind('click', function(e) {
    e.stopPropagation();
});

点击方法。之后，您需要使用

从AS3应用externalInterface

import flash.external.ExternalInterface;
public function clickOutside() {
 unloadMC(my_Loader, my_url);
}
