Question

我有两个swf，A.swf和B.swf：B.swf是A.swf.i的孩子想要访问b.swf中的a.swf变量。这可能吗？我该怎么办？这个？请用例子说明。在此先感谢

loader.load(new URLrequest"b.swf"));
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded)
function swfLoaded(e:Event):void
{
 data= e.target.content;    //data is the String  i declared outside                
 mainContainer.addChild(loader);In this Loader i want to dispaly the data
}

Answer 1

是的，可能。

var myObj:Object = new Object();
var swfLoader:Loader = new Loader();

var swfFile:URLRequest=new URLRequest("b.swf");
swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoadedHandler);
swfLoader.load(swfFile);

private function swfLoadedHandler(e:Event):void {
    myObj = e.target.content;
    //trace(myObj.mcBanner.prevImage);
}

现在myObj var包含加载的SWF内容。你可以轻松访问。

假设这是b.swf中的文档类：

public Class B extends MovieClip {
   protected var _theVar:String;
   public function get theVar():String {
      return _theVar;
   }
   public function set theVar(value:String):void {
      if (value != _theVar) {
         _theVar=value;
         //do something here with the new value
      }
   }
   public function B () {
      super();
   }
}

在文档课程中：

//this will be inside a function that detects that the content has been loaded
var bContent = yourLoader.loaderInfo.content as B;
bContent.theVar = 'some value';

如果您只想将值传递给加载的swf，可以使用参数对象，请参阅 AS3 Pass FlashVars to loaded swf

在ActionScript 3中将数据从父级传递给子级？
