Access flashvars from a loaded swf

Posted in: Library

To access the flashVars from a swf loaded into another swf use:
var test:String = String(stage.loaderInfo.parameters.myFlashVars)

SwfBuilder

An import point: This will not work unless the loaded swf has already been added to the display list.

Consider this code in your main swf, where code in frame one of loaded.swf tries to access a FlashVar:

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
loader.load(new URLRequest("loaded.swf"));

function completeHandler(event:Event):void
{
addChild(loader); // here's where your swf gets added to the display list
// Handle other init tasks
}

This will not work, because the code in frame one of loaded.swf will have already executed when completeHandler() is called. To get this to work, you have to move the addChild(loader) line:

var loader:Loader = new Loader();
addChild(loader);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);
loader.load(new URLRequest("loaded.swf"));

function completeHandler(event:Event):void
{
// Handle other init tasks
}

Hey thanks very much for adding this. I'd just assumed the user wouldn't run the code until that point, but really I should've clarified as you have. Cheers.
