Button to navigate and unload swf

Question

I have the following code to load an external swf by clicking a button. It works fine.
btn_01_01.addEventListener(MouseEvent.CLICK, fl_ClickToLoadUnloadSWF);
function fl_ClickToLoadUnloadSWF(event:MouseEvent):void
var url:String = event.currentTarget.name+".swf";
fl_Loader.load(new URLRequest("loads/TEST_VID_AS3.swf"));
I also have a button that takes me to another place on the timeline.
this.btn_back_main.addEventListener(MouseEvent.CLICK,fback_main);
function fback_main(evt:MouseEvent)
MovieClip(this.root).gotoAndPlay("main");
But the loaded swf is still visible.
I would like that button to also unload the loaded swf.
Can anyone tell me if it's possible and suggest code?
Thank you in advance.

Answer 1

this should do it (assuming the btn to remove it is called "btn_remover"):
var ld:Loader = new Loader();
btn_01_02.addEventListener(MouseEvent.CLICK, v);
function v(e:MouseEvent):void {
     ld.load(new URLRequest("loads/TEST_VID_AS3.swf"))
     addChild(ld)
btn_remover.addEventListener(MouseEvent.CLICK, removeSwf);
function removeSwf(e:MouseEvent):void {
     ld.unloadAndStop();
firstly, i moved the Loader definition outside of the function (otherwise it gets removed at the end of the function and cant be accessed later)
then i added event listener to remove button to call removeSwf function - which calls unloadAndStop() on the loader object
fyi, i suggest you use more descriptive names for your buttons and functions otherwise you'll find it harder to work out whats going on if you come back to it after a break.
