Load and remove an external SWF.. i've a problem to remove it

I load an external swf in this way

PHP Code:

---

var termini_Loader:Loader = new Loader();
addChild(termini_Loader);
    

var termini_url:URLRequest=new URLRequest("termsnconditions.swf");
termini_Loader.load(termini_url);
    
addChild(termini_Loader)
termini_Loader.name="terms" 


---

This external swf haves a close button that i want to use to kill itself. I want to put the code inside the external swf itself, not in the principal swf that loads it.. then i've wrote

PHP Code:

---

termini.closebtn.addEventListener(MouseEvent.CLICK, function()
{
    (root as MovieClip).parent.removeChild(getChildByName("terms"))
}) 


---

but when i test it from the principal swf, this is the error
TypeError: Error #1009: Cannot access a property or method of a null object reference

What i've wrong?

You cannot use removeChild on the loaded swf, because it was not created that way. You can either remove the Loader object or unload the Loader object using that close button.

i don't understand.
If i apply the removeChild in the principal swf, so:

Quote:

---

var termini_Loader:Loader = new Loader();
addChild(termini_Loader);
removeChild(termini_Loader);

---

it works perfectly... so is it possible to use removeChild

In which movie is this line:
termini.closebtn.addEventListener(MouseEvent.CLICK , function()

external

This is what you need to have in your loaded swf:

function lHandler(e:Event):void
{
var myClip:MovieClip = e.currentTarget.parent as MovieClip;
if(MovieClip(myClip.parent.parent.root) != null)
{
MovieClip(myClip.parent.parent.root).removeChild(L oader(myClip.parent.parent));
}
}
termini.mc1.addEventListener(MouseEvent.CLICK, lHandler);

Works ;)

but i want to understand what it do exactly

PHP Code:

---

var myClip:MovieClip = e.currentTarget.parent as MovieClip; 


---

my MovieClip is the entire "termini" movieclip, right?

but myClip.parent.parent.root i don't understand at what refers to
and in any case, if i want to climb up until the root, isn't more correct write "(root as MovieClip).getChildByName("..... " ) ?

myClip ---> refers to termini
myClip.parent ---> refers to loader initialized in the principal swf
myClip.parent.parent ---> refers to root of the principal swf
myClip.parent.parent.root ----> ?????

myClip is just one shortcut to avoid writing out everything. Important is myClip.parent.parent.root, because it refers to the main timeline of the parent movie and holds the Loader. From there you can remove the Loader. You should avoid getChildByName if you can, because it is not the actual id of the clip. The best is if you use trace(something) to see what the actual objects
