Declaring function in flash form app

[meteoric]

May I know the different between the following function declaractions:-

==========
Style 1
==========

function test():Void {
trace("success");
}

==========
Style 2
==========

this.test = function():Void {
trace("success");
}

==========

It seems like there are some scoping differences.

I created a flash form app, where I have a root form (called "rootapp") and this root form has a child form (called "childform").

In my childapp, I'm trying to access a function from rootapp, but it seems like I can only get it to work with "style 2", but I don't know the reason.

==========
rootapp
==========

on (load) {
// style 1: cannot be refered from childapp
function test():Void {
trace("success");
}

// style 2: can be refered from childapp
this.test = function():Void {
trace("success");
}
}

==========
childapp
==========

on (reveal) {
_level0.rootapp.test();
}


Also, is there a way to reference rootapp without specifying "_level0.rootapp"? I tried "_root" and "super", but it doesn't work for me.

By the way, I'm using MX 2004 Pro.

Thanks for the help.

one diference by the function declaration is the order they are procesed :


X();
Y();
Y = function () {
trace("Y");
};
function X() {
trace("X");
}


the abowe will trace "X" just "X" bacause function "Y" isn't available at the point a call it

Hello Xeef,

Thanks for your reply.

I tried doing a trace on both rootapp and childapp's on(load) and on(reveal), it seems like rootapp's on(load) was executed before childapp's on(reveal). So, in my case both function declaractions (style 1 and 2 ) should work for me, because the function was declared before I invoked it.

However, I could only get it to work with style 2.
