[FlexJS] How to call external JS function from AS3 class (and first
make it compile)
Hi,
while we already need to solve how to make dialog polyfill work, I found a
new problem that hope you guys have already managed.
I need to put the following lines in my Dialog MDL component:
if (! dialog.showModal) {
dialogPolyfill.registerDialog(dialog);
}
I have dialog var in my AS3 so this is ok, but I don't have
"dialogPolyfill" var
So the question is...how make FlexJS aware of "dialogPolyfil" that is setup
by the JS loaded as an external resource so I can compile my AS3 class and
make it work in the browser?

The use case is that you want to get something up and running quickly that
the compiler won't complain about, even if there's no type-checking. If I
were to do something like this in one of my own projects, it would be
temporary so that I could focus on something else first, and I'd come back
and flesh things out later.
Another use case I should think is obvious: there's an actual global
variable or function loaded from a <script> tag or something that you want
to use in ActionScript:
package
{
/**
* @externs
*/
public function globalFunction(param1:String, param2:Number):Boolean {}
}

I didn't test it on anything other than a class. Feel free to try it and
maybe even fix it if it doesn't work.
I'm not sure I understand this particular use case though. If you are
accessing a third-party library, usually there is more than just a global
object in the APIs. Are you just trying to prevent renaming on something?

Is it only supported on classes? Is it possible to add it to variables or
functions in packages too? As an example, I think something like this will
be a common quick-and-dirty workaround for accessing JS globals.
package
{
/**
* @externs
*/
public var myGlobal:Object;
}

Unfortunately, there is more to it than that. The @extern goes on a
class. I pushed examples to the flex-tourjs repo and am in the process of
writing up a blurb on it.

Thanks for the various responses. Very helpful! :)
I'm just downloading Alex changes, so, If I understand ok with that
changes, the way to use dialog polyfill from MDL swc should be to add in
Dialog.as something like:
@extern
var dialogPolyfill;
as other var? maybe with public?
Thanks!

Looking forward to it, Alex. If people can write them in ActionScript
directly instead of converting Closure externs or TypeScript definitions,
that's going to be way easier!

And you could cheat a little bit and add it to missing.js in
flex-typedefs/js if you don't want to bother setting up a whole new
typedef SWC.
BTW, I will be checking in changes to Falcon that make it really easy to
use AS to generate typedefs.

If you don't mind the string property reference, that would be the easiest
way to access it. :)

window[“dialogPolyfill”].registerDialog(dialog) should do it.

For any JS libraries that you load with <script> in the HTML, you need to
make a typedef SWC and reference it on the external-library-path to expose
the APIs to ActionScript.
