Communicating with JavaScript on the Page

For HTML5 games, how might I go about communicating with javascript that’s preexisting on the page. For example, maybe I have a function called submitData(data) . How would I call that within the game?

There’s a couple ways, one would be to use the ExternalInterface class. We have an example that shows how this could work, both with JavaScript and with Flash Player:

You can create a copy using the following command:

openfl create BrowserExternalInterface

Another way is to use untyped __js__ to add literal JavaScript into your code, so long as you are compiling to the HTML5 target:

#if html5
untyped __js__ ("submitData") (data);

There are also ways to use Haxe extern classes
