Creating a Flash and JavaScript Plugin Created Nov 30, 2009

Sounds like a reasonable approach. It's always a good idea to have a JavaScript API in the Flash plugin so that people can control, configure and script the Flash behavior via JavaScript.

You can use the [External] annotation to expose Flash methods for JavaScript access. Nothe that you will need to compile the plugin using the Flex compiler so that this annotation gets processed by the compiler - The Flash CS IDE does not do it.

Thanks for the quick response.

Don't know if ist makes a difference but i what to do is the following:
Click a button in Flash calls a JavaScript-function, the function changes the appearance uf the Flash-Plugin an delivers some variables....

So that users can change and configure the plugin with javascript, is not exactly what i'm thinking about. But i can imagine, that that it will work the same way and you don't see general problems.

But when I'm doining this, the user will have to add the .swf of the plugin and as well a .js, right?

Yes what you describe is certainly doable. I'd make the Flash plugin to generate an event when the button is clicked. Here's ActionScript code how it would do it:

_model.dispatch(PluginEventType.PLUGIN_EVENT, "onButtonClick");

This can be handled in JavaScript like this:

plugins: {
 myPlugin: {
    url: 'flowplayer.specialplugin.swf',
    onButtonClick: function() {
       // invoke a method in my plugin passing it some random parameters
       this.doStuff('foo', 'bar', true);
    }
)
}

Thanks for your help. sounds easy so far.
