Send array from Flash (AS3) to JavaScript

Question

Is it possible to send an array from Flash (AS3) to JavaScript using an ExternalInterface call?

I currently am calling a function multiple times from a 'for each' loop inside Flash but it goes too fast for the JavaScript to keep up.

My idea is to create an array of the attributes, pass that to the JavaScript function and then to loop through that in the JavaScript.

Thanks, Josh

Yes, it's possible.

http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/external/ExternalInterface.html#call()

... arguments — The arguments to pass to the function in the container. You can specify zero or more parameters, separating them with commas. They can be of any ActionScript data type. When the call is to a JavaScript function, the ActionScript types are automatically converted into JavaScript types; when the call is to some other ActiveX container, the parameters are encoded in the request message.

A quick test:

AS code:

if(ExternalInterface.available) {
    ExternalInterface.call("jsTest", [0,1,"two",{a:1,b:2}]);
}

JS code:

function jsTest(arg) {
    alert(arg);
}
