ExternalInterface.addCallback
when communicating with flash from javascript is there a special setup that is required for flash.
the function in my actionscript (flash) is never called (the trace is never executed). i have been
searching for examples and help and everything i read looks like this should work.
all i am trying to do is send a text string to flash from javascript.
can anyone help me on this?
thanks
ACTIONSCRIPT 3.0 (code)
i have a flash program with just a dynamic text item named myTxt.
import flash.external.ExternalInterface;
import flash.display.*;
if (ExternalInterface.available) {
trace("external call okay");
ExternalInterface.addCallback("sendTextToAS3", receiveTextFromJS);
}
//Set up Javascript to Actioscript
function receiveTextFromJS(t:String):void {
trace('here');
myTxt.text = t;
}
