Passing variable from JavaScript To AS3 (Flash CS3)

Passing vars from JS to AS3 is really easy, but it’s not as easy as it was with AS2.
Here I use the excellent SWFObjects (I use it in all my web projects now) to pass variables to the Flash Player:
so.addVariable("var1", "value1");
so.addVariable("var2", "value2");
Now to get the values with AS3 when you already know the variable name:
var myValue1:String = this.loaderInfo.parameters.var1;
var myValue2:String = this.loaderInfo.parameters.var2;
If you want to trace all the variables (names and values) passed to the Flash Player:
for ( var theName:String in this.loaderInfo.parameters ) {
var theValue:String = this.loaderInfo.parameters [theName];
trace(“from JS :”+ theName+” “+theValue);
}

Does it really differ comparing to AS2? I just pass all the variables I need using well known FlashVars and access them in any Class via Application.application.parameters associative array (e. g. Application.application.parameters.userId).

[...] ciao, in realta’ questo e’ un falso problema perche’ questi parametri eventualmente GIA’ esistono in loaderInfo.parameters: http://www.metah.ch/blog/2007/07/04/…as3-flash-cs3/ a occhio e croce direi che a livello di document class gli unici parametri che puoi passare in fase di creazione sono quelli via FlashVars.

Thanks for the trace function. I’ll snippet it for later use. How can you send a var from AS3 to Javascript? Or modify a Javascript var from within Flash. I want to grab the width and height from the onmetadata of a FLV, resize the player according to those values, and then send out those values to be used with swfobject. I have all the vars placed and AS3 complete, I just need to know how to send them out so swfobject can read them. Thanks!!
