Passing variable from javascript to flash

Question

I have a flash music player that I would like to accept a parameter via a button click on a website. I'm thinking I could do this with javascript but not sure how.

Does anybody have any sample code for both the javascript and what I would use to request the variable inside my actionscript code?

Thanks, I appreciate it!

You're going to utilize the flash.external.ExternalInterface class.

Adobe docs: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/external/ExternalInterface.html

A simple google search for "AS3 ExternalInterface example" will yield more than enough results to point you in the right direction.

In the flash add a callback for the javascript function:

import flash.external.ExternalInterface;
ExternalInterface.addCallback("sendTextToFlash", getTextFromJavaScript);
function getTextFromJavaScript(str):void {
    trace(str);
}

In the html/js call it:

<script type="text/javascript">
    var currentPage="Home";
    function setCurrentPage(newPage) {
        currentPage = newPage;
        SendDataToFlashMovie(newPage);
    }

Calling JS Function From Flash: getURL("javascript:myfunction();");

I'm having a hard time getting that guys code to work. I have FlashBug running and I'm looking for a trace. Nothing is happening. What's supposed to happen when you click the home button?
