Here is a working sample application that calls your flex sayWhat funciton from javascript.
It contains 4 files: ax.mxml, call_flfunc.html, ax.js and ax.css.
You should put the last three files and the generated ax.swf file in the same folder on your web server (or modify their path where they are referenced), and it will work.
ax.mxml: your main flex application's structure
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
width="300" height="300" backgroundColor="#bee3f6"
creationComplete="onCreationComplete()">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
public function sayWhat():void {
Alert.show("Hi");
}
public function onCreationComplete():void {
Security.allowDomain("localhost");
// binds this.sayWhat to the external interface, so when from
// javascript is called the compiled swf object's sayWhat function,
// it will be transferred to this.sayWhat.
ExternalInterface.addCallback("sayWhat", sayWhat);
// The next line tells the external interface (the parent application:
// browser window), that this application has finished loading, its
// ready to be used.
// In js there has to be a global method with this name.
ExternalInterface.call("onFlashAppInited");
}

I hope it's understandable, and you can work from it.

You might need an other kind of workaround in js to call the flash function from any browser.
Here i share my way to accomplish this (hope it is not deprecated yet...). You need a javascript class (i named it FO):
/**
*
* @param id
* @param swf
* @param width
* @param height
* @param scriptAccess
* @param allowFullscreen
* @return
*/
function FO(id, swf, width, height, scriptAccess, allowFullscreen){
this.id = id;
this.movie = swf;
this.height = height ? height : 180;
this.width = width ? width : 240;
this.scriptAccess = scriptAccess ? scriptAccess : "always";
this.allowFullscr = allowFullscreen ? "true" : "false";
this.obj = document.createElement("embed");
this.obj.src = this.movie;
this.obj.width = this.width;
this.obj.height = this.height;
this.obj.name = this.id;
this.obj.id = this.id;
this.obj.align = "middle";
this.obj.type = "application/x-shockwave-flash";
this.obj.setAttribute("quality", "high");
this.obj.setAttribute("bgColor", "#bee3f6");
this.obj.setAttribute("play", "true");
this.obj.setAttribute("loop", "false");
this.obj.setAttribute("allowScriptAccess", this.scriptAccess);
this.obj.setAttribute("allowFullscreen", this.allowFullscr);
this.obj.setAttribute("pluginspage", "http://www.adobe.com/go/getflashplayer");
}
FO.prototype = {
id :null,
width :null,
height :null,
movie :null,
scriptAccess :null,
allowFullscr :null,
obj :null,
addParam : function(name, value){
var p = document.createElement("param");
p.name = name;
p.value = value;
this.obj.appendChild(p);
}
};
You will need an initialization method (or extend the existing one):
// should be called on window.onload
function init() {
var flashObject = null;
if (isIE)
flashObject = document.getElementById("myMovieName");
else
{
flashObject = new FO("myMovieName", "ax.swf", 225, 200).obj;
// **app** is the id of a div / html container element,
// in which your <object> is positioned.
document.getElementById("app").appendChild(flashObject);
}
}
window.onload = init;
and for calling the desired method:
//somewhere else in your code:
if (flashObject)
flashObject.sayWhat();

When calling from javascript try:
myMovieName.sayWhat();
