Hi Tracy,
There is no callFunction(..) like method for flash activeX or plugin. But
there is setVariable(..) method.
Yes, you can set a variable or setter from Javascript using setVariable
function. I have create a example, it allows you to execute flex function
from javascript...
It's very basic example but you can adopt similar approach and do it more OO
way by creating classes in JS and AS...
1) FlexJSExample.jsp
%@ taglib uri=FlexTagLib prefix=mm %

script language=javascript
//this function return to Flash ActiveX Object or Plugin depending upon
browser
//it takes care for browser type and returns the proper reference.
//Accepts the id or name of OBJECT or EMBED tag respectively
function thisMovie(movieName) {
// IE and Netscape refer to the movie object differently.
// This function returns the appropriate syntax depending on the browser.
if (navigator.appName.indexOf (Microsoft) !=-1) {
return window[movieName];
} else {
return window.document[movieName];
}
}
/**###**/
//success flag, set by flash/flex app
var bFunctionCallFinished = true;
//param delimiter, kind of unique string
var paramDelimiter = --$$###$$##$$--;
//this function would call a flash/flex function.
function callFlashFunction(functionName, paramsArray)
{
if(bFunctionCallFinished)
{
//Get the reference so activeX or Plugin.
var flashObject = thisMovie(flexApp);
bFunctionCallFinished = false;
flashObject.SetVariable(functionName, functionName);
flashObject.SetVariable(functionParams,
paramsArray.join(paramDelimiter));
flashObject.SetVariable(commitFunctionCall, true);
}
else
{
//if previous function call is still being run, you can use
setTimeOut etc to call it little later...
}
}

public function set commitFunctionCall(flag:Boolean):Void

BTW! Based on above principle, I made a JS-Flash libarary long back. Take a
look at it for an idea...

Subject: [flexcoders] Is there a javascript flashObj.callFunction(), like
setVariable?
Using javasript in a custom HTML wrapper, Is there flashObj.callFunction(),
like there is a setVariable() method?
Or will setVariable() work with a setter method? (Hmm, surely I can create a
setter in mxml, right?)
