Desperately need help and would be gretaful if someone could see if they can find what is wrong.

I am trying to trigger a swf movie embedded in web page by using a js function. This is a dry run using sample code I have found, i eventually just want the movie to play and stop via js instructions, when clicking an a href. Website is http://simplywebdzine.com/ASJS_test.html

The as3 code in the swf is:

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

THANK YOU

Make sure you add the allow script access param in your flash embed (normally that's the problem)

<param name="allowScriptAccess" value="always" />

Looks like you have a typo in the html code you linked to. You have this code:

<a href onclick="javascript:SendDahMovie();">trigger</a>

But the JS function you defined is:

function SendDataToFlashMovie(newPage){
    var flashMovie=getFlashMovieObject("myFlashMovie");
    flashMovie.sendTextToFlash(newPage);
}

Every time you click on the trigger link, no only your function is not called, but also the page reloads. So try fixing this name mismatch.

PS: By the way, your code actually works.

I ran this JS code from firebug:

SendDataToFlashMovie('testing');

And I can see the trace in flashlog.txt.
