Question

I have a SWF file emedded withing a HTML page. Trying to do a simple operation – go to and play certain frame in SWF using javascript. I’m using ExternalInterface to do this but for the life of me can’t get the two to communicate.

I add all the code but when clicking on the link which calls javascript, it says my flash object is undefined?

Here’s the ActionScript code:

import flash.external.*;

function getFromJavaScript(frame:int):void 
{
 gotoAndPlay(frame);
}

ExternalInterface.addCallback("sendtoFlash",getFromJavaScript);

Here’s the javascript:

function getFlashMovieObject(movieName){
if (window.document[movieName]){
    return window.document[movieName];
}
if (navigator.appName.indexOf("Microsoft Internet")==-1){
    if (document.embeds && document.embeds[movieName])
        return document.embeds[movieName];
}
else{
    return document.getElementById(movieName);
}
}

function sendtoSwf(numb)
{
  var flashMovie = getFlashMovieObject("tour-flash");
  flashMovie.sendToFlash(numb);
}

And here is the embedded SWF:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="600" height="335" id="tourFlash" align="middle">
<param name="movie" value="/media/Assets/Flash/tourFlash.swf" />
<param name="quality" value="high" />
<param name="bgcolor" value="#ffffff" />
<param name="play" value="true" />
<param name="loop" value="true" />
<param name="wmode" value="window" />
<param name="scale" value="showall" />
<param name="menu" value="true" />
<param name="devicefont" value="false" />
<param name="salign" value="" />
<param name="allowScriptAccess" value="sameDomain" />
<!--[if !IE]>-->
<object type="application/x-shockwave-flash" data="/media/Assets/Flash/tourFlash.swf" width="600" height="335">

Any ideas? I’m totally stumped! For an example of problem, have a look here: http://www.onehealthfitness.com.au/get-started/virtual-tour.aspx

Seems like you are using the wrong value in the getFlashMovieObject(“tour-flash”) call, there is no object named “tour-flash” in your code, is there?

Besides that, I would recommend that you add a mute button, so a visitor can turn of the sound. I tend to leave pages that plays sound I can’t stop.
