Actionscript 3 :: Javascript Callback In Chrome
Jun 18, 2011
I'm making a callback from javascript to a method on my swf. It works in Firefox with no problems, but in chrome the second parameter that's passed is always received as null? I've debugged my javascript and found that everything is working fine and the two values that are passed to the swf are correct at the point where the callback to the swf is made. At first i thought this might be a cross domain issue, but have ruled that out as if it were the case then the method on swf would just not be called at all. The second value is a binary string representation of an image and the length of the string that is passed is 101601, so i'm wondering whether there's possibly a limitation on the amount of data that can be passed? The first parameter is a much smaller string representing the file type and this always gets received successfully.

I have a Javascript API, which should be usable with GWT and Flex. Using the FABridge it is really easy to call Javascript methods from AS3 and vice versa. But when I try to register a callback to an AS3 method in my Javascript API I get stuck. Here is a short code sample:

I am pretty new to flex, so forgive me if this is an obvious question.Is there a way to open the Security.showSettings (flash.system.Security) with a callback? or at least to detect if it is currently open or not? My flex application is used for streaming audio, and is normally controlled by javascript, so I keep it hidden for normal use (via absolute positioning it off the page).
When I need microphone access I need to make the flash settings dialog visible, which works fine, I move it into view and open the dialog. When the user closes it, I need to move it back off the screen so they don't see an empty flex app sitting there after they change their settings.

I have a Flash movie embeded with swfobject in a html container. Through ExternalInterface I have registered a javascript function to fire callback to my flash app.
ExternalInterface.addCallback("notifyClose", notifyOnClose );
The javascript function is added as an event listerner to fire onbeforeunload.
<script language="JavaScript">
function getSWF(movieName) {
if (navigator.appName.indexOf("Microsoft") != -1){
[Code].....
I have tested in FF and IE. Firefox works as expected but not in IE. In IE I get notified in Flash with the onload message, but not onbeforeunload.

I'm trying to get javascript to talk to flash, but I haven't been able to get it to work.I've gotten flash to talk to javascript, but not the other way around. It seems as thought flash isn't listening to the javascript, or I'm doing something wrongPart of the AS3 to initially call the js:
ExternalInterface.call("showGal", slastSelectedNumber);
The js i'm trying to use is:
function showGal(dPicture) {
document.getElementById('fullsizegallery').style.display = 'block';
document.getElementById("flashGalleryContent").someFunctionName(dPicture);

I have a page that uses the jQuery.swfobject plugin to embed 5 flash items into a page and each flash item has a callback using externalInterface. The callbacks work when I have the js function outside of $(document).ready(function() but the jQuery animations do not fire - the ajax load however does. Does anyone know how to get the animations working too, code below:
function pageLoader(galID) {
$('#menu').hide();
$('#holder_gallery').load("feeds.php", {gallery: galID}, function(){

I have a flash application using callbacks to javascript functions (eg. when it receives some data over a socket, it'll call a js script which would change the content of a div according to that given data).
Afaik, there is no actual mutual exclusion in javascript so I'm not sure if I can/need to simulate something like :
[code]...
So, the question is, when are those callbacks called ? Are they simply queued to be executed right after the browser finishes its task or are they triggered randomly ?

My web application pass a javascript object to flex application using addCallback function.
when the flex application is in modal dialog in safari browser, the object in the flex application is null and when I open the flex application just in a new window, the object is passed correctly. But, I need the showmodaldialog to show the flex application.
The flex code:
ExternalInterface.addCallback( "handleEvent", handleEvent );
override public function handleEvent( event:Object ):Object {
Alert.show(String(event)); .....

I have a flex app and I am adding a callback method like this:
private function init():void
{
ExternalInterface.addCallback( "playVideo", playVideo );
}

However if I uncomment and run the alert first. I get no error and it works perfectly.My first thought was that the alert was buying time until the script could execute, so i tried to run the script inside a setTimeout() but did not work.

Am I using the code improperly or is there a flaw in SWFObject? If you go to the URL below you can see that it the flash file (an MP3 player) shows up perfectly fine in Chrome. However, in both Firefox and IE8 it loads a blank white box. If you mouse over the box the pointer changes to a hand as if its registering the buttons, just not actually displaying them. Link: [URL] (MP3 player should be displaying in the right-hand empty column)

This is a simple page I am trying to add a .swf to, with a small custom made js function I slapped up. With chrome the swf is pushed up and out of the navigator window and is missing the top half.
I have tried this quick and dirty approach to detect browser and set the proper background values for each browser:
var browser = BrowserDetect.browser;
var height = '';
var width = '';
switch (browser){
[Code].....
For the movie size in the embed tag: I have tried percents, I have tried pixels, quite a few different combinations. There is always at least one browser that chokes no matter how I set it. Right now it is chrome that chokes. Does anyone knowing the trick to these parameters mind clueing me in on a proper efficient method to integrate a .swf?
Maybe the outer html code is not properly structured and causes this? I am not specialised integration, I am mostly a back-ender, tried a few solutions online but this custom .js that sets values for <nosript> is the only way I managed to get this close to working crossbrowser.
My question basically, what are the clean efficient ways used by integrators to integrate swf cross browser, and is my approach workable if I set proper values?

It appears that the flash variables are not accessible in Chrome when Javascript is turned off. Having said that, Youtube seem to work fine, when I test other sites like www.nhs.uk it does not seem to work, nor does mine.
I am using the most recent version of Chrome on Windows. Is there anything special that I need to target Chrome, how do I resolve this issue ?

Chrome has bundled a "native" flashblock for a while, as has the android browser. swfobject reports that the flash player is available, even if the block is enabled for all sites. All I want to do is detect that a user is using native flashblock, and provide some messaging. Certain services, like the Facebook JS SDK, do not work without flash enabled for cross-domain communication, and do not provide methods of detecting failure. I know how to detect an extension/plugin like the original flashblock, but the native version does not appear in the navigator.plugins list.
Is there a way to detect if a user is running with a native flashblock enabled?

I'm working on a Google Chrome extension that monitors mouse events. For some reason the following javascript code in the extension's content script is causing embedded Flash content to break:
[Code]...
If you mousedown inside a Flash element, it never registers the mouseup and it appears as though you're still holding your mouse button down even though you've let go. At first I thought it was some kind of event bubbling issue, that this method was swallowing the event, so I tried returning true (and false for that matter) but it didn't seem to have any effect.

I'm just trying to understand a difference between IE, Chrome and Firefox. I have the following code on a page:
$('object').live('click', function(){
alert('Fired');
});
I then populate the page with some Flash controls (in my case, I'm using Uploadify). When I click on the Flash control, I see the alert in Firefox 4. However, I do not see the alert in IE8 or Chrome (I havent tested any other browsers).

I'm hitting a brick wall here, and it's driving me mad. Used to use ExternalInterface to call Flash functions from Javascript all the time, and now under CS5 (and the way it uses object id's instead of embed in html) it's stopped working for me in certain browsers. I put together a really simple program that has the person click a link in the browser that activates a javascript function that simply sends some text in to Flash to display in a TextArea. Here's the as3 code:

I was having an issue with a Flash AS3 SWF Preloader stalling in Google Chrome only, Mac or PC, when JavaScript is disabled. It's fine with JavaScript. I diagnosed that the contentLoaderInfo Event.COMPLETE was not being fired. The successful workaround was to use the ProgressEvent.PROGRESS to check when the bytesLoaded >= bytesTotal. This worked OK in a relatively simple Flash application, however I also have an MP3 player, using a loaded XML file, MP3s, a thumbnail and other images. I am reluctant to plunge into the same workaround without first asking the question - when the bytesLoaded >= bytesTotal IS THIS THE SAME AS Event.COMPLETE? Or could I be faced with an error when trying to access either the event.target.data or event.target.content (depending on using loader or URLLoader class as required) to get the object in question?

how to best handle the issue of not having enough permission inside of a Google Chrome Extension. I am interacting with the YouTube API, but I am not using swfobject.js, just using am embdeeded div. I do not believe this is introducing my security issue, but perhaps it is. In development, I had to navigate to Adobe's flash player security page and designate my development folder as a 'safe' location. In deployment, I do not have the ability to do this. I do not want my users to have to click 'Allow All' on flash player security, but I do not see another way to achieve my results.Seems to be a duplicate of SWFobject in a Chrome Extension - API Unavaiable but remains unanswered.Source: https:[url].....
To run: Pull from the repo, load up Chrome, click the wrench, go to extension, check 'Developer Tools' -> Load Unpacked Extension and browse to the folder.

I have flash resizing it's container div by using external interface to call the javascript:[code]Now this appears to work fine in every browser except chrome. For some reason after the div is shrunk back down to size, the flash player looks like it's frozen. It's actually not frozen because if you resize the window the flash player starts playing again and you can see it had made progress since it appeared frozen. This only happens in chrome. Does anyone have any idea why something like this might happen?The site so you can check it out yourself(yes I know it's a broken mess in IE, but I'm kind of ignoring that for now):[code]I've tried different window modes but that doesn't help. The problem is when it resizes the div back down because if I comment that line out the flash never appears to freeze. But I need to be able to resize the div...

I am integrating a flash module with Drupal using XMLRPC module. I am currently calling a node.save on Drupal(which creates a page in drupal), using Actionscript 2.0. On a flash button click, I am currently calling the node.save function. But ideally, I would like the function to be called first and only after the success of node.save, forward to the confirmation url. Right now, I am being forwarded to the page even without node.save being completed. I then have to refresh the page in order to see the results.
