Javascript :: External Interface Callback Not Listening?
Jul 14, 2011
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:
I have been at it for two days now and have not been able to resolve this issue. I am trying to call an AS3 function from JavaScript via ExternalInterface API which is simply not working at all. If I to call a JavaScript function form html loaded swf, it works beautifully.[code]
I have a series of 10 external interface callbacks that are called through javascript and load mp3 files. The problem is, someone is able to click these while my pre-load function is running and it causes multiple files to load. Is there a way to disable the callbacks while the pre-load function is running?
ExternalInterface.addCallback("receiveText1", receiveText1); function receiveText1(value:String):void { channel.stop(); channel2.stop();
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 ?
Several months ago for a project at work i developed a video player using flash, external interface and swfobject.js. I used external interface to facilitate communication between javascript and actionscript. This works great. Currently I am working on an extension to this that requires me to extrapolate logic from what i already written. I am using the same swf file in both applications, but in the extension i can't get the flash object to recognize my calls. Since i am using the same swf object i know that my problem is in the javascript, i just don't know where. I am using the JQuery Library. Without further adieu here's my code.
I have a flash player with an external javascript interface: reloadData() I'm calling that function via Javascript when editing information on the page - basically to keep data on the page and in the player in synch. The reloadData() function works fine when the player is hosted locally. When we move it to the CDN (Amazon Cloudfront), the player loads successfully, but the external javascript interface no longer works - console.log(player) reveals the following:
<object type=,"application/x-shockwave-flash" data="[our_cloudfront_url].swf" width="920" height="404" id="player" style="visibility:visible;"> Uncaught TypeError: Object #<an HTMLObjectElement> has no method 'reloadData'
I know there are a lot of things that behave differently when working with items on a CDN, but we're using a CNAME to point to the cloudfront distribution (buildid.ourdomain.net => distributionid.cloudfront.net)
We have a flash game embedded in a web page (using SWFObject v2.2) and there are some links on the page that call into the flash in the following manner:
window.document["flashObjectId"].flashMethod();
This has worked great on all browsers we have tried including IE7 and 8, however on IE9 it generates the following error: "SCRIPT438: Object doesn't support this property or method".
It does work in compatibility mode so I tried adding a meta tag to tell IE9 to use compatibility mode by default, however that didn't work because our game runs in an IFrame within Facebook.
I have tried referencing the flash object every way I could think of in the Javascript but I always get that same error message in IE9.
I will call flashObject.httpRequest to complete a http request via flash. The problem is there is no reference about httpRequest is an async method or sync. It is important for my application.
private function httpRequest (uri:String, param:String="", method:String="GET"):void { var
Is there a non-polling way for Javascript to command Flash right when its external interface is ready? In Actionscript, I've registered a function for Javascript to call:[code]SWFObject lets you run code when Flash has been successfully embedded through a callback. I attempt to run $ ('flash Player'). doStuff in this callback, but it claims it's undefined. It seems that Flash needs some time to boot up its external interface. So I've been using a polling hack to find out when the external interface is ready:[code]There's a visually perceptible delay in the execution of doStuff and it makes my overall code structure muddy.
I need to call a function in JS that's expecting a JSON object. Can I do this from External Interface? The company's example (after the include file url) in HTML looks like this:
//there's an js include URL earlier// Shopwithme.Initialize({ "id":"prod1234",
[code]...
But, I need to dictate these vars through Flash. How do I call this function using External Interface?This is my EI code, but I'm obviously off base, since it's not working:
I am looking for a simple and straightfoward example of how I can pass the value of a variable into flash using javascript.Specifically, I'd like to use javascript to pass the filename of an external video file that I would like to load into my flash movie.I'd also like to call a function in the SWF that plays the movie once the filename as been passed to the flash movie.External Inferface looks like the way to goI've found a few decent AS2.0 examples, but converting them to AS3.0 has proven difficult and many of the examples are much too complex for what I am trying to do.
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 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'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'm trying to call a function in my ActionScript from my JavaScript, I've managed to successfully do this with another flash file but in the current one it's failing for some reason. I'm using jQuery SWFEmbed, this is my JS code:[code]The ExternalInterface.call work, and the trace outputs true, I have no idea what's going on.If you could also tell me how I can pass parameters to a ExternalInterface callback.
public function callFromJavaScript():String { test.label='dfdsfsdf'; return "1"; } public function init():void {
[Code]...
I have no clue wich one are crossbrowser compatible (cant install IE to test out)I have tried multiple but i cant get them to work(in any browser), im probably using the wrong id, ive been trial & erroring for a couple of hours but i don't have anything working.(i heard there was a problem with ExternalInterface.addCallback on a local file system?, should i upload the swf? < is the flex code right& problem = javascript/html side?)
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.
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(){
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'm currently working with soundmanager2 in an IE/flash context (not html5). The issue is that audio playback of mp3 content does not occur for the following case where the 'onload' callback function is defined as null OR as a function that does almost nothing.
I have a flex app and I am adding a callback method like this:
private function init():void { ExternalInterface.addCallback( "playVideo", playVideo ); }
[code].....
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.
I have an event listener that is listening for the end of an eternal audio file. I want to move to the next page after an external audio file has completed playing: here is the code I have so far:
This seems to work intermittently. Sometimes it will, and other times it won't. Is there anything wrong with my code or theory. Is there a better way to do this that will yield more consistent results? Or do I need to import any Flash Events?
My company has some software which we use to acquire data and interact with some hardware. If we wanted to put a mockup on a website which allows the user to get a feel for the UI (gather some data, change some settings etc.), what are some good methods to do so?I'm thinking either some clever javascript or flash. I've done some JS before but only to style elements of a page. I did some stuff with flash about 8 years ago and found it really fiddly.
So my questions; Are javascript/flash reasonable solutions for this or is there something better. What is likely to be the simpler/quicker route? Is there a better way to achieve the end result?] The demo doesn't need real data, just some fake/dummy example stuff is fine.
I am using in AS3 "External Interface ". When I call the JS function that is on the same page as swf everything works fine.
I added a link in the html page to an external JS file, when I move the JS function to the external JS file the website crushes.
I would prefer to have all my JS functions on an external file so I can use them in the future in other project and it also makes it easier for me to update the site.
how to call a JS function that is on an external file from AS3?
$('#trailer-dialog').mediaelementplayer({ enablePluginDebug: false, // remove or reorder to change plugin priority plugins: ['flash','silverlight'], // specify to force MediaElement to use a particular video or audio type
