JavaScript :: Passing Object To Flex Using Callback Function
Jul 11, 2011
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 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.
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 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.
1. I am working on a project in ASP and I am making queries to a SQL db that returns data back in the form of xml. I am not in control of the db or how it returns data.
2. I process the XML within the ASP page and then I also process the data from within flash. I am therefore making two database calls for one page view.
3. I am trying to figure out if I can in anyway, pass an XML list from the page to flash so that I am making only one database call. The site is heavily hit and I am practically doubling the server load. Basically, the only way I think that may be possible is through javascript but not sure where to begin.
Here's the challenge: I have a Flash movie which will be embedded in a page using an unknown DOM ID that I want to be able to identify/store for callback in a JS function. My ideal user flow would be: User clicks button in Flash. Flash pauses any animations / video / sounds / etc. Flash calls an injected JS function to display a page-covering overlay experience. When user closes overlay experience, a callback method on the Flash object is called. Flash resumes playback.
The problem is, when AS3 uses the ExternalInterface.call("functionName", args...) method, there doesn't seem to be a DOM event triggered, and thus it is impossible to tell which object called a JS function, so having a "registerMe()" function doesn't seem to work. Basically, the injected JS function has no way to determine which DOM object to call, because the ID of the Flash object is unknown.
I am creating a flash website with as storefinder.. There is an input text field in flash and a search button which when pressed will load a javascript function that uses the input text var.
i can call the function using this method - getURL("javascriptpenMap()", "", "POST");
but how can i pass it the variable from my input text field?
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.
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'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 keep getting this error #2007 i want to parse the stage and pass a bullet object to a class function that function is called every ENTER_FRAME in the class itself
because the bullet object is added to the stage and on the bullet, there is a event listener to call a function in a class every ENTER_FRAME
but now i want to delete this bullet as it leaves the screen on the top because bullets in this game can only fly upward.
this is some of the code so far in the class itself:
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 ?
I'm building an AIR desktop application. At one point the application loads a popup window (an MXML component based on s:Window), which contains an mx:HTML component which loads a local (in the application directory) html file, blank.html. The relevant elements in blank.html are:
<script src="jw/jwplayer.js"/> <!--JW Player's JS-based Embedder--> <div id="jwtarget" /> <!-- the target that the embedder will use -->
Since the parameters I want to use are determined at runtime, I use the domWindow property to invoke the method which loads the player. Here's an example that works:
So I have a video that plays stream from a webcam,I will click a button and take a picture. I encode that picture using JPEGEncoder then I store it in a ByteArray.How do I send that data over to either a javascript function or a java class?I don't want to use the navigateToURL (URLRequest) method because that will redirect my page.Is there a way to send the data to a function while still staying on the same page?For example, make a asynchronous call to a javascript function or java method?
I was recently searching for a way to call the print function on a PDF I was displaying in adobe air. I solved this problem with a little help from this fellow, and by calling postMessage on my PDF like so:
//this is the HTML I use to view my PDF <object id="PDFObj" data="test.pdf" type="application/pdf"/> //this actionscript lives in my air app var pdfObj:Object = htmlLoader.window.document.getElementById("PDFObj"); pdfObj.postMessage([message]);
I've tried this in JavaScript as well, just to be sure it wasn't adobe sneaking in and helping me out..
I'm trying to have JavaScript call a function from my ActionScript.
ActionScript: import flash.external.ExternalInterface; ExternalInterface.addCallback( "playSong", playSong ); function playSong():void { var _sound:Sound = new Sound(); var _request = new URLRequest("music.mp3"); _sound.load(_request); _sound.play(); }
here is the action code I add to the last frame of the flash object
URLLoader("javascript:mainFunction();");
The object loads but the function is not called. I can call the function other ways such as using an "onclick = mainFunction()" event on a button for example.
I have a page with multiple flash objects which are written by a third party and thus can't be changed. They call a JS function but don't seem to pass any identifying parameters. Is there any way to determine inside the function which flash object called it?
Is it possible to pass file names from a running Flash application, which only purpose is to enable multiple-file-selection, to a JavaScript application which handles upload of all files to the server?I have examined various Flash upload solutions (like SWFUpload, Uploadify, etc.) and none of them meets my needs. I want an easy to implement solution (like Uploadify) which also lets me specify various parts of the HTTP request.
The reason I need this is because my upload form uses session cookies (for user authentication) and an CSRF token both passed to the server when uploading files.Is it technically possible to pass filenames (+ paths) to a JavaScript application which then handles the upload?
