ActionScript 3.0 :: Passing Arrays From Javascript ?
Feb 2, 2007
I am working on a break through technology which brings together Audio DSP, Embedded, C/C++ and Javascript/AS3. I am in charge of getting the javascript/as3 done .
I need to send Arrays to and fro Javascript / Actionscript 3.I tried the javascript/as gateway from http://osflash.org/flashjs. It's done in actionscript 2 and I might have to migrate it to as3. I am not sure how long it would take.And I tried the ExternalInterface class in AS3. But it seems only strings can be passed using the addCallBack() and call() methods. Moreover I was not able to reslove the security issues when the flash player tried to communicate with the javascript.
I'm able to record sound with a Flash application embedded in my website, this audio is saved to a ByteArray, which I need to pass to Javascript in order to post to my server along with other required data.
I know I can use AS3 ExternalInterface class to communicate with Flash from Javascript, but what would be the appropriate format or variable type in javascript to hold the ByteArray, and how can I ensure that I won't lose much audio data when doing so?
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?
I'm having some trouble with a little database updating application that I'm working on. Basically, I'm trying to pass an array variable out of Flash and into PHP in order to update an SQL table. I seem to be having some trouble with differences in the way that AS and PHP handle array variables. how I can pass an AS array variable in a format that PHP will recognize?
Overview of Issue: A person will enter up to 8 words. Each word is then stored in a dynamically generated text box (responseTextArray[i]) within a dynamically generated movie clip (responseBubbleArray[i]). From here they will drag the bubbles into positions on the stage. Finally all of this information is to be stored in a database. To identify each entry, I put them into arrays. How can I pass all these arrays to a PHP script,so that I can store them in a MySQL database? Or, is there a better way to accomplish what I have described? The plan is to have each user entry and its attributes (response time, response text, x position of bubble, y position of bubble) stored as a row in the database.
I have been told that it is dangerous to pass arrays into functions because doing so can cause memory leaks.Could someone please explain how and why this happens?
I have an array in my one class (loadXML) and i want to use it in a different class (player). I have my two classes here. This is not working though. How can i use songsArray in player.as? Its all good and dandy in loadXML, the array is being populated.
I have a SWF movie ("bits.swf") with an array ("things") variable in it. I use loadMovie to load bits.swf into my main movie. Q: how can I read/use/transfer the values in array "things" from my main movie?
I'm trying to send an object to javascript that can have an arbitrary number of elements included, including associative arrays. If I create the following object:[code]The numeric indexes of the array will trace out, while the string based indexes will not. Does anyone have any idea why this might not be working? (Running CS4, I can't find the option to change my signature)
Is there a way that I can pass the value of app: or appstorage: to a javascript file which has been included via URLRequest? I have a web application with an HTML5 video player, and I've been asked to get it to work as an AIR app. So far so good, except that there is a bug in jPlayer that requires you to use absolute file paths for media if you're using flash fallback. I need to get the file path of the app: or appstorage: directory on a users machine, and pass that to javascript so that the player can find my videos.
I m using AS2.0 which interacts with the JSP to get three values using a JS call.After that from the AS i m trying to call a servlet by passing these values but the values are coming as NULL or undefined.
I have a simple standalone application written in Visual Basic that I'm porting to a browser based application using PHP/javascript. The original VB application has some simple embedded flash games with token and point counters. The token and point values are being passed as variables between the application and the game.
I'm trying to achieve the same effect in my PHP port without modifying the actionscript code( using the variables in actionscript that already exist). Below is Visual Basic code that's loading a value from a database and posting that value to flash using FlashVars:
Passing a JavaScript array to Flash?I want to pass an Array from JavaScript to a Flash movie. My goal is to create an Array of URLs to pass to Flash and once the Array is in Flash, I can access those URLs in the movie.I know how to send a variable to Flash using the "Embed" and "Object" tags using "FlashVars".
<PARAM name=FlashVars VALUE="song=song_URL">
but I want to somehow send and array, or maybe can I call a function that creates the Array I want to send?My reason is to have an HTML developer come back and change the Array values and that will change the Flash Array, so they don't have to edit the Flash movie.
My goal is to pass a variable from JavaScript to ActionScript in my swf file. I am using Flash CS3 and AS3. Currently all I want is my test to work where I mouseover a text link and a function is called with a passed variable in my swf file.
Here is my code: // test.html - Cropped out the excess code <html><head> <script type="text/javascript"> function myMovie(movieName) { [Code] .....
ExternalInterface.addCallback("sendToActionScript",fromJS); only once, or inside of my function onEnterFrame(event:Event) loop? I tried both, but since I can't get it to work I don't know which one is the proper one.
i have developed a flash website, just user interface, now i have a contact form in my swf file . can anyone help me in embedding this swf file in html and getting values out of swf file on html page and printing on another html page, i just need help in getting values and out of swf file to html.
I have an HTML/JavaScript Adobe AIR app which needs to be listening for data coming in from an external process.I could have the AIR app itself invoked by the external process. If anyone knows how this could be done in such a way that AIR would then continue to listen for messages/events from the process which invoked it, then I would like to hear about it.Failing that, can I set up some kind of endpoint in AIR itself to accept data through?'ve experimented with a Native Process, and while having AIR launch the process allows it to read data in, the native process itself to be externally accessible, plus it must be able to write to STDOUT for Adobe AIR to receive.
I am having a flash application where I want to send parameters to it via the javascript from a defaul.aspx page. I have a parameter called Id where it can accept alphanumeric values. The query string in the url works fine if I enter just numbers for the Id, and takes me to the specific page related to that id , but if I enter a combination of numbers and characters like 001A , it does not work.
This is the code I used <script type="text/javascript"> function getQueryVariable(variable) { var query = window.location.search.substring(1); var vars = query.split("&"); for (var i=0; i<vars.length; i++) { [Code] .....
And then passed the flashvars into swfobject.embedSWF. I also don't want to change anything in my mxml files in flash side.
i`m trying to send variables from this .swf on level2 of the main movie to another swf that loads onto a javascript popup. i`ve tried using the GET and POST methods with no success.the popup script, first layer:
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.
I've made a XML based Mp3 player using Flash 8 and AS2. The player is working just fine, I mean playing song on previous and next button. Now I want to enlarge this and my idea is to list all the mp3s on a PhP page and allow user to listen to any song randomly. This means, user can click any song name and that song will start playing in the player.
My problem over here is; the song listing and the player will be on one single page and clicking on any song wont reload that page to play the selected song but just reload the content of the mp3 player.
I know this can be done in Javascript. My thought on this is: On clicking each song name, I need to call a JS function and pass to it the "ID" of the song. This JS function needs to pass "that ID" to the swf which will play the song.
Keeping aside the complexity involve in ActionScript to fetch the song name as per the passed ID, I need to know how to pass this ID from JS to AS
Our web application has a feature which uses Flash (AS3) to take photos using the user's web cam, then passes the resulting byte array to PHP where it is reconstructed and saved on the server. However, we need to be able to take this web application offline, and we have chosen Gears to do so. The user takes the app offline, performs his tasks, then when he's reconnected to the server, we "sync" the data back with our central database.
We don't have PHP to interact with Flash anymore, but we still need to allow users to take and save photos. We don't know how to save a JPG that Flash creates in a local database. Our hope was that we could save the byte array, a serialized string, or somehow actually persist the object itself, then pass it back to either PHP or Flash (and then PHP) to recreate the JPG. We have tried:
On a page I have a an iFrame and a swf, I've been trying to use ExternalInterface to pass values from the swf to the iFrame, anyone ever tried this and had any luck? I won't be able to post any code until tomorrow, will update then if needed.Here is a visualization of what I need to accomplish, perhaps if it can't be done the way I said someone will have a suggestion of another way to accomplish this.
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)); .....
Is there an existing javascript library for relaying key press events in the browser (or certain divs) into flash? I am hoping there might be a library kind of like this one for mousewheel events?Something like this handles javascript keyboard shortcuts great. I suppose I could just listen for those events and pass the ones I want into flash?These are great examples, however, if flash has focus, then javascript keystrokes are lost. How can you ensure that all key events go through javascript?
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?
