Html :: Handling JavaScript Calls To Window.open()- Not Using Native Windows - Adobe AIR
Jul 26, 2010I am developing an Adobe AIR application which uses both native windows and floating panels. Is is possible to enable the creation of a floating window instead of a native window when a JavaScript window.open() function is called?
It is required that all of the floating windows are contained within one native window, therefore the creation of more native windows is not suitable.
I have used a Custom HTMLHost class in order to enable the creation of a native window but I can't work out a way of creating a MDI window instead. I am using the flexMDI framework for my floating panel interface.
Professional :: Handling A Javascript Variable In Flash?
Jan 6, 2010The following bit of javascript writes and retrieves a cookie which counts a users visits to the page. Then using swfobject it both embeds main_banner.swf and passes the cookie value "visits" to it via flashvars. The trouble is in the actionscript below; the vallue has been passed (this is certain, because the .swf shows up rather than the alternative content)- but the .swf is stuck on the first frame rather than processing the cookie and sending the user to the appropriate frame label.

Professional :: Handling Flash Video Cue Points In Javascript
Dec 13, 2010how to get Javascript in an HTML page containing an FLV video to listen for cue points in the video? I understand how to get the cue points in, but most people only seem to want to handle the cue point events within Flash. I want to use Javascript to display a different text in a page element at each point. Does the method vary depending on what player you're using? How about when it's the standard Flash playback component? Does there need to be any special Actionscript in the SWF containing the FLV?
View 2 RepliesFlash :: POST To Opened Javascript Window And Have Close The Window
Nov 30, 2011I created a Flash application that reads POST data from a form. A user clicks the button, and the data gets posted to the flash app in a new window (_blank). Now takes the data and then spins a wheel to give users a prize. If they don't win a message pops up letting them know they didn't win. If they don't win, clicking the OK button needs to close the browser window.
I've tried a number of solutions and it seems that the only way to get this done is to launch the window with javascript and then use ExternalInterface.call('window.close'); to close the window from within the Flash actionscript (3) because otherwise the window won't close (I've tried just using window.close and window.close() with no luck)
I understand how to launch a new window with javascript, but I don't know how to simultaneously launch and POST data to that window (the Flash application has to have the POST data. Is this the best solution? Is there a way to close a browser window easier than what I'm describing?[URL]

Javascript 3 :: Can A JavaScript Function Detect Which Flash DOM Object Called It
May 20, 2011Here'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.

JavaScript :: Global Keyboard Handling - Not Hearing A To Z Keys?
Nov 11, 2009I am trying to use Javascript to intercept keyboard events, so I can do CMD-W for "close-window" and whatnot, inside a Flash application, so the Browser doesn't get to use them. Well, I am able to listen for ALT, CTRL, and CMD onKeyDown/onKeyPress events, but I am not able to listen to anything else...
Here is the code, in the index.html file from a Flex Project:
<script language="JavaScript" type="text/javascript">
document.onkeydown = function(event) {applicationKeyboardHandler(event)}
document.onkeypress = function(event) {applicationKeyboardHandler(event)}
function applicationKeyboardHandler(event) {
alert("Key Pressed")
} </script>
I would like to make it so it could listen to any key press, not just alt/ctrl/cmd.
Javascript :: Handling File Uploads With Google Gears?
Feb 18, 2010I've been using this method of file uploading for a bit, but it seems that Google Gears has poor support for the newer browsers that implement the HTML5 specs. I've heard the word deprecated floating around a few channels, so I'm looking for a replacement that can accomplish the following tasks, and support the new browsers. I can always fall back to gears / standard file POST's but these following items make my process much simpler:
Users MUST to be able to select multiple files for uploading in the dialog.I MUST be able to receive status updates on the transmission of a file. (progress bars)I would like to be able to use PUT requests instead of POST I would like to be able to easily attach these events to existing HTML elements using JavaScript. I.E. the File Selection should be triggered on a <button> click. I would like to be able to control response/request parameters easily using JavaScript.
An example of uploading code using gears:
// select some files:
var desktop = google.gears.factory.create('beta.desktop');
desktop.openFiles(selectFilesCallback);
[code]....
Edit: apparently flash isn't capable of using PUT requests, so I have changed it to a "like" instead of a "must".

View 3 RepliesJavascript :: Dynamically Resizing Flash Object To Fill Window?
Jun 21, 2010I have a Flash/Flex object (Flashlight-VNC), which I would like to dynamically resize to fit the entire window after pressing a button in the Flex app. This would preferably happen without restarting the Flex app (and therefore the VNC session). I would just use the built-in Flash fullscreen mode, however Adobe's somewhat silly security restrictions prevent keyboard input while in fullscreen mode.
How exactly can I do this? I'm already using SWFObject to embed the SWF, if that helps. I am open to any solution utilizing ActionScript, JavaScript, or both, however I am not all too familiar with ActionScript or Flex, and the AS-based solutions I have found involve extending a "Sprite" object to add resize functionality, which Flashlight-VNC does not seem to use.

Javascript :: Flash Games Don't Resize Properly In A Browser Window?
Apr 24, 2011Most flash-based browser games don't seem to resize properly when the user resizes their browser window (i.e. ctrl+mousewheel). Example of bad resizing: Boxhead The Zombie Wars. Please refrain from playing for a moment, lest you forget about my question.
Some (surprisingly very few) actually do resize properly. Example (at least in Chrome): D.N.8
Is there a simple or standard technique to accomplish proper resizing? How do you do it?

[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.
Javascript :: Catch A Window Close Event From Action Script/flash?

ActionScript 3.0 :: Function Handling Generic Vectors?
Jul 22, 2010I have this question regarding vectors. Is there a way where I can make a generic utility method which would for example, subdivide a vector into two vectors and would be able to handle all types of vectors, whether they contain <int> or <string> or <myClass>
for example:
ActionScript Code:
public function splitVectorIntoTwo(v:Vector.<T>):Vector.<Vector.<T>> {
var result:Vector.<Vector.<T>> = new Vector.<Vector.<T>>();
//Do logic
return result;
}
I don't know if this is possible but else it hinders our development quite a bit by using vectors since we can't use some generic utility methods as they will not accept generic vector types and you have to create a specific method for every vector type, one for Vector.<int> one for Vector.<string> etc.... With arrays, since they are not type-safe they can be passed within every such method.
ActionScript 3.0 :: Annoying Handling Of Function Pointers
Oct 31, 2010I'm not sure if you've noticed this, probably not, but function pointers in AS3 run much, much slower than calling the function directly. It's a recent finding, and an annoying one. I use function pointers a lot. An obvious example would be to easily change the behaviour of a certain object. Say I have a class that controls movement, it has a class level function variable called UPDATE (ie public var UPDATE:Function), and 3 or 4 actual functions it can point to.
This always me to quickly/easily change the behaviour of an object. Say for example I want an object to run on different movement code once it's collided with something, I can just do UPDATE = movement2; etc. However, a pointer for a function runs about 15 times slower than running the function directly, therefore I need a replacement. And I really have no idea why there is this absurd disparity in speed between the 2. With some variables, accessing a reference is faster than accessing the variable directly, obviously not with functions. What would you advise as a nice, simple replacement solution for the above example?
Javascript :: Allowing Flash Movie To Communicate To Containing Window Without Exposing Full ExternalInterface?
Oct 14, 2011I'm working on a site that allows administrators to upload arbitrary SWFs and embed them on the page. Administrators are in theory trusted, but I still want to protect against potentially malicious administrators or misguided administrators from harming the site.
A part of the functionality of the site is that the SWFs can communicate to the containing browser page when it's finished and for the page to react.
Now, I can think of two ways to do this:
Use ExternalInterface.addCallback to create a global callback named something like isComplete that does logic and returns true or false depending on whether the Flash app is in a completed state. Then, just do something like setTimeout to just call that function repeatedly. I don't think this would require me to open up allowscriptaccess to the movie. Embed the movie with allowscriptaccess and have the movie call something like ExternalInterface.call('done') when it's finished. This option seems like it requires me to open up allowscriptaccess, which is a potential threat since I can't control the SWFs that would be embedded with this directive.
