Javascript :: Handling File Uploads With Google Gears?
Feb 18, 2010
I'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".

I code primarily in PHP and Perl. I have a client who is insisting on seeking video submissions (any encoding) from the public via one of their pages rather than letting YouTube do its job.Server in question is a virtual machine and I can adjust ini settings for max post, max upload size etc as needed.My initial thought is to use a Flash based uploader with PHP on the back end but I wondered if someone might have useful advice and experience on the subject?

I'm looking for a tool to facilitate mulitple webpage file uploads from a single file browse dialogue. I know this has been asked previously, but I can't find anything current.I'd like to check file size prior to upload, and I gather Flash is still the only way to do that cross-browser? Ideally, I'd like an upload progress metre.I'll be using Linux and Apache servers, but don't have access to install add-ons such as PHP APC. Again, I assume something flash-based is the only option there?
I've looked at SWFUpload, but that appears to be another of these projects where the developers have become quite zealous and turned a simple concept into a full suite of tools for the masses.It seems quite cumbersome and I don't think I want to use it for my purpose.I'd prefer not to have to write something from scratch for this.suggest a non-Flash alternative if there is one? I do need full cross-browser compatibility without too many layers of degradation, so anything HTML 5 probably isn't what I want.

The only tools/plugins I've seen online that allow for multiple files to be selected for upload through one single dialog box using a SHIFT or CTRL click action (as opposed to clicking on a single file per for file uploads) exist for controls made in Flash/.NET/Java, not just straight Javascript/HTML/PHP.
Why is that the case? I'd imagine that if possible, site developers would look to having less dependencies on different technologies rather than more.

You all know the new generation of fancy, mostly Flash-based file uploaders like SWFUpload that can show a progress bar while uploading - a great improvement especially for shaky and low-bandwidth connections.
However, these uploaders all bring their own logic of how to handle uploads on the client side. I am looking for an unobtrusive way to "fancify" existing, classical file uploads, i.e. introducing a progress bar to normal file upload forms.
Due to the architecture of uploading files, this is most likely not possible without some tweaking on the client side.
I am looking for a solution that keeps the tweaking to an absolute minimum, e.g. a component that adds itself to the onsubmit event of a normal form, performs the file upload, displays a nice progress bar, puts the resulting temporary (server side) file path into the form, and submits it. On the server side, I just have to modify my script to use the file path provided by the flash uploader, instead of $_FILES and consorts, and think about security for a moment.
This is not exactly what all the Flash-based uploaders do: They can use data from a form, but they do not provide possibilities to submit the form as is, what is what I'm looking for. I am looking for a (probably) Flash based upload function taken a step further.

I've been reading about the security restrictions for file uploads in Flash Player 10.According to the FileReference docs for upload(), the upload does not have to be triggered by a user-initiated action (the browse() does, but that's another story). If it did, that would force an awkward user experience for multi-file uploads, since only one upload can occur at once -- so the user would have to click (or press a button) once per file to initiate the upload, but only when the previous file had finished uploading.

The 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.

how 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?

I 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.

I 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.

I'm trying to extend KmlPlacemark in the Google Earth API. Google uses factory methods to create the objects so I can't do something like this:
KmlPlacemark.prototype.foo = fuction(){...}
I tried to simply add methods to each of the objects after they were created
function foo(){...}
placemarkObj.foo = foo;
but it throws

I am planning to build a web application highly based on Google Maps API. I am considering either using the Javascript version, or the Flash version. I would like to create an interface which will be quite rich. Should I go for JS version of the API or Flash one? Also I do not plan to purchase Flex Builder, so ideally I would like to use some free Flex SDK that supports ActionScript. What would you recommend? Is it more reasonable to use JS or maybe better use the Flash Version. What are the limitations, pros and cons?

I've been playing with the visualization API aka dynamic charts and I've found that the example at [URL] does not really work on localhost. That is, Error calling method on NPObject is thrown when a event is clicked (points A and B in the example aforementioned). I suppose that is a security issue on the server end (Google's flash base).Since that jsFiddle code is hosted on a domain, the note at the very bottom of the documentation should not apply:Because of Flash security settings, this (and all Flash-based visualizations) might not work correctly when accessed from a file location in the browser [URL] rather than from a web server URL [URL] .

which apprently used to work, but since they've made changes this doesn't... during tests firefox navigated to a page with the url javascript:_gaq.push [URL] was strange. Do I need to even use flash to ask GA to track the anchor? Is there a way i can point GA to track all anchors that are part of my page?

I have a flash file and am using google's suggested method for as2 event tracking like so:
getURL("javascript:pageTracker._trackEvent('Refferal', 'Join', 'Benefits for HCAs/APs');");
The problem is that instead of silently communicating, pageTracker._trackEvent() appears to return a boolean value. Every time I click the button which this is located on I leave the page I was on and end up on a page that just contains the word "true".how to get around this? It makes the flash unusable.

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.

JS-to-AS3 callbacks work in kinda asynchronous way right? So for example if I ask SWF to download some file, which may take some time (depending on the size of that file), and while it downloads it, ask it to do some other operation (suppose SWF has several callbacks for various purposes), what happens in this case? Does SWF continue to download file and handle my second request in a different thread maybe, or it crashes, or throws some error? I know this is a good case for some testing, but I wonder if anyone has already done that, or maybe there is public info on the case that I cannot find?

I need to execute some javascript string code from flash swf file using actionscript 3.
I read that it could be done by passing the javascript code to the parent html document , using externalinterface.call function. Then I assume it will be faster if I can declare functions in the javascript code in the HTML document in the first use of externalinterface.call funtion ; if flash code calls the javascript code repeatedly. So let me ask you how to do that. For details , any javascript to be loaded is unknown in design time and I can not prepare a javascript file to be loaded.

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?
