Javascript :: When Does A Browser Initialize Flash?
Dec 15, 2010
I am working on optimizing a page that has Flash on it. I am using optimization practices like moving Javascript to the bottom to not block. Removing inline scripts. And minimizing HTTP requests with minified css and js.The majority of the pages content is in the flash, so loading it as soon as possible is the goal. Currently there is a 2 ~ 3 second delay before the flash is even rendered (using firebug profiling)
I am wondering at what point in the page load does the browser start initializing flash on the page? Is it once the DOM element containing the flash has been rendered? Is it once the complete onload event has been fired? I imagine it probably differs with each browsers as well.
I'm wondering if its possible to do what I'm thinking, and if it is possible, does anyone know of a flash object that does what I need? I know a Flash object can provide a javascript API to interact with it, what I dont know is can Flash send an email directly without the need to talk to the webserver to do so? If thats possible would it not be possible to write a flash object that did nothing but provide an API to send emails? Has such a thing been created that is out there for others to use?
I'm looking to create a email form on a web page but the site is static (no server scripting). In my situation server scripting is not possible as there is no server, the site is 100% client side on a CD/DVD/USB Stick.
I'm using an embed flash player in a web page and I want to scale it to browser window.hen I put "height: 100%" in the flash parameters, I get a blank page.This is the code of the page :
I have a website with a simple Flash animation behind some text and semi-transparent images as a background. I have used swfobject to embed it and set wmode opaque to make it display correctly in most browsers.For browsers without Flash, the user gets a static background image instead and would not know they were missing anything. However, Android users get the flash background on top of everything as per the known issue with how Flash content is rendered in the Android browser making the site unusable.
I have added a crude browser sniff javascript function to the swfobject code to prevent it from loading for any user agent whith 'Mobile' in it:
<script type="text/javascript"> if (navigator.userAgent.indexOf('Mobile') == -1) {[code].....
The only problem I have left is for Android users browsing with 'Mobile View' turned off as the user agent pretends to be a desktop version of Safari (I think). I do not wish to disable the Flash animation for all Safari users. Is there a way of blocking it for just Andriod users - even if they have 'Mobile View' disabled?
Possible ideas include:detecting the Flash version with JavaScript or Flash. Does Android use specific versions (version numbers) of Flash which are different from the desktop equivalent? blocking the specific user agents used by Android devices with 'Mobile View' disabled.
My webpage loads a background flash which will connect to the server using socket. If a user open multiple windows/tabs of my website, the server will get multiple socket connections. Any idea of how to make sure that only one socket is connected from the same user and same browser?
I am thinking of using Javascript to monitor the window close event, if a window that was connected to the server is closed, one of the other windows will try to connect to the server. But I can't find a way to listen to that event.I was thinking of Flash's LocalConnection too, but can't find a way to assign unique connection names and let other Flashes know.
I was wondering how to achieve the native scrollbar effect which TheFWA (thefwa.com) has managed to do pretty well (I am not a fan of Flex scrollbars).and implemented the technique, as I am calling a JS function through ExternalInterface every time, when the flash object changes size. This JS function simply resizes the div which holds the flash object, which creates the native bars.Unfortunately, when I resize quite rapidly (from 800 to 1800 height, for instance) the flash object simply gets warped for several milliseconds (as if it hasn't changed its size, but simply got pulled in all directions). After these milliseconds, things get back to normal, but the whole situation is really visually annoying.
Originally I thought that it's simply a timing issue, but after a bunch of attempts to set a delay, the effect was the same ... just delayed.How can I resolve that? I know it's technically possible. Just take a look at TheFWA, and see how smoothly flash and the browser are communicating with each other to make the native scroll bars work, without any flickering, or mismeasurement
I need to play WAV, MP3, MP4 and SWF files using Flash Player plug-in in Internet Explorer, FireFox, Chrome and Safari. Please give some suggestions on this.Is there any way to play this formats using JavaScript and HTML??I tried with and tag also but, Chrome, Firefox and Safari is required Quick Time Player to play this formats. I need to use only Flash Player.
I've run across several websites, including mine, that prompt users to download Flash even though their browser cannot install it. I want to avoid this confusing messaging by detecting whether a mobile browser can install Flash, not whether it has Flash.
Some known mobile browsers that can't install Flash are:
iOS Safari Android Chrome beta Android Firefox
Instead of building an ever-changing list of Flash installability, I would like to detect this in a general way in Javascript.
i have a swf file of width 1000 and height 700. i want to show the swf file in full screen of the browser it self (not like videos plying full screen). i tried like the following
1) get user screen width and height using java script using the functions available (screen.availHeight and screen.availWidth) the screen size is available by using the functions but not applying to the flash object
2) tried giving 100% for both height and width in object code that also not working
I have a Flash file embedded into HTML - the objects inside are place based on the browser's screen size.Most of the time I don't want a scroll bar, as things are correctly placed, but once the browser window gets too small it'd be nice to have it.So, the main question: can I have a Javascript code listening for the browser window, then adding a scroll bar if it's smaller than a certain number?
I've been trying to understand how flash animations or a Java Applet work within a browser. I can think of a couple of ways - The Flash Player/Java Applet are machine code that's dynamically linked it, and given some parameters about the area of the screen that belongs to them; after that, they run within the same process space. The browser exposes an API that the player/applet use to talk to it and they live in a separate process. (Presumably they talk via sockets?) The API could correspond to openGL/X11/some custom calls.
These possibilities still don't explain things like how a button click can make the player full-screen, how it can play music, how it can inspect the DOM, etc. For that matter, is the video displayed by decoding to a sequence of images, and rendering them one at a time, or is there a more efficient way, e.g., of pushing the deltas in the image? The Wikipedia page on Java Applets
(1) talks about how the applet is run in a sandbox (presumably a separate process), but it doesn't say how the browser and the applet communicate. Perhaps the answer depends on the underlying platform?
Can anyone give me a clue as to why this markup works fine in Safari, but not in Firefox?This should load an ugly blue placeholder (which I get in safari) but in Firefox, swfobject just gives me the alternative content.[code]
I have a media player, which rotates images for the artist it plays. I load the images dynamically into the flash. The flash downloads the same images from the server over and over, how can i cache the images, so flash grabs them from a local cache and not from the server?
I want to put one audio player in my website. For that I need to know if user's browser have flash player installed. Otherwise I will use different player to play audio file(.wav).
I will be glad to know its solution by either javascript or coldfusion.
Most 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?
I'm using Adobe Flash CS4I'm currently trying to fit a flash intro inside the browser window (height 100%, width 100%). I've tried changing the height, width attributes but with no luck. What am I doing wrong?
i have created a silverlight application , but i need to embed it to a Flash file(swf) which it runs with Flash Player ( whithout using browser), I had found a solutions to call it using javascript, but it still needs my flash file run inside the browser, dose any one can help me, Either to run js inside swf (without need of browser) or any other way that i can embed my Silverlight application inside Flash.
I came across a website recently that outputs a whole bunch of user info: IP, browser, OS, flash version, javascript, etc in a very easy to use format. It was specifically designed for remote support, in order to determine user operating environment. However, I cant recall the name of the website.
I have a 100% width and height flash object in my site. Activating and exiting browser full screen mode with F11 only works as long the user didn't click the Flash movie. And I doubt many users know they have to click the address bar to enable F11 after using a (browser) full screen Flash movie.
I am working on a Flash app that is 900x700 pixels. When viewed in misc. browsers at 1024x768, the browser chrome causes robs too much of the vertical space and the app appears in a window with a vertical scrollbar. Unacceptable.
The flash app will be launched via a link emailed to the viewers.
I'd like to avoid resizing the flash app and am wondering if there's a way to do the following via javascript, with no clicks involved:maximize the current browser window remove current window address bar and tabs / switch browser to full screen view (equivalent to pressing F11).
An alternative would be to resize the flash app vertically to match the browser canvas height to avoid scrolling. This may cause the app to become unreadable, so not the best approach in my case.
UPDATE: Seems that browser resizing and autoswitch to full screen won't work and neither will the flash app auto resize. What is the best approach then? And, some users may have browsers with toolbars or open a small browser window.
The only idea I have is to use javascript and display a message to users with small browser windows to pres F11 manually. The audience is executes and some may not even know what an F11 means...
What's the correct way to track mouse position, from Adobe Flash, when someone has: Started a drag within the Flash application (a MOUSE_DOWN event), Dragged the mouse outside the app or even the browser window (a MOUSE_MOVE event), and Released the mouse button (a MOUSE_UP event)? For example (imagine Stack Overflow is a Flash application):
Within the app, I'm able to track the mouse X and Y positions with a MOUSE_MOVE event listener, but I lose it when it goes outside of the browser... So, how do I track the position of the mouse no matter where it goes? For a good example, try Google Finance. Try dragging the chart around; it'll still drag around if you move your mouse out of the browser window, and the mouse will be outside of the browser when you release it.
Also, check out KOKO KAKA; If you click on the scrollbar (make the browser window really small) and move outside of the browser window, the scroll bar moves just like a real one would. I believe both only work because the MOUSE_DOWN event "captures" the mouse, allowing the Flash application to track the position of the mouse even when it is outside of the browser.
I have made an image upload manager. I made it initially in Flash Develop as an AS class. I need to convert it to a component in Flash Builder 4.5 It works absolutely fine as a .swf, but I can't figure out how to make the URL request work in Flash Builder. This is what I have between the tags:[code]I didn't put the mxml controls but there is a browse button (id="selects_btn") and a label (id="label_txt") under the button that displays various status messages.I tried adding the init function to the component's creationComplete event. I receive and error saying access of a null object.
I'd like to gain read only access to the following parameters of embedded Flash videos located on sites that I do not own through my own custom browser extension/add-on:
Time location of playback head (so I can display the current time in the browser extension via HTML5/JavaScript) Frames (so I can make capture them to an image file, save it and display image in browser extension) Original Dimensions in pixels (so I can display the original video dimensions via JS/HTML5 in browser extension)
Is this possible by using Javascript and HTML5 from a browser extension?
Would I have to use something like the SWFObject Javascript API [URL]
I implemented a kind of Bio metric login in Flash. Now, my flash is detecting person and authentication him. But all I need if after bio metric authentication some information to be passed from Flash to my ASP.NET as to initialize session. Is it possible to pass authentication code from Flash file to ASP.NET page?
I have an applicon that needs to render about 100 flash graphs (as well as other DOM stuff) in a series of rows that vertically extend many times beyond the current visible window - in other words, the users have to scroll down see see all the different graphs.This application is also dynamic and when a user changes a value in the DOM (anywhere on the page) it will need to propagate that change to all the Flash graphs at the same time.So I setup all the externalInterface callbacks and was careful to not let any JS start going until the ever-so-important "flashIsReady" call and...it worked great until I tried to update() the existing swf's with new data.
Here was the behavior:- All the swfs load (initially) in both IE/Fox = good.- Updating swfs with new content works in Fox --ONLY IF-- I scrolled down to the bottom of the page, then back to the top -- BEFORE -- I triggered an update().So then I started tracing out each time a swf called the JS to say "flash is ready" and I realized, Firfox only renders swfs as they become visible. And To be honest - that's fine and actually, I am pretty sure that IE does this too. But the problem is that not only does Firefox not initialize the swf, Firefox doesn't even acknowledge the swf exists (expect for after onload) if it has not yet been visible.
