If swfobject won’t suffice, or you need to create something a little more bespoke, try this: var hasFlash = false; try { hasFlash = Boolean(new ActiveXObject(‘ShockwaveFlash.ShockwaveFlash’)); } catch(exception) { hasFlash = (‘undefined’ != typeof navigator.mimeTypes[‘application/x-shockwave-flash’]); } It works with 7 and 8.
Usually ‘lost’ is a euphemism for “We stopped paying the developer and now he wont give us the source code.” That being said, I own a copy of Burak’s ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.
Mega uses several different methods to do this: (as of 27 Nov 2013) Filesystem API (Chrome/Firefox Extension polyfill) Adobe Flash SWF Filewriter (old browsers fallback) BlobBuilder (IE10/IE11) MEGA Firefox Extension (deprecated) Arraybuffer/Blob (in memory) + a[download] (for browsers that support a[download]) MediaSource (experimental streaming solution) Blob stored in IndexedDB storage + a[download] (Firefox 20+, improvement … Read more
I agree with Max Stewart. SWFObject is the way to go. I’d like to supplement his answer with a code example. This ought to to get you started: Make sure you have included the swfobject.js file (get it here): <script type=”text/javascript” src=”https://stackoverflow.com/questions/159261/swfobject.js”></script> Then use it like so: if(swfobject.hasFlashPlayerVersion(“9.0.115”)) { alert(“You have the minimum required flash … Read more
This can be done through the youtube player API: http://jsfiddle.net/7Gznb/ Working example: <div id=”player”></div> <script src=”http://www.youtube.com/player_api”></script> <script> // create youtube player var player; function onYouTubePlayerAPIReady() { player = new YT.Player(‘player’, { width: ‘640’, height: ‘390’, videoId: ‘0Bmhjf0rKe8’, events: { onReady: onPlayerReady, onStateChange: onPlayerStateChange } }); } // autoplay video function onPlayerReady(event) { event.target.playVideo(); } // … Read more
Imagine if there was no img tag. If you want images, you have to use a 3rd party plugin, that is really slow and has no standard way to embed it in a page. You can’t easily copy images in this way, and search engines basically have no clue what if it’s an image or … Read more

What people loosely refer to HTML5 in the context of this discussion is the combination of HTML as a markup language, CSS which specifies how it is rendered, and the javascript code which manipulates the HTML and CSS dynamically. Furthermore, HTML5 not only has the standard text elements, but also <canvas> on which 2d graphics … Read more
The best approach to embed a SWF into an HTML page is to use SWFObject. It is a simple open-source JavaScript library that is easy-to-use and standards-friendly method to embed Flash content. It also offers Flash player version detection. If the user does not have the version of Flash required or has JavaScript disabled, they … Read more
The proper way is to look at the HTTP Accept-Language header sent to the server. This contains the ordered, weighted list of languages the user has configured their browser to prefer. Unfortunately this header is not available for reading inside JavaScript; all you get is navigator.language, which tells you what localised version of the web … Read more
