Recently we have seen a lot of progress with the capabilities of Javascript to leverage the capabilities of HTML to do things that was previously only possible using Flash.
Thanks to for example mootools and jQuery you can now create sites that looks like they are made with Flash with nice tweening animations, and of course AJAX have already for a few years been an option to update the content without reloading the page.
Does this mean that the future of Flash looks bleak?
Somerandomdude seems to think so, and points to some of examples if the impeding demise of Flash. John Resig’s Processing.js and experiments with HTML 5’s video element.


First of all, does any of these developments offer improvements over what Flash have been capable of for years?
Maybe if a site that is heavy on information but you might want to jazz it up a bit with some nice transitions.
When it comes to presenting text HTML has some advantages, mainly due to the browser integration.
Using the browsers built in search or select and right click to google a phrase for example.
Usually those advantages are greater than the possibility to embed font outlines with Flash.
But most implementations I have seen of for example slideshows and menus does not offer any advantages what I can see. Implementing them in Javascript still performs worse, gives you less possibilities and makes it less accessible.


When it comes to video on the surface I cannot see any reason why a video playback native to the browser would be preferable.
Of course one could argue that since you have a limited choice of compression formats with Flash it would open up to more options there. But to deploy content you will still have to make sure you use a codec that is included with a majority of browsers. It remains to be seen if it will mean much of an improvement in practice, and personally I do think that h264 is quite satisfactory.
All the above is true for the HTML5 audio element as well.


Of course the technical merits is only a part of the parameters that decide the acceptance of a technology. There are a lot of developers that really dislike Flash for various reasons and they are just really happy that they now can do the same things as has been possible for a long time with Flash.
The fact that it can be more tedious to implement and performs worse is not as important as various factors like avoiding proprietary formats or using a environment they are already accustomed to.


But even if Flash is not necessary to do a lot of things that previously was it’s exclusive domain to me it seems like it’s constantly gaining acceptance with developers.
Flash is still quite far ahead of the capabilities of DHTML/AJAX and how long will it take before HTML5 is widespread enough to make it a viable option?
Flash is still developing rapidly and the new versions of the plug-in is spreading extremely fast, so by the time HTML5 capable browsers is widespread enough probably 95% will have the Flash 15 plug-in installed.


I think the main issue here is the different ways in which Flash and HTML is being developed.
A lot of the hate against Flash is based on the fact that swf is a proprietary format, and even if that is not entirely true any more it’s certainly not based on an open standard.
And that what makes it possible for it to stay on the cutting edge, and that’s why the capabilities of DHTML, XHTML, Javascript, SVG etc. always is one step behind.
Even if I prefer open standards in theory it just doesn’t seem to work as well in practice.
Rather than being impressed how HTML and Javascript is catching up with the capabilities of Flash I’m continuously surprised at how slowly it’s happening.


I have been fanatic about Flash since I first discovered it in 1999, and I really have trouble being completely neutral even I try. But IMO Flash is not going anywhere. With AS3, AVM2 and FLEX a lot of new possibilities has opened up that DHTML will not be capable of any time soon, like for example decent 3d engines, socket connections and sound synthesis.
Overall I do see a trend though that the web is getting less and less fixated with certain technologies.
On the server side we have seen Python and Ruby gaining acceptance. MS will be trying with Silverlight to present an alternative to Flash and HTML will be able to compete as well.
But it’s not a war where anyone has to die…there is certainly room for more than either ASP, perl or PHP on the server and HTML, Shockwave or Flash on the client, which pretty much used to be the case.

I’m glad to have discovered that someone made an effort making a script similar to my backbutton and deeplinking solution for Flash.
Maybe old news to many of you, but since I get some visitors here looking for such a solution I thought I mention it.

I haven’t got a chance to try it out and only had a look at the info on their web page, but it seems to be a very good alternative to my own script.

I’ve done a little update to my system for enabling the back button and providing deep linking/bookmarking functionality for Flash sites and applications.
It’s now using Macromedias JS integration kit for Flash to JS communication.

Click here to download it.

Try the system here.

I was hoping I would solve issues with some browsers that it was not working with previously, but since there is more issues than if the browser supports the setVariable command to pass data from JS to Flash it seems like it will be very difficult to get a few browser/OS combinations to work.

Basically I found two different methods of approach.

One is using Rober Penners hidden frame method.
That’s still what the system does for IE, but using an iFrame instead instead of a regular frame set and removing the need to create actual HTML files to load into the frame by using document.write().
With FF I did not have much luck with that approach.
Just using JS to write into the hidden frame worked fine and made the back button work, but when trying to also update the hash to enable the bookmarking everything started going wrong.

The other approach is to at regular intervals check the location.hash and if it’s been updated cause a change of state in Flash.

Both approaches have various problems on different browsers.
For example Safari apparently will not record a history event when you use document.write() to update an iFrame.
Opera 8 will not record a history event if you update the hash, and after experimenting a bit with writing into the iFrame I gave up on getting it to work with that method.

It would be great with a system that works for every perceivable browser and OS, but as long as the system fails gracefully it’s at least not doing any harm to implement and as it is now it will cover a vast majority of users.

So far I tested and confirmed it working with FF 1.0.6 and 1.5 beta 1, IE6, NS8 and Opera 8.5
Opera 8.01 does not show the hash and back button fails, but at least deep links are working.

I would be very interested to hear from mac users in particular to find out if NS, Safari and IE still is not working.

I was looking around for some example code for how to implement full state management in Flash with both functioning back/forward buttons and deeplinking/bookmarking, but couldn’t find any.

So I decided to put together my own and make it available in an attempt to silence the many Flash critics who, rightfully in my opinion, think that it is a major drawback with pure Flash sites.

It’s only tested and working with recent versions of firefox and IE on windows.
Backbutton and bookmarking fails with Opera 8, but deeplinking works.
I’m quite sure someone with decent JS skills should be able to fix that though.
The problem is that “document[movieid].SetVariable();” does not target the swf correctly, which is a mystery to me since I have seen examples using the same syntax that does work.
Another solution would be to rewrite the code to use localConnection instead in which case most browsers should have no problem.

But for now at least you can easily have state management functioning for the very large percentage of users that use FF or IE, and other browsers should hopefully all fail gracefully and be able to follow deeplinks in to your flash site.
So there is no excuse to now implement state management into your Flash site now.

You can try the system with this little ugly example
Please leave a comment if you are using a browser other than FF or IE on windows so I can make a list of what browsers it is working on.

Get the download here.

I made a new version using Macromedia JS integration kit for communication between Flash and JS.
Get the download here.
It did not solve the issues with Opera 8.01 apart from getting rid of the JS error, and I doubt that Safari will work still.
So until I get some feedback on how it works with the Browsers that been problematic I’m not sure how much of an improvement it is.
I updated the example above, so try it out and tell me if it’s not working with a particular browser.
So far confirmed to be working is FF 1.0.6 & 1.5 beta1, IE 6, Opera 8.5 and NS8. Not working so far is Opera 8.01
