Detecting and embedding Flash within a web document is a surprisingly difficult task.

I was very disappointed with the quality and non-standards compliant markup generated from both SWFObject and Adobe's solutions. Additionally, my testing found Adobe's auto updater to be inconsistent and unreliable.

I agree with <a href="https://stackoverflow.com/questions/159261/cross-browser-flash-detection-in-javascript/159374#159374">Max Stewart</a>. <a href="https://github.com/swfobject/swfobject" rel="nofollow noreferrer">SWFObject</a> 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 <code>swfobject.js</code> file (get it <a href="https://github.com/swfobject/swfobject/releases" rel="nofollow noreferrer">here</a>):

<pre><code>&lt;script type="text/javascript" src="swfobject.js"&gt;&lt;/script&gt;
</code></pre>

Then use it like so:

<pre><code>if(swfobject.hasFlashPlayerVersion("9.0.115"))
{
 alert("You have the minimum required flash version (or newer)");
}
else
{
 alert("You do not have the minimum required flash version");
}
</code></pre>

Replace "9.0.115" with whatever minimum flash version you need. I chose 9.0.115 as an example because that's the version that added h.264 support.

If the visitor does not have flash, it will report a flash version of "0.0.0", so if you just want to know if they have flash at all, use:

<pre><code>if(swfobject.hasFlashPlayerVersion("1"))
{
 alert("You have flash!");
}
else
{
 alert("You do not flash :-(");
}
</code></pre>

 return d.join(".")

Does anyone have an example of script that can work reliably well across IE/Firefox to detect if the browser is capable of displaying embedded flash content. I say reliably because I know its not possible 100% of the time.
