Cross Browser Flash Detection in Javascript

Question

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.

Answer 1

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="swfobject.js"></script>

Then use it like so:

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");
}

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:

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