JavaScript and Flash detection

[Mika S.]

Hi,

How can I detect if the Flash plugin is installed? Should be working
with the most common browsers and environments.

Thanks,
Mika

A good piece of code is available at
http://www.dithered.com/javascript/f...ect/index.html, works well
for all current browsers if you modify the call like this:

<script language="Javas cript" type="text/javascript">
//<![CDATA[
function getFlashVersion () { return null; };
//]]>
</script>
<script language="Javas cript" type="text/javascript"
src="flash_dete ct.js">
</script>

<script type="text/javascript">
var flashEnabled = confirm('Click OK if you have Flash, click Cancel if you do
not have the Flash plugin');
if (flashEnabled)
{alert('Wow, you have Flash!')}
else
{alert('OOOps, No Flash installed')}
</script>

Anything else you try will have flaws. Even the above has flaws. How do you use
javascript to detect flash is javascript is disabled?

Thanks for that, Randy. A very good point.

See http://www.dithered.com/javascript/index.html: "This is a collection
of scripts that I've created and/or modified. Do whatever you want with
them. All I ask is that any comments in the code remain as is"

I suspect that Flash plugin detection will work more reliably than asking users
whether or not they have Flash installed ("Do I have what installed?") If
Javascript is not available falling back to the plain, non-Flash version is usually
a reasonable alternative.

<script type="text/javascript">
if (goodFlashVersi on) {
document.write( '<!-- put flash stuff here -->');
}
else {
document.write( '<!-- put plain version here -->');
}
</script>
<noscript>
<!-- put plain version here -->
</noscript>
