Flash detection Javascript doesn't work in Firefox

C

Cliff R.

Hi, I use a handy little Javascript Flash detection script on a number
of sites (copied below). Usually works great, but I just started
trying Firefox and it's not working. A few browsers are referenced in
the script so I presume that Firefox needs to be added somewhere --
does anyone know how I could update this to be supported by Firefox?
Thanks!



<SCRIPT TYPE="text/JavaScript">
<!--
var MM_contentVersion = 5;
var plugin = (navigator.mimeTypes &&
navigator.mimeTypes["application/x-shockwave-flash"]) ?
navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin :
0;
if ( plugin ) {
var words = navigator.plugins["Shockwave
Flash"].description.split(" ");
for (var i = 0; i < words.length; ++i)
{
if (isNaN(parseInt(words)))
continue;
var MM_PluginVersion = words;
}
var MM_FlashCanPlay = MM_PluginVersion >= MM_contentVersion;
}
else if (navigator.userAgent && navigator.userAgent.indexOf("MSIE")>=0
&& (navigator.appVersion.indexOf("Win") != -1)) {
document.write('<SCR' + 'IPT LANGUAGE=VBScript\> \n'); //FS
hide this from IE4.5 Mac by splitting the tag
document.write('on error resume next \n');
document.write('MM_FlashCanPlay = (
IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash." &
MM_contentVersion)))\n');
document.write('</SCR' + 'IPT\> \n');
}
if ( MM_FlashCanPlay ) {

That part of the script is the part to check Netscape or other browsers
like Firefox having the navigator.mimeTypes collection so that script
works with Firefox, for instance when I run that part here with Firefox
1.0 and Shockwave Flash player 7.something installed the variable
MM_FlashCanPlay is true.
So what exactly happens for you when you say "doesn't work with
Firefox", any script errors?
What does
about:plugins
show, does that show Shockwave Flash for the MIME type
application/x-shockwave-flash?

Hi -- when I said it doesn't work in Firefox, I mean that nothing is
showing where the Flash should be. Not the Flash itself or the image
that's supposed to show if there is no Flash player. And I don't see
any script errors, it's just not showing anything. I'm not sure what
all the elements of the script mean because I didn't write it, but I
do know that it's always worked.

But here's the weird thing, I just noticed that it works on some sites
and not on others (meaning the Flash movie does display). For
example, the same script works on http://www.skyblues.com/ but not on
http://www.bluerill.com/ . Any thoughts or help? Thank you!

I see Flash movies on http://www.bluerill.com/ with Firefox 1.0, I
haven't checked how many the page source includes and whether all are
there but there is Flash visible on the page.

Weird, I have Firefox 1.0 also and I'm just seeing 2 empty blue spaces
where the Flash animations should be (there are 2 animations on that
page). I checked to make sure Javascript is enabled and it is. Any
other thoughts on why this might be?

Thank you for your help!

Not really, other than checking
about:plugins
to see whether Firefox correctly finds the Flash player and the right
version of it.
Then to find out what the problem could be I would start by using static
HTML markup to embed the Flash (e.g. <embed ...>) and see whether that
is rendered by Firefox. Only if it is I would look at the script again
as then it is likely that the script use is the cause of the problem.
