How to check with JS if flash is installed, or not? I don't want to detect the version, or other informations. I want to check only, if it's avaiable, or not.

The swfobject library makes it (and many other things, which are unneccessary for that), but I don't want to use a library for only one function.

If you’re using Flash to progressively enhance a document, please use this script to feature detect it first.

var hasFlash = ((typeof navigator.plugins != "undefined" && typeof navigator.plugins["Shockwave Flash"] == "object") || (window.ActiveXObject && (new ActiveXObject("ShockwaveFlash.ShockwaveFlash")) != false));

hasFlash will be true if Flash is available, or falsy if it isn’t.

If you already have access to the Flash element you want to use then you could just do:

var hasFlash = 'Pan' in element;

You can check if Flash is installed (see Mathias answer) but be aware that even if Flash is installed is still may be disabled (see here for examples http://blog.lroot./articles/techniques-to-easily-disable-flash-in-firefox-and-ie/) so your movies won't play at all.
