JavaScriptでFlashのバージョンを取得

既存のソースでFlashのバージョン取得を

行っているものがあり、使いそうなのでメモ。

var flashVer = (function() {
if (navigator.plugins && navigator.mimeTypes['application/x-shockwave-flash']) {
var plugin = navigator.mimeTypes['application/x-shockwave-flash'].enabledPlugin;
if (plugin && plugin.description) {
var ver = plugin.description.replace(/^[A-Za-z\s]+/,'').replace(/(\s+r|\s+b[0-9]+)/,".");
}
} else {
var x='';
try {
var axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.7");
x=axo.GetVariable("$version");
} catch(e) {
try {
axo=new ActiveXObject("ShockwaveFlash.ShockwaveFlash.6");
x = "WIN 6,0,21,0";
axo.AllowScriptAccess = "always";
x = axo.GetVariable("$version");
} catch(e) {
if (!x.match(/^WIN/)) {
try {
axo = null;
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.3");
x = axo.GetVariable("$version");
} catch(e) {
if (axo){
x = "WIN 3,0,18,0";
} else {
try {
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash");
x = "WIN 2,0,0,11";
} catch(e) {
x = "WIN 0,0,0,0";
}
}
}
}
}
}
ver = x.replace(/^WIN /,'').replace(/,[0-9]+$/,'').replace(/,/g,'.');
}
return (ver == '0.0.0') ? false : ver;
}());
