Detect Flash Player

[kaos]

So,

I got this flash detection kit form Adobe. It's almost perfect but what it currently does is display and alert every time showing your flash version. I only want it t display if they don't have the latest version. heres the code:


var isIE = (navigator.appVersion.indexOf("MSIE") != -1) ? true : false;
var isWin = (navigator.appVersion.toLowerCase().indexOf("win") != -1) ? true : false;
var isOpera = (navigator.userAgent.indexOf("Opera") != -1) ? true : false;
function ControlVersion()
{
var version;
var axo;
var e;
try {
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.7");
version = axo.GetVariable("$version");
} catch (e) {
}

if (!version)
{
try {
// version will be set for 6.X players only
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.6");

// installed player is some revision of 6.0
// GetVariable("$version") crashes for versions 6.0.22 through 6.0.29,
// so we have to be careful.

// default to the first public version
version = "WIN 6,0,21,0";

// throws if AllowScripAccess does not exist (introduced in 6.0r47)
axo.AllowScriptAccess = "always";

// safe to call for 6.0r47 or greater
version = axo.GetVariable("$version");

} catch (e) {
}
}

if (!version)
{
try {
// version will be set for 4.X or 5.X player
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.3");
version = axo.GetVariable("$version");
} catch (e) {
}
}

if (!version)
{
try {
// version will be set for 3.X player
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.3");
version = "WIN 3,0,18,0";
} catch (e) {
}
}

if (!version)
{
try {
// version will be set for 2.X player
axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash");
version = "WIN 2,0,0,11";
} catch (e) {
version = -1;
}
}

return version;
}

// JavaScript helper required to detect Flash Player PlugIn version information
function GetSwfVer(){
// NS/Opera version >= 3 check for Flash plugin in plugin array
var flashVer = -1;

if (navigator.plugins != null && navigator.plugins.length > 0) {
if (navigator.plugins["Shockwave Flash 2.0"] || navigator.plugins["Shockwave Flash"]) {
var swVer2 = navigator.plugins["Shockwave Flash 2.0"] ? " 2.0" : "";
var flashDescription = navigator.plugins["Shockwave Flash" + swVer2].description;
var descArray = flashDescription.split(" ");
var tempArrayMajor = descArray[2].split(".");
var versionMajor = tempArrayMajor[0];
var versionMinor = tempArrayMajor[1];
var versionRevision = descArray[3];
if (versionRevision == "") {
versionRevision = descArray[4];
}
if (versionRevision[0] == "d") {
versionRevision = versionRevision.substring(1);
} else if (versionRevision[0] == "r") {
versionRevision = versionRevision.substring(1);
if (versionRevision.indexOf("d") > 0) {
versionRevision = versionRevision.substring(0, versionRevision.indexOf("d"));
}
}
var flashVer = versionMajor + "." + versionMinor + "." + versionRevision;
//alert("flashVer="+flashVer);
}
}
// MSN/WebTV 2.6 supports Flash 4
else if (navigator.userAgent.toLowerCase().indexOf("webtv/2.6") != -1) flashVer = 4;
// WebTV 2.5 supports Flash 3
else if (navigator.userAgent.toLowerCase().indexOf("webtv/2.5") != -1) flashVer = 3;
// older WebTV supports Flash 2
else if (navigator.userAgent.toLowerCase().indexOf("webtv") != -1) flashVer = 2;
else if ( isIE && isWin && !isOpera ) {
flashVer = ControlVersion();//alert("control version="+flashVer);
}
return flashVer;
}

You should try swfobject (http://code.google.com/p/swfobject/) instead. AFAIK, it is the industry standard for Flash detection and implementation. Check out this page:
