This JAVASCRIPT code can be used to detect most of the important browser plugins. They include:

- Flash
- Windows Media Player
- Java
- Shockwave
- RealPlayer
- QuickTime
- Acrobat Reader
- SVG Viewer

Working well in both IE and NS.

Save the following code as plugin.js

//This script detects the following: //Flash //Windows Media Player //Java //Shockwave //RealPlayer //QuickTime //Acrobat Reader //SVG Viewer var agt=navigator.userAgent.toLowerCase(); var ie = (agt.indexOf("msie") != -1); var ns = (navigator.appName.indexOf("Netscape") != -1); var win = ((agt.indexOf("win")!=-1) || (agt.indexOf("32bit")!=-1)); var mac = (agt.indexOf("mac")!=-1); if (ie && win) { pluginlist = detectIE("Adobe.SVGCtl","SVG Viewer") + detectIE("SWCtl.SWCtl.1","Shockwave Director") + detectIE("ShockwaveFlash.ShockwaveFlash.1","Shockwave Flash") + detectIE("rmocx.RealPlayer G2 Control.1","RealPlayer") + detectIE("QuickTimeCheckObject.QuickTimeCheck.1","QuickTime") + detectIE("MediaPlayer.MediaPlayer.1","Windows Media Player") + detectIE("PDF.PdfCtrl.5","Acrobat Reader"); } if (ns || !win) { nse = ""; for (var i=0;i<navigator.mimeTypes.length;i++) nse += navigator.mimeTypes[i].type.toLowerCase(); pluginlist = detectNS("image/svg-xml","SVG Viewer") + detectNS("application/x-director","Shockwave Director") + detectNS("application/x-shockwave-flash","Shockwave Flash") + detectNS("audio/x-pn-realaudio-plugin","RealPlayer") + detectNS("video/quicktime","QuickTime") + detectNS("application/x-mplayer2","Windows Media Player") + detectNS("application/pdf","Acrobat Reader"); } function detectIE(ClassID,name) { result = false; document.write('<SCRIPT LANGUAGE=VBScript>\n on error resume next \n result = IsObject(CreateObject("' + ClassID + '"))</SCRIPT>\n'); if (result) return name+','; else return ''; } function detectNS(ClassID,name) { n = ""; if (nse.indexOf(ClassID) != -1) if (navigator.mimeTypes[ClassID].enabledPlugin != null) n = name+","; return n; } pluginlist += navigator.javaEnabled() ? "Java," : ""; if (pluginlist.length > 0) pluginlist = pluginlist.substring(0,pluginlist.length-1); //SAMPLE USAGE- detect "Flash" //if (pluginlist.indexOf("Flash")!=-1) //document.write("You have flash installed")

You may use the plugin.js as the following to where you need it. Following is an example usage of how to detect Flash installation.
