function flashChecker() {

    var hasFlash = 0; //Is flash
 installed
    var flashVersion = 0; //Flash version 

    var isIE =0; //Internet explorer 

    if (isIE) {

        var swf = new ActiveXObject('ShockwaveFlash.ShockwaveFlash');

        if (swf) {

            hasFlash = 1;

            flashVersion = swf.GetVariable("$version");

        }

    } else {

        if (navigator.plugins && navigator.plugins.length > 0) {

            var swf = navigator.plugins["Shockwave Flash"];

            if (swf) {

                hasFlash = 1;

                flashVersion = swf.description.split(" ");

            }

        }

    }

    return {

        f: hasFlash,

        v: flashVersion

    };

}

 

var fls = flashChecker();

if (fls.f) document.write(" You install the flash, The current flash Version for : " + fls.v + ".x");

else document.write(" You did not install flash");

function getFlashVersion() {

     var flashVer = NaN;

     var ua = navigator.userAgent;

 

     if (window.ActiveXObject) {

         var swf = new ActiveXObject('ShockwaveFlash.ShockwaveFlash');

 

         if (swf) {

             flashVer = Number(swf.GetVariable('$version').split(' ')[1].replace(/,/g, '.').replace(/^(d+.d+).*$/, "$1"));

         }

     } else {

         if (navigator.plugins && navigator.plugins.length > 0) {

             var swf = navigator.plugins['Shockwave Flash'];

 

             if (swf) {

                 var arr = swf.description.split(' ');

                 for (var i = 0, len = arr.length; i < len; i++) {

                     var ver = Number(arr[i]);

 

                     if (!isNaN(ver)) {

                         flashVer = ver;

                         break;

                     }

                 }

             }

         }

     }

     return flashVer;

 }

 var flashVer = getFlashVersion();

 if (!isNaN(flashVer)) {

     document.write(' The current flash player  Version: ' + flashVer);   

 } else {

     document.write(' You have not installed flash player ');
