復(fù)制代碼代碼如下:

function getFlashVersion() {

     var flashVer = NaN;

     var ua = navigator.userAgent;

     if (window.ActiveXObject) {

         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('當(dāng)前flash player 的版本：' + flashVer);   

 } else {

     document.write('您尚未安裝flash播放器');
