Today, I studied a bit of Flex technology and did a small Demo. During the test, I found frequent errors. When I checked online, I found that it was caused by the low version of the browser Flash Player (10 or more versions are needed).

hasFlashPlayer=1; 
flashPlayerVersion=parseInt(shockWaveFlash.GetVariable("$version").split(" ")[1].split(",")[0]);

var shockWaveFlash=navigator.plugins["Shockwave Flash"]; 
if (shockWaveFlash){ 
hasFlashPlayer=1; 
var descriptionInfo = shockWaveFlash.description.split(" "); 
for (var i = 0; i < descriptionInfo.length; ++i){

flashPlayerVersion = parseInt(descriptionInfo[i]);

return {hasFlashPlayer:hasFlashPlayer, flashPlayerVersion:flashPlayerVersion}; 
} 

if(checkFlashPlayer().hasFlashPlayer){ 
if(checkFlashPlayer().flashPlayerVersion <= 10){ 
if(confirm(" your Flash Player Version is too low, upgrade immediately Flash Player Version? ")){
