Today I studied some Flex technology and made a small demo. During the test, I found that errors were often reported. I checked online and found that it was caused by a lower version of the browser Flash Player (requires version 10 and above). Regarding this Here’s a summary of how to use JavaScript scripts to determine browser Flash Player information:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
<title>JavaScript判断浏览器Flash Player信息</title> 
<meta http-equiv="content-type" content="text/html; charset=UTF-8"> 
<script type="text/javascript"> 
function checkFlashPlayer(){ 
var hasFlashPlayer=0; //判断是否安装了Flash Player 
var flashPlayerVersion=0; //Flash Player版本 
if(document.all){ 
var shockWaveFlash = new ActiveXObject('ShockwaveFlash.ShockwaveFlash'); 
if(shockWaveFlash) { 
hasFlashPlayer=1; 
flashPlayerVersion=parseInt(shockWaveFlash.GetVariable("$version").split(" ")[1].split(",")[0]); 
} 
}else if (navigator.plugins && navigator.plugins.length > 0){ 
var shockWaveFlash=navigator.plugins["Shockwave Flash"]; 
if (shockWaveFlash){ 
hasFlashPlayer=1; 
var descriptionInfo = shockWaveFlash.description.split(" "); 
for (var i = 0; i < descriptionInfo.length; ++i){ 
if (isNaN(parseInt(descriptionInfo[i]))){ 
continue; 
} 
flashPlayerVersion = parseInt(descriptionInfo[i]); 
} 
} 
} 
return {hasFlashPlayer:hasFlashPlayer, flashPlayerVersion:flashPlayerVersion}; 
} 

if(checkFlashPlayer().hasFlashPlayer){ 
if(checkFlashPlayer().flashPlayerVersion <= 10){ 
if(confirm("您的Flash Player版本过低，立即升级Flash Player版本？")){ 
window.location.href="http://get.adobe.com/cn/flashplayer/" rel="external nofollow" rel="external nofollow" ; 
} 
}else{ 
alert("您安装了Flash Player，当前Flash Player版本号为："+checkFlashPlayer().flashPlayerVersion+"。"); 
} 
}else{ 
if(confirm("您没有安装Flash Player，立即安装？")){ 
window.location.href="http://get.adobe.com/cn/flashplayer/" rel="external nofollow" rel="external nofollow" ; 
} 
}
