JavaScript判断浏览器Flash Player信息

        今天研究了点Flex技术,做了一个小的Demo,在测试时发现经常报错,网上一查发现是浏览器Flash Player版本较低造成(需要10及其以上的版本)的,对此总结了一下借助JavaScript脚本判断浏览器Flash Player信息的方法:

		<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?")){
