flash检测方法
//IE下获取flash版本号，如果flash插件不存在则返回-1function ControlVersion(){ var version; var axo; var e; try { axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.7"); version = axo.GetVariable("$version"); } catch (e) { } if (!version) { try { axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.6"); version = "WIN 6,0,21,0"; axo.; version = axo.GetVariable("$version"); } catch (e) { } } if (!version) { try { axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.3"); version = axo.GetVariable("$version"); } catch (e) { } } if (!version) { try { axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash.3"); version = "WIN 3,0,18,0"; } catch (e) { } } if (!version) { try { axo = new ActiveXObject("ShockwaveFlash.ShockwaveFlash"); version = "WIN 2,0,0,11"; } catch (e) { version = -1; } } var verArr = version.toString().split(','); var str = ''; for(var i=0,l=verArr.length;i<l;i++){ if(verArr.indexOf('WIN') != -1){ str += verArr.substring(3); str += '.'; }else if(i== (l-1)){ str += verArr; }else{ str += verArr; str += '.'; } } return (str);}//判断function flashChecker(){ var hasFlash=0; //是否安装了flash var flashVersion=0; //flash版本 var isIE=0; //是否IE浏览器 if(isIE) { var swf = ControlVersion(); if(swf != -1) { hasFlash=1; flashVersion = swf; } }else{ if (navigator.plugins && navigator.plugins.length > 0) { if (navigator.plugins["Shockwave Flash 2.0"] || navigator.plugins["Shockwave Flash"]) { hasFlash=1; var swVer2 = navigator.plugins["Shockwave Flash 2.0"] ?
