Javascript swfobject未定义错误

我正在尝试检测flash支持，我正在尝试按照以下回答进行操作：

我的代码如下，但我总是得到相同的错误：swfobject未定义。我不应该这样做，因为我正在支持flash（chrome和firefox）的浏览器中尝试

---

这是最新浏览器的问题吗？是否有其他方法检测它？

尝试检查

对象的
类型，如下所示：

if(typeof swfobject != "undefined"){ //Check if type of the object is undefined

    console.log("you have swfobject.");

    if(swfobject.hasFlashPlayerVersion("1")){
        console.log("You have flash!");
    }
    else{
        console.log("You do not flash :(");
    }
}else{
    console.log("you don't have swfobject");
}

引导我走过一条完全不同的道路：

if(navigator.mimeTypes["application/x-shockwave-flash"]){
    var plugin = navigator.mimeTypes["application/x-shockwave-flash"].enabledPlugin;
    var description = plugin.description;
    var versionArray = description.match(/[\d.]+/g);
    var flashVersionOSXScriptable = 12;
    var flashVersion = parseInt(versionArray[0]);

    if(navigator.userAgent.indexOf("Mach-O")==-1){
        if(flashVersion >= flashVersionOSXScriptable){
            console.log("you have flash");
        }else{
            console.log("you don't have flash");
        }
    }

    console.log("you don't have flash");
