你大部分都是在这里，你只是错过了测试一部分。不幸的是，没有办法访问给定的属性，告诉你你想要什么。您必须尝试创建对象。

You have most of it right there, you're just missing the testing part of it. Unfortunately there isn't really a way to access a given property that tells you what you want. You have to try to create the object.

function getFlashVersion(){
 var flash = 'None';
 // Count down from 10.
 for(var i = 10; i > 0; i--)
 {
   try{
    flash = new ActiveXObject("ShockwaveFlash.ShockwaveFlash."+String(i));
   }catch(e){
     //console.log(e);
   }
   if(flash != 'None')
    return flash.GetVariable("$version");

 }
 return 0;
}
