谷歌浏览器默认禁用了flash插件,所以要判断下浏览器是否禁用了flash

function flashJudge(){
      var flag = false;
      if(window.ActiveXObject){
        try{
          var swf = new ActiveXObject("ShockwaveFlash.ShockwaveFlash");
          if(swf){
            flag = true;
          }
        }catch(e){
        }
      }else{
        try{
          var swf = navigator.plugins['Shockwave Flash'];
          if(swf){
            flag = true;
          }
        }catch(e){
        }
      }
      if(flag){
        console.log("running ok");
      }else{
        console.log("running error");
      }
    }
