        var ts = (new Date(2018, 11, 11, 9, 0, 0)) - (new Date());//计算剩余的毫秒数  
        console.log(ts);  
        var dd = parseInt(ts / 1000 / 60 / 60 / 24, 10);//计算剩余的天数  
        var hh = parseInt(ts / 1000 / 60 / 60 % 24, 10);//计算剩余的小时数  
        var mm = parseInt(ts / 1000 / 60 % 60, 10);//计算剩余的分钟数  
        var ss = parseInt(ts / 1000 % 60, 10);//计算剩余的秒数  
        document.getElementById("timer").innerHTML = dd + "天" + hh + "时" + mm + "分" + ss + "秒";  
    }  
    setInterval(timer,1000);
