        var date = myDate.getDate();
        var h = myDate.getHours();       //获取当前小时数(0-23)
        var m = myDate.getMinutes();     //获取当前分钟数(0-59)
        if (m < 10) m = '0' + m;
        var s = myDate.getSeconds();
        if (s < 10) s = '0' + s;
        var nowtime = year + '-' + month + "-" + date;
