function getNowDate() {
            var myDate = new Date;
            var year = myDate.getFullYear(); //获取当前年
            var mon = myDate.getMonth() + 1; //获取当前月
            var date = myDate.getDate(); //获取当前日
            var hours = myDate.getHours(); //获取当前小时
            var minutes = myDate.getMinutes(); //获取当前分钟
            var seconds = myDate.getSeconds(); //获取当前秒
            var now = year + "-" + mon + "-" + date + " " + hours + ":" + minutes + ":" + seconds;
            return now
        }
