日期和时间

1.获取当前日期

//获取当前时间，格式为：2021-09-06 12:22:09 
      getNowTime() {
        Date.prototype.Format = function (fmt) {
          var o = {
            "M+": this.getMonth() + 1, //月份
            "d+": this.getDate(), //日
            "H+": this.getHours(), //小时
            "m+": this.getMinutes(), //分
            "s+": this.getSeconds(), //秒
            "q+": Math.floor((this.getMonth() + 3) / 3), //季度
            "S": this.getMilliseconds() //毫秒
          };
          if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
          for (var k in o)
            if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
          return fmt;
        }
        var datetime = new Date().Format("yyyy-MM-dd HH:mm:ss");
        return datetime;

      },
