moment获取上周7天的日期

      const startDate = moment().week(moment().week() - 1).startOf('week').format('YYYYMMDD')
      that.dateArr2 = []
      that.dateArr2.push(moment(startDate).subtract(0, 'days').format('YYYYMMDD'))
      that.dateArr2.push(moment(startDate).subtract(-1, 'days').format('YYYYMMDD'))

      console.log(that.dateArr2)
