js部分

// appointmentTime是  ‘2020-04-03 18:00’这种字符串形式

  data() {
    return {
      oldAppointTime: new Date(this.itemData.appointmentTime).getTime(),
    }
  },
    

    onConfirmTime(time) {
      this.custFlowInfo.newAppointTime = formatDateHourMinute(time);
      if (this.oldAppointTime > new Date(time).getTime()) {
        this.custFlowInfo.newAppointTime = ''
        Toast.fail('新预约时间应大于原预约时间')
      }
