el-date-picker 結束時間大於等於開始時間，早於今天的時間不可選

配置：

// 判斷兩個時間 結束時間不能大於開始時間
      pickerOptions0: {
        disabledDate: (time) => {
          // let beginDateVal = new Date(this.endtime).getTime()
          // if (beginDateVal) {
          //   return (time.getTime() > beginDateVal) || (time.getTime() > Date.now())
          // } else {
            return time.getTime() < Date.now() - 8.64e7
          // }
        }
      },
      pickerOptions1: {
        disabledDate: (time) => {
          let beginDateVal = new Date(this.form.startTime).getTime()
          if (beginDateVal) { // 等於的時候是臨界值00:00:00
            return (time.getTime()) <= beginDateVal - 8.64e7
          } else {
            return time.getTime() < Date.now() - 8.64e7 
          }
        }
      }

效果：
