有數(shù)據(jù)區(qū)間

[{"startPeriod":"09:00","endPeriod":"20:00"},
{"startPeriod":"10:01","endPeriod":"16:00"}]

判斷是否 有 重復(fù)的

isHasRepeatTime(data) {
      const startTimeArr = []
      const endTimeArr = [];
      (data || []).map(function(item) {
        startTimeArr.push(item.startPeriod)
        endTimeArr.push(item.endPeriod)
      })
      const allStartTime = startTimeArr.sort()
      const allEndTime = endTimeArr.sort()
      let result = 0
      for (let k = 1; k < allStartTime.length; k++) {
        if (allStartTime[k] < allEndTime[k - 1]) {
          result += 1
        }
      }
      return result > 0
    }
