日程表-獲取當前周，點選切換上一週和下一週

獲取本週的開始日期和結束日期（本週週一到週日）：

var currentTime = new Date()

this.getThisWeekData(currentTime, 0)

點選切換上週的周曆(把當前周的週一的時間傳進去就行，如“2024-08-05”)：

this.getThisWeekData(currentData.startData, -7)

點選切換下週的周曆(把當前周的週一的時間傳進去就行，如“2024-08-05”)：

this.getThisWeekData(currentData.startData, 7)

getThisWeekData(time, OptType) {
      //optType 0:本週 -7:上週 7:下週
      var date = new Date(time)
      if (OptType === 0) {
        var tempStartData = date.setDate(date.getDate() - date.getDay() + 1)
        var startData = this.getTimeStyle(tempStartData)
        console.log('本週一', startData)
      } 
      else if (OptType === -7){
        var tempStartData = date.setDate(date.getDate() - date.getDay() -6)
        var startData = this.getTimeStyle(tempStartData)
        console.log('上週一', startData)
      }
      else if (OptType === 7) {
        var tempStartData = date.setDate(date.getDate() - date.getDay() +8)
        var startData = this.getTimeStyle(tempStartData)
        console.log('下週一', startData)
      } 
      var tempEndData = date.setDate(date.getDate() + 6)
      var endData = this.getTimeStyle(tempEndData)
      console.log('週日', endData)

      this.currentData = {
        startData: startData,
        endData: endData
      }
    },
