前段时间根据需求处理一个时间筛选组件,如图

主要工作在于两点:

  1. 时间快选处理
  2. 开始时间和结束时间的可选范围处理

时间快选:

主要是获取到当前按钮的日期范围,全部代码如下所示

  1 const getTimeRange = (startTime, endTime, xFormat) => { // 可选的开始时间,可选的结束时间,格式
  2   let sT = new Date(startTime)
  3   let eT = new Date(endTime)
  4   let today = new Date()
  5   let nowMonth = today.getMonth() // 当前月
  6   let format = xFormat || ‘YYYY-MM-DD‘
  7   const dayMSec = 24 * 3600 * 1000
  8   // 昨天
  9   let _yesterdayMSec = today.getTime() - dayMSec
 10   let yesterday = new Date(_yesterdayMSec)
 11   // 本月第一天
 12    let nowMonthFirstDay = new Date(today.getFullYear(), today.getMonth(), 1)
 13   // 上一个月的第一天
 14   let lastMonthFirstDay = new Date(today.getFullYear(), today.getMonth() - 1, 1)
 15   let _lastMonthLastDayMSec = nowMonthFirstDay.getTime() - dayMSec
 16   // 上一个月的最后一天
 17   let lastMonthLastDay = new Date(_lastMonthLastDayMSec) // 上月最后一天
 18   // 本年第一天
 19    let nowYearFirstDay = new Date(today.getFullYear(), 0, 1)
 20   // 去年第一天
 21   let lastYearFirstDay = new Date(today.getFullYear() - 1, 0, 1)
 22   // 去年最后一天
 23   let _lastYearlastDaySec = nowYearFirstDay.getTime() - dayMSec
 24   let lastYearlastDay = new Date(_lastYearlastDaySec)
 25   // 获取本季度开始月份
 26   let quarterStartMonth = 0
 27   let last_s_quarter_y = today.getFullYear()
 28   let last_s_quarter_m = 0
 29   if (nowMonth < 3) {
 30     quarterStartMonth = 0
 31     last_s_quarter_y = today.getFullYear() - 1
 32     last_s_quarter_m = 9
 33   }
 34   if (nowMonth > 2 && nowMonth < 6) {
 35     quarterStartMonth = 3
 36     last_s_quarter_m = 0
 37   }
 38   if (nowMonth > 5 && nowMonth < 9) {
 39     quarterStartMonth = 6
 40     last_s_quarter_m = 3
 41   }
 42    if (nowMonth > 8) {
 43     quarterStartMonth = 9
 44     last_s_quarter_m = 6
 45   }
 46   // 本季度第一天
 47    let quarterStartDate = new Date(today.getFullYear(), quarterStartMonth, 1)
 48   // 上季度第一天
 49   let last_quarterStartDate = new Date(last_s_quarter_y, last_s_quarter_m, 1)
 50   let _last_quarterEndDateSec = quarterStartDate.getTime() - dayMSec
 51   let last_quarterEndDate = new Date(_last_quarterEndDateSec)
 52   // 格式化日期:默认yyyy-MM-dd
 53   function formatDate (date) {
 54     let myyear = date.getFullYear()
 55     let mymonth = date.getMonth() + 1
 56     let myweekday = date.getDate()
 57     if (mymonth < 10) {
 58       mymonth = ‘0‘ + mymonth
 59     }
 60     if (myweekday < 10) {
 61       myweekday = ‘0‘ + myweekday
 62     }
 63    let formatObj = {
 64       ‘YYYY-MM-DD‘: (myyear + ‘-‘ + mymonth + ‘-‘ + myweekday),
 65       ‘YYYY-MM‘: (myyear + ‘-‘ + mymonth),
 66       ‘YYYY‘: (myyear)
 67     }
 68    return formatObj[format]
 69   }
 70    function getRes (begin, after) {
 71     let ST = begin
 72     let ET = after
 73     if (startTime && endTime) {
 74       if (begin.getTime() < sT.getTime()) {
 75         ST = sT
 76       }
 77   if (after.getTime() > eT.getTime()) {
 78         ET = eT
 79       }
 80     }
 81     return [formatDate(ST), formatDate(ET)]
 82   }
 83   // 获取前几个月
 84   function getRes1 (after, number) {
 85     let ET = after
 86     if (endTime) {
 87       if (after.getTime() > eT.getTime()) {
 88         ET = eT
 89       }
 90     }
 91   let before = new Date(ET.getFullYear(), ET.getMonth() - number)
 92     let ST = before
 93     if (startTime) {
 94       if (before.getTime() < sT.getTime()) {
 95         ST = sT
 96       }
 97     }
 98     return [formatDate(ST), formatDate(ET)]
 99   }
100   return {
101     aYear: getRes1(today, 12), // 前十二个月
102     lastYear: getRes(lastYearFirstDay, lastYearlastDay), // 去年
103     nowYear: getRes(nowYearFirstDay, today), // 今年
104     lastQuarter: getRes(last_quarterStartDate, last_quarterEndDate), // 上季度
105     nowQuarter: getRes(quarterStartDate, today), // 本季度
106     lastMonth: getRes(lastMonthFirstDay, lastMonthLastDay), // 上月
107     nowMonth: getRes(nowMonthFirstDay, today), // 本月
108     yesterday: getRes(yesterday, yesterday), // 昨日
109     today: getRes(today, today) // 本日
110   }
111 }

获取到日期后判断是否需要显示

 timeQuickArrDef: [
          {name: ‘本日‘, value: ‘today‘, show: true, len: 3},
          {name: ‘昨日‘, value: ‘yesterday‘, show: true, len: 3},
          {name: ‘本月‘, value: ‘nowMonth‘, show: true, len: 2},
          {name: ‘上月‘, value: ‘lastMonth‘, show: true, len: 2},
          {name: ‘本季度‘, value: ‘nowQuarter‘, show: true, len: 2},
          {name: ‘上季度‘, value: ‘lastQuarter‘, show: true, len: 2},
          {name: ‘本年‘, value: ‘nowYear‘, show: true, len: 1},
          {name: ‘去年‘, value: ‘lastYear‘, show: true, len: 1}
        ],

// 获取可显示的时间快选框
 getTimeQuickArr () {
        let _this = this
        let len = _this.xFormat.split(‘-‘).length
        _this.textTag = _this.textArr[len]
        _this.timeQuickArr = []
        _this.timeQuickArrDef.map(item => {
          item.len <= len && _this.timeQuickArr.push(item)
        })
      },
// 根据可选时间范围确定时间快选按钮是否可点击
      ifShow_timeQuickArr () {
        let _this = this
        _this.timeQuickArrLen = _this.timeQuickArr.length
        _this.timeQuickArr.map(item => {
          let bT = _this.timeRangeObj[item.value][0]
          let aT = _this.timeRangeObj[item.value][1]
          if (_this.timeToNum(aT) < _this.timeToNum(bT)) {
            item.show = false
            _this.timeQuickArrLen--
          }
        })
      },

开始时间和结束时间的可选范围处理

思路:初始时间根据传入组件的开始和结束时间来约束开始结束时间

选择开始或者结束时间后重新计算另一个时间框的结束与开始时间

 1  timeOpen (tag, value) {
 2         let _this = this
 3         if (tag === ‘sTime‘) {
 4           let s = _this.timeToNum(_this.source_obj.startDate)
 5           let e = _this.timeToNum(value)
 6           if (e > s) {
 7             _this.e_startDate = value
 8             console.log(_this.e_startDate, _this.e_endDate)
 9           }
10         } else {
11           let e = _this.timeToNum(_this.source_obj.endDate)
12           let s = _this.timeToNum(value)
13           if (e > s) {
14             _this.s_endDate = value
15           }
16         }
17       },

时间对比

      timeToNum (time) {
        let str = ‘‘
        str = time.replace(/-/g, ‘‘)
        let num = parseInt(str)
        return num
      },

 

思路大概就是这样啦,总体代码自己写吧
