就近值 reduce用法时间戳与时间点对比循环查找

后台接口返回的13为时间戳
需要与数据data的time做对比，查找出最近的值
data的数据结构如下：
在这里插入图片描述
将：改为空格，变成数字之间的对比

//查找最近的时间getNearestTime(timestamp, data) {let date = new Date(timestamp)let h = date.getHours()let m = (date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes())let hm = parseInt(h + '' + m)let nearestTime = ''let distance = 1000000for (let i in data) {let time = parseInt(data[i].time.replace(':', ''))let dis = Math.abs(hm - time)if (dis < distance) {distance = disnearestTime = data[i].time}}return nearestTime},let nearestWakeupTimeStart = this.getNearestTime(wakeupTimeStart, this.heartListData)

infos(timestamp, data){let date = new Date(timestamp)let h = date.getHours() < 10 ? '0' + date.getHours() : date.getHours()let m = date.getMinutes() < 10 ? '0' + date.getMinutes() : date.getMinutes()let targetDate = h + '' + mvar closestDate = data.reduce((prev, curr) => {var prevDiff = Math.abs(targetDate - prev.time.replace(':', ''));var currDiff = Math.abs(targetDate - curr.time.replace(':', ''));return currDiff < prevDiff ? curr : prev;});return closestDate.time},let nearestWakeupTimeStarts =  this.infos(wakeupTimeStart, this.heartListData)
