js实现回看近七天日期

function strFormat(str) {
    return str < 10 ? `0${str}` : str
}
//时间戳转日期
export function timeStamp(time) {
    const dates = new Date(time)
    const year = dates.getFullYear()
    const month = dates.getMonth() + 1
    const date = dates.getDate()
    const day = dates.getDay()
    const hour = dates.getHours()
    const min = dates.getMinutes()
    const days = ['日', '一', '二', '三', '四', '五', '六']
    return {
        allDate: `${year}/${strFormat(month)}/${strFormat(date)}`,
        date: `${strFormat(month)}-${strFormat(date)}`, //返回的日期 07-01
        day: `星期${days[day]}`, //返回的礼拜天数  星期一
        hour: strFormat(hour) + ':' + strFormat(min) //返回的时钟 08:00
    }
}
//获取最近7天的日期和礼拜天数
export function dateData() {
    const time = []
    const date = new Date()
    const now = date.getTime() //获取当前日期的时间戳
    let timeStr = 3600 * 24 * 1000 //一天的时间戳
    for (let i = 0; i < 7; i++) {
        const timeObj = {}
        timeObj.date = timeStamp(now + timeStr * -i).date //保存日期
        timeObj.timeStamp = now + timeStr * -i //保存时间戳
        console.log(timeObj.timeStamp)
        if (i == 0) {
            timeObj.week = '今天'
        } else if (i == 1) {
            timeObj.week = '昨天'
        }else {
            timeObj.week = timeStamp(now + timeStr * i).day
        }
        time.push(timeObj)
    }
    return time
}
//时间数组
export function timeData(startTime = '08:00', endTime = '18:30', timeInterval = 0.5) {
    const time = []
    const date = timeStamp(Date.now()).allDate
    const startDate = `${date} ${startTime}`
    const endDate = `${date} ${endTime}`
    const startTimeStamp = new Date(startDate).getTime()
    const endTimeStamp = new Date(endDate).getTime()
    const timeStr = 3600 * 1000 * timeInterval
    for (let i = startTimeStamp; i <= endTimeStamp; i = i + timeStr) {
        const timeObj = {}
        timeObj.time = timeStamp(i).hour
        timeObj.disable = 1
        time.push(timeObj)
    }
    return time
}

• 然后在需要的页面直接引入这个方法即可dateData
