以下是具体的月星期

function formatDate(date) {
            const mistiming = Math.round((Date.now() - new Date(date).getTime()) / 1000)
            const tags = ['年', '个月', '星期', '天', '小时', '分钟', '秒']
            const times = [31536000, 2592000, 604800, 86400, 3600, 60, 1]
            for (let i = 0; i < times.length; i++) {
                const inm = Math.floor(mistiming / times[i])
                if (tags[i] === '天') {
                    switch (inm) {
                        case 0:
                            return '今天'
                            break
                        case 1:
                            return '昨天'
                            break
                        case 2:
                            return '前天'
                            break
                        default:

                            break;
                    }
                }
                if (inm !== 0) {

除今年日期之前的都添加年

function timestampToTime(timestamp) {
                let date =new Date(timestamp),//时间戳为10位需*1000，时间戳为13位的话不需乘1000
                    Y = date.getFullYear(),
                    M = (date.getMonth() +1 <10 ?'0' + (date.getMonth() +1) : date.getMonth() +1),
                    D = date.getDate(),
                    h = date.getHours() +':',
                    m = date.getMinutes() +':',
                    s = date.getSeconds(),
                    newY=new Date().getFullYear();  //2021
                    // console.log(newY>=Y)
                    // console.log(newY,'今年时间======')  //2020
                    // console.log(Y,'去年时间======')  //2020
                    if(newY===Y){  //
                        return M +'-'+D; //时分秒可以根据自己的需求加上
                    }else{
                        return Y +'-'+M +'-'+D;
                    }

                }
