微信公众号 - js传入时间戳换算（以前几天、几小时...）

 // 获取当前时间戳
 function timestamps() {
   return Math.round(new Date().getTime() / 1000).toString()
 }

 // 距离时间... 传时间戳
 function timeFormat(timestamps) {
   timestamps = timestamps * 1000
   let daySec, dayMin, dayHour, dayS
   let timeNow = new Date().getTime()
   let ts = (timeNow - timestamps) / 1000
   dayS = Math.round(ts / (24 * 60 * 60))
   dayHour = Math.round(ts / (60 * 60))
   dayMin = Math.round(ts / 60)
   daySec = Math.round(ts)
   if (dayS > 0 && dayS < 2) {
     return `${dayS} 天以前`
   } else if (dayS <= 0 && dayHour > 0) {
     return `${dayHour} 小时以前`
   } else if (dayHour <= 0 && dayMin > 0) {
     return `${dayMin} 分钟以前`
   } else if (dayMin <= 0 && daySec >= 0) {
     return '现在'
   } else {
     let timestamp = new Date()
     timestamp.setTime(timestamps)
     return [timestamp.getFullYear(), timestamp.getMonth() + 1, timestamp.getDate()].map(this.formatNumber).join('/') + ' ' + [timestamp.getHours(), timestamp.getMinutes()].map(this.formatNumber).join(':')
   }
 }

 function formatNumber(n) {
   n = n.toString()
   return n[1] ? n : `0${n}`
 }

 console.log(timestamps(), timeFormat(1534494126));
