小程序调模块化调用

util.js

const formatTime = date => {
  const year = date.getFullYear()
  const month = date.getMonth() + 1
  const day = date.getDate()
  const hour = date.getHours()
  const minute = date.getMinutes()
  const second = date.getSeconds()

  return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}

const formatNumber = n => {
  n = n.toString()
  return n[1] ? n : '0' + n
}

module.exports = {
  formatTime: formatTime
}

//logs.js

const util = require('../../utils/util.js')

Page({
  data: {
    logs: []
  },
  onLoad: function () {
    this.setData({
      logs: (wx.getStorageSync('logs') || []).map(log => {
        return util.formatTime(new Date(log))
      })
    })
  }
})
