1.新建立js檔案如圖

2.寫入相關方法並經行測試

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}`
}

function test(params) {
  console.log(123);
}


module.exports = {
  formatTime,
  test
}

3.測試繼承

const util = require('../../utils/util');
Page({

  /**
   * 頁面的初始資料
   */
  data: {
    wx_login_title:'微信一鍵登陸',
    phone_title:'手機號碼登陸'
  },

  
 
/**
   * 生命週期函式--監聽頁面載入
   */
  onLoad: function (options) {
    util.test();
  },
  wx_login_botton: function(e){
    const url = '/pages/index/index';
    getApp().authgetuserinfo(url);//微信登陸後
  },
  phone_login_botton: function(e){
    console.log(this.data.phone_title);
    wx.navigateTo({
      url: '/pages/login/phone/phone_login?id=1'
    })
  }
})
