小程序时间格式大全

下面文章方面比较全面，可以看看：
JavaScript Date（日期）对象

这个是创建项目的时候，官方提供的 utils/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
}

是带有具体时间的，我们可以根据它的代码，自定义时间格式。

const formatTime = date => {
  const year = date.getFullYear()
  const month = date.getMonth() + 1
  const day = date.getDate()

  // return `${[year, month, day].map(formatNumber).join('-')}`
  return year + "年" + month + "月" + day + "日"
}

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

module.exports = {
  formatTime
}

引入js文件
在需要用到这个utils的页面的js文件顶部添加以下代码。注意自己更改文件路径。

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

用的时候，直接🤗

util.formatTime(new Date());

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(':')
}

// 获取当前日期，以“/”连接
const formatDate = date => {
    const year = date.getFullYear()
    const month = date.getMonth() + 1
    const day = date.getDate()

    return [year, month, day].map(formatNumber).join('/')
}

// 获取当前日期，以“年月日”连接
const formatDateCH = date => {
  const year = date.getFullYear()
  const month = date.getMonth() + 1
  const day = date.getDate()

  return year + "年" + month + "月" + day + "日"
}

// 获取当前日期，以“-”连接
const formatDateByH = date => {
    const year = date.getFullYear()
    const month = date.getMonth() + 1
    const day = date.getDate()

    return [year, month, day].map(formatNumber).join('-')
}

// 将string格式日期转换为“/”连接只包含月日的日期
const formatDateToSimple = data => {
    var date = new Date(Date.parse(data));
    const month = date.getMonth() + 1
    const day = date.getDate()

    return [month, day].join('/')
}

// 获取string格式日期的星期
const formatDateToWeek = data => {
    var date = new Date(Date.parse(data));
    const month = date.getDay();
    var weekDay ;
    switch (month){
