微信小程序封装时间组件

先写一个时间函数

//在utils
function formatTime(date) {
  var year = date.getFullYear()
  var month = date.getMonth() + 1
  var day = date.getDate()
  var hour = date.getHours()
  var minute = date.getMinutes()
  var second = date.getSeconds()
  return [year, month, day].map(formatNumber).join('/') + ' ' + [hour, minute, second].map(formatNumber).join(':')
}

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

module.exports = {
  formatTime: formatTime,
}

在使用页面引入使用

let util = require('../../../../utils/Byron/index')
let time = util.formatTime2(new Date())

如果想要获取年月日的格式

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