【微信小程序】时间戳转换

本章主要讲时间戳转换成时间，Y/M/D h:m:s（年月日时分秒）

将js代码放到utils文件的utils.js中

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 formatTimeTwo(number, format) {
  var formateArr = ['Y', 'M', 'D', 'h', 'm', 's'];
  var returnArr = [];
  // var date = new Date(number * 1000);//时间戳为10位
  var date = new Date(number );//时间戳为13位
  returnArr.push(date.getFullYear());
  returnArr.push(formatNumber(date.getMonth() + 1));
  returnArr.push(formatNumber(date.getDate()));

  returnArr.push(formatNumber(date.getHours()));
  returnArr.push(formatNumber(date.getMinutes()));
  returnArr.push(formatNumber(date.getSeconds()));

  for (var i in returnArr) {
    format = format.replace(formateArr[i], returnArr[i]);
  }
  return format;
}
module.exports = {
  formatTime: formatTime,
  formatTimeTwo: formatTimeTwo
}

在需要需要进行时间戳转换页面的js文件中引用utils.js

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

console.log(time.formatTimeTwo(需转换的字段名, 'Y/M/D h:m:s'));
console.log(time.formatTimeTwo(字段名, 'Y/M/D'));
console.log(time.formatTimeTwo(字段名, 'h:m'));
