微信小程序，时间戳和日期格式互相转化

module.exports = {
    formatTime: formatTime,  // 日期转时间戳
    formatTimeTwo: formatTimeTwo  // 时间戳转日期

}

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
}

/** 
 * 时间戳转化为年 月 日 时 分 秒 
 * number: 传入时间戳 
 * format：返回格式，支持自定义，但参数必须与formateArr里保持一致 
*/
function formatTimeTwo(number, format) {

    var formateArr = ['Y', 'M', 'D', 'h', 'm', 's'];
    var returnArr = [];

    var date = new Date(number * 1000);
    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  
}

var time = require('../../utils/util.js');

 var sjc = 1488481383;
    console.log(time.formatTime(sjc,'Y/M/D h:m:s'));
    console.log(time.formatTime(sjc, 'h:m'));



得到的效果如下：
