js格式化时间：几月/周/小时/分钟前，nodejs调用

创建工具/模块

timeutil.js

exports.getDateDiff = function (stringTime){
        stringTime = stringTime.substring(0, 19);
        var dateTimeStamp = Date.parse(new Date(stringTime));
        var minute = 1000 * 60;
        var hour = minute * 60;
        var day = hour * 24;
        var halfamonth = day * 15;
        var month = day * 30;
        var now = new Date().getTime();
        var diffValue = now - dateTimeStamp;
        if(diffValue < 0){return;}
        var monthC =diffValue/month;
        var weekC =diffValue/(7*day);
        var dayC =diffValue/day;
        var hourC =diffValue/hour;
        var minC =diffValue/minute;
        if(monthC>=1){
                result="" + parseInt(monthC) + "月前";
        }
        else if(weekC>=1){
                result="" + parseInt(weekC) + "周前";
        }
        else if(dayC>=1){
                result=""+ parseInt(dayC) +"天前";
        }
        else if(hourC>=1){
                result=""+ parseInt(hourC) +"小时前";
        }
        else if(minC>=1){
                result=""+ parseInt(minC) +"分钟前";
        }else
        result="刚刚";
        return result;
}

nodejs调用:

timeFormat.js

var timeutil = require('./timeutil')
var time = "2017-09-08T02:47:22.236Z";
console.log(timeutil.getDateDiff(time));

执行结果：

➜ node timeformat.js
