微信小程序使用wxs将时间戳转化为几天前

需求描述: 文件创建时间与当前时间小于24小时,显示小时数,大于24小时,显示天数,时间戳转化为几天前，几小时前，几分钟前

代码演示wxs

var getDateDiff = function (dateTimeStamp) {
    var minute = 1000 * 60;
    var hour = minute * 60;
    var day = hour * 24;
    var halfamonth = day * 15;
    var month = day * 30;
    var now = getDate();//有些特殊 不能使用 new Date()
    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;
};//时间戳转化为几天前，几小时前，几分钟前
