Js程式碼如下：

function getDateDiff(dateTimeStamp){
  var result;
    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){
    if(monthC<=12)
          result="" + parseInt(monthC) + "月前";
    else{
      result="" + parseInt(monthC/12) + "年前";
    }
    }
    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) +"小時前";
    }
    else if(minC>=1){
        result=""+ parseInt(minC) +"分鐘前";
    }else{
    result="剛剛";
  }
    return result;
};
