微信小程序 时间戳距当前时间的长度

注意：传入的dateTimeStamp时间戳以秒计时。如你想传以毫秒计时的值时先除1000

getDateDiff:function (dateTimeStamp) {

  var minute =  60;

  var hour = minute * 60;

  var day = hour * 24;

  var halfamonth = day * 15;

  var month = day * 30;

  var now = Date.parse(new Date())/1000   //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;

  var result = ''

  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
