貌似最近很流行这个，就写了个js函数实现之

最近研究android，用java写的实现方法

public static String getTimeDiff(Date date) {Calendar cal = Calendar.getInstance();long diff = 0;Date dnow = cal.getTime();String str = "";diff = dnow.getTime() - date.getTime();if  (diff > 2592000000L) {//30 * 24 * 60 * 60 * 1000=2592000000 毫秒str="1个月前";} else if  (diff > 1814400000) {//21 * 24 * 60 * 60 * 1000=1814400000 毫秒str="3周前";} else if  (diff > 1209600000) {//14 * 24 * 60 * 60 * 1000=1209600000 毫秒str="2周前";} else if  (diff > 604800000) {//7 * 24 * 60 * 60 * 1000=604800000 毫秒str="1周前";} else if (diff > 86400000) {//24 * 60 * 60 * 1000=86400000 毫秒//System.out.println("X天前");str=(int)Math.floor(diff/86400000f) + "天前";} else if (diff > 18000000 ) {//5 * 60 * 60 * 1000=18000000 毫秒//System.out.println("X小时前");str=(int)Math.floor(diff/18000000f) + "小时前";} else if (diff > 60000) {//1 * 60 * 1000=60000 毫秒//System.out.println("X分钟前");str=(int)Math.floor(diff/60000) +"分钟前";}else{str=(int)Math.floor(diff/1000) +"秒前";}return str;}

网上有用C#后台实现的方法，为方便查看就转贴到下面吧：）

public string DateStringFromNow(DateTime dt)    {    TimeSpan span = DateTime.Now - dt;    if (span.TotalDays >60)    {    return dt.ToShortDateString();    }    elseif ( span.TotalDays >30 )    {    return"1个月前";    }    elseif (span.TotalDays >14)    {    return"2周前";    }    elseif (span.TotalDays >7)    {    return"1周前";    }    elseif (span.TotalDays >1)    {    returnstring.Format("{0}天前", (int)Math.Floor(span.TotalDays));    }    elseif (span.TotalHours >1)    {    returnstring.Format("{0}小时前", (int)Math.Floor(span.TotalHours));    }    elseif (span.TotalMinutes >1)    {    returnstring.Format("{0}分钟前", (int)Math.Floor(span.TotalMinutes));    }    elseif (span.TotalSeconds >=1)    {    returnstring.Format("{0}秒前", (int)Math.Floor(span.TotalSeconds));    }    else {    return"1秒前";    }    }
