貌似最近很流行這個，就寫了個js函數(shù)實(shí)現(xiàn)之

網(wǎng)上有用C#后臺實(shí)現(xiàn)的方法，為方便查看就轉(zhuǎn)貼到下面吧：）

復(fù)制代碼代碼如下:

public string DateStringFromNow(DateTime dt) 
{ 
TimeSpan span = DateTime.Now - dt; 
if (span.TotalDays >60) 
{ 
return dt.ToShortDateString(); 
} 
else 
if ( span.TotalDays >30 ) 
{ 
return 
"1個月前"; 
} 
else 
if (span.TotalDays >14) 
{ 
return 
"2周前"; 
} 
else 
if (span.TotalDays >7) 
{ 
return 
"1周前"; 
} 
else 
if (span.TotalDays >1) 
{ 
return 
string.Format("{0}天前", (int)Math.Floor(span.TotalDays)); 
} 
else 
if (span.TotalHours >1) 
{ 
return 
string.Format("{0}小時前", (int)Math.Floor(span.TotalHours)); 
} 
else 
if (span.TotalMinutes >1) 
{ 
return 
string.Format("{0}分鐘前", (int)Math.Floor(span.TotalMinutes)); 
} 
else 
if (span.TotalSeconds >=1) 
{ 
return 
string.Format("{0}秒前", (int)Math.Floor(span.TotalSeconds)); 
} 
else 
{ 
return 
"1秒前"; 
} 
}
