It seems to be very popular recently. I wrote a js function to implement it.

<!

The C # background implementation method is useful on the Internet. For ease of viewing, paste it below :)

The Code is as follows:


Public string DateStringFromNow (DateTime dt)
{
TimeSpan span = DateTime. Now-dt;
If (span. TotalDays> 60)
{
Return dt. tow.datestring ();
}
Else
If (span. TotalDays> 30)
{
Return
"1 month ago ";
}
Else
If (span. TotalDays> 14)
{
Return
"2 weeks ago ";
}
Else
If (span. TotalDays> 7)
{
Return
"1 week ago ";
}
Else
If (span. TotalDays> 1)
{
Return
String. Format ("{0} Days Ago", (int) Math. Floor (span. TotalDays ));
}
Else
If (span. TotalHours> 1)
{
Return
String. Format ("{0} Hours Ago", (int) Math. Floor (span. TotalHours ));
}
Else
If (span. TotalMinutes> 1)
{
Return
String. Format ("{0} Minutes Ago", (int) Math. Floor (span. TotalMinutes ));
}
Else
If (span. TotalSeconds> = 1)
{
Return
String. Format ("{0} seconds ago", (int) Math. Floor (span. TotalSeconds ));
}
Else
{
Return
"1 second ago ";
}
}
