Do you have a pretty date?

29 janvier 2008

John Resig has created a little script to give you pretty dates that Web 2.0 know and love :

Plain text Javascript :

prettyDate("2008-01-28T20:24:17Z") // => "2 hours ago"

prettyDate("2008-01-27T22:24:17Z") // => "Yesterday"

prettyDate("2008-01-26T22:24:17Z") // => "2 days ago"

prettyDate("2008-01-14T22:24:17Z") // => "2 weeks ago"

the library is short and sweet:

Plain text Javascript :

/*

* JavaScript Pretty Date

* Copyright (c) 2008 John Resig (jquery.com)

* Licensed under the MIT license.

*/

// Takes an ISO time and returns a string representing how

// long ago the date represents.

function prettyDate(time){

var date = new Date((time || "").replace(/-/g,"/").replace(/[TZ]/g," ")),

diff = (((new Date()).getTime() - date.getTime()) / 1000),

day_diff = Math.floor(diff / 86400);

if ( isNaN(day_diff) || day_diff <0 || day_diff>= 31 )

return;

return day_diff == 0 && (

diff <60 && "just now" ||

diff <120 && "1 minute ago" ||

diff <3600 && Math.floor( diff / 60 ) + " minutes ago" ||

diff <7200 && "1 hour ago" ||

diff <86400 && Math.floor( diff / 3600 ) + " hours ago") ||

day_diff == 1 && "Yesterday" ||

day_diff <7 && day_diff + " days ago" ||

day_diff <31 && Math.ceil( day_diff / 7 ) + " weeks ago";

}
