I know yesterday post supposed to be the last 'till the the end of the month but I could not resits. Dustin Diaz twitted anyone trying to parse our wonky rails dates in JS. do this: var date = Date.parse(str.replace(/( \+)/, ' UTC$1')); seems to fix it. Again, I could not resist to create a toUTCString based function to create JSON strings and to parse them back. This is the result and apparently is both the fastest implementation I know and cross browser (Chrome, Firefox, Inernet Explorer, Safari). This is a quick post so if you find some problem please let me know, thanks. (function(){ // WebReflection Fast Date.prototype.toJSON and Date.fromJSON Suggestion var rd = /^.{5}(\d{1,2}).(.{3}).(.{4}).(.{2}).(.{2}).(.{2}).+$/, rs = /^(.{4}).(.{2}).(.{2}).(.{2}).(.{2}).(.{2}).+$/, d = new Date, f = /(GMT|UTC)$/.exec(d.toUTCString())[1], // cheers gazheyes m = {}, i = 0, s = "" ; d.setUTCDate(1); while(i < 12){ d.setUTCMonth(i)...

During last evenings I have updated a little bit my vice-versa project . Since vice-versa aim is to bring in every browser what is possible to implement and, in most of the cases, already defined as standard (from W3 or MSDN when it is worthy) I decided to get rid of the Ariel Flesler fast trim proposal to introduce my lightweight full specs String.prototype.trim, trimLeft, and trimRight. For full specs I mean that vice-versa String.prototype.trim replace exactly same characters replaced by native Firefox 3.5 implementation, rather than only characters which code is less than 33 as is for Ariel proposal. The good part of vice-versa ( to be honest I cannot find bad parts so far ;) ) is that every single file is stand-alone, so if you do not like benefits the entire " lib " could bring, you can always adopt only one of its files, for example the String one, the Array one, or the last full specs ECMAScript 5 Date constructor , compatible with ISO strings, new Date("2009-0...

One most than welcome new entry of ECMAScript 5 is the Date.prototype.toISOString function and ability for Date constructor to accept an ISO String and to generate a Date instance. This feature will make JSON Date instances import/export extremely fast and simple, but why should we wait ES5 release when we can have both features now? Full Specs ISO 8601 Parser Plus Unobtrusive toISOString Method We all do not like that much to extend native JavaScript constructors, so here I am with a proposal that will not touch the Date prototype: if(!Date.ISO)(function(){"use strict"; /** ES5 ISO Date Parser Plus toISOString Method * @author Andrea Giammarchi * @blog WebReflection * @version 2009-07-04T11:36:25.123Z * @compatibility Chrome, Firefox, IE 5+, Opera, Safari, WebKit, Others */ function ISO(s){ var m = /^(\d{4})(-(\d{2})(-(\d{2})(T(\d{2}):(\d{2})(:(\d{2})(\.(\d+))?)?(Z|((\+|-)(\d{2}):(\d{2}))))?)?)?$/.exec(s); if(m === null) thr...
