| /** |
| * The DateLocale class is a container and base class for all |
| * localised date strings used by YAHOO.util.Date. It is used |
| * internally, but may be extended to provide new date localisations. |
| * |
| * To create your own DateLocale, follow these steps: |
| * <ol> |
| * <li>Find an existing locale that matches closely with your needs</li> |
| * <li>Use this as your base class. Use YAHOO.util.DateLocale if nothing |
| * matches.</li> |
| * <li>Create your own class as an extension of the base class using |
| * YAHOO.lang.merge, and add your own localisations where needed.</li> |
| * </ol> |
| * See the YAHOO.util.DateLocale['en-US'] and YAHOO.util.DateLocale['en-GB'] |
| * classes which extend YAHOO.util.DateLocale['en']. |
| * |
| * For example, to implement locales for French french and Canadian french, |
| * we would do the following: |
| * <ol> |
| * <li>For French french, we have no existing similar locale, so use |
| * YAHOO.util.DateLocale as the base, and extend it: |
| * <pre> |
| * YAHOO.util.DateLocale['fr'] = YAHOO.lang.merge(YAHOO.util.DateLocale, { |
| * a: ['dim', 'lun', 'mar', 'mer', 'jeu', 'ven', 'sam'], |
| * A: ['dimanche', 'lundi', 'mardi', 'mercredi', 'jeudi', 'vendredi', 'samedi'], |
| * b: ['jan', 'fév', 'mar', 'avr', 'mai', 'jun', 'jui', 'aoû', 'sep', 'oct', 'nov', 'déc'], |
| * B: ['janvier', 'février', 'mars', 'avril', 'mai', 'juin', 'juillet', 'août', 'septembre', 'octobre', 'novembre', 'décembre'], |
| * c: '%a %d %b %Y %T %Z', |
| * p: ['', ''], |
| * P: ['', ''], |
| * x: '%d.%m.%Y', |
| * X: '%T' |
| * }); |
| * </pre> |
| * </li> |
| * <li>For Canadian french, we start with French french and change the meaning of \%x: |
| * <pre> |
| * YAHOO.util.DateLocale['fr-CA'] = YAHOO.lang.merge(YAHOO.util.DateLocale['fr'], { |
| * x: '%Y-%m-%d' |
| * }); |
| * </pre> |
| * </li> |
| * </ol> |
| * |
| * With that, you can use your new locales: |
| * <pre> |
| * var d = new Date("2008/04/22"); |
| * YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr"); |
| * </pre> |
| * will return: |
| * <pre> |
