|
|
|
3043 |
* The DateLocale class is a container and base class for all
|
|
|
3044 |
* localised date strings used by YAHOO.util.Date. It is used
|
|
|
3045 |
* internally, but may be extended to provide new date localisations.
|
|
|
3046 |
*
|
|
|
3047 |
* To create your own DateLocale, follow these steps:
|
|
|
3048 |
* <ol>
|
|
|
3049 |
* <li>Find an existing locale that matches closely with your needs</li>
|
|
|
3050 |
* <li>Use this as your base class. Use YAHOO.util.DateLocale if nothing
|
|
|
3051 |
* matches.</li>
|
|
|
3052 |
* <li>Create your own class as an extension of the base class using
|
|
|
3053 |
* YAHOO.lang.merge, and add your own localisations where needed.</li>
|
|
|
3054 |
* </ol>
|
|
|
3055 |
* See the YAHOO.util.DateLocale['en-US'] and YAHOO.util.DateLocale['en-GB']
|
|
|
3056 |
* classes which extend YAHOO.util.DateLocale['en'].
|
|
|
3057 |
*
|
|
|
3058 |
* For example, to implement locales for French french and Canadian french,
|
|
|
3059 |
* we would do the following:
|
|
|
3060 |
* <ol>
|
|
|
3061 |
* <li>For French french, we have no existing similar locale, so use
|
|
|
3062 |
* YAHOO.util.DateLocale as the base, and extend it:
|
|
|
3063 |
* <pre>
|
|

3064 |
* YAHOO.util.DateLocale['fr'] = YAHOO.lang.merge(YAHOO.util.DateLocale, {

3075 |
* </pre>
|
|
|
3076 |
* </li>
|
|
|
3077 |

3078 |
