From be5ada56ccd21397c9fac9dfcb5ced576e770552 Mon Sep 17 00:00:00 2001 From: Owen Leonard Date: Fri, 1 Jun 2012 10:09:30 -0400 Subject: [PATCH] Bug 7747 [FOLLOW-UP] Replace YUI autocomplete with jQueryUI This patch removes the template calls to the now-obsolete YUI JS dependencies and removes the relevant YUI files themselves. First two work perfectly, circulation search header and overdues patron authorized value. Authorities search does not seem to work, old yui file are still referenced in auth_finder.tt. The jquery works, but data set is not found, or I messed up my authority record.

It is used - * internally, but may be extended to provide new date localisations. - * - * To create your own DateLocale, follow these steps: - *
      - *
    1. Find an existing locale that matches closely with your needs
      2. - *
    2. Use this as your base class. Use YAHOO.util.DateLocale if nothing - * matches.
      3. - *
    3. Create your own class as an extension of the base class using - * YAHOO.lang.merge, and add your own localisations where needed.
      4. - *
    - * 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: - *
      - *
    1. For French french, we have no existing similar locale, so use - * YAHOO.util.DateLocale as the base, and extend it: - * 
      - *      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'
- *      });
- *
      - *
      2. - *
    2. For Canadian french, we start with French french and change the meaning of \%x: - * 
      - *      YAHOO.util.DateLocale['fr-CA'] = YAHOO.lang.merge(YAHOO.util.DateLocale['fr'], {
- *          x: '%Y-%m-%d'
- *      });
- *
      - *
      3. - *
    - * - * With that, you can use your new locales: - * 
    - *    var d = new Date("2008/04/22");
- *    YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr");
- *
    - * will return: - * 
    - *    mardi, 22 avril == 22.04.2008
- *
    - * And - * 
    - *    YAHOO.util.Date.format(d, {format: "%A, %d %B == %x"}, "fr-CA");
- *
    - * Will return: - *
