¿Cómo puedo localizar el selector de fechas de jQuery UI?

Realmente necesito un calendario desplegable localizado. Un calendario en inglés no comunica exactamente la excelencia en un sitio web noruego ;-)

He experimentado con jQuery DatePicker , su sitio web dice que se puede localizar, sin embargo, eso no parece funcionar.

Estoy usando ASPNET.MVC y realmente quiero ceñirme a una biblioteca de JavaScript. En este caso jQuery.

El calendario del kit de herramientas ajax sería aceptable, si solo mostrara nombres noruegos.

Actualización: ¡Impresionante! Veo que me faltan los archivos de idioma, un detalle no tan pequeño :-)

Para aquellos que aún tienen problemas, debe descargar el archivo de idioma que desee desde aquí:

https://github.com/jquery/jquery-ui/tree/master/ui/i18n

y luego inclúyalo en su página como esta, por ejemplo (idioma italiano):

<script type="text/javascript" src="/scripts/jquery.ui.datepicker-it.js"></script>

luego usa el código de zilverdistel : D

Descubrí la demostración y la implementé de la siguiente manera:

$.datepicker.setDefaults(
  $.extend(
    {'dateFormat':'dd-mm-yy'},
    $.datepicker.regional['nl']
  )
);

También necesitaba establecer el formato predeterminado para la fecha ...

La cadena $.datepicker.regional['it']no traduce todas las palabras.

Para traducir el selector de fechas debe especificar algunas variables:

$.datepicker.regional['it'] = {
    closeText: 'Chiudi', // set a close button text
    currentText: 'Oggi', // set today text
    monthNames: ['Gennaio','Febbraio','Marzo','Aprile','Maggio','Giugno',   'Luglio','Agosto','Settembre','Ottobre','Novembre','Dicembre'], // set month names
    monthNamesShort: ['Gen','Feb','Mar','Apr','Mag','Giu','Lug','Ago','Set','Ott','Nov','Dic'], // set short month names
    dayNames: ['Domenica','Luned&#236','Marted&#236','Mercoled&#236','Gioved&#236','Venerd&#236','Sabato'], // set days names
    dayNamesShort: ['Dom','Lun','Mar','Mer','Gio','Ven','Sab'], // set short day names
    dayNamesMin: ['Do','Lu','Ma','Me','Gio','Ve','Sa'], // set more short days names
    dateFormat: 'dd/mm/yy' // set format date
};

$.datepicker.setDefaults($.datepicker.regional['it']);

$(".datepicker").datepicker();

En este caso, su selector de fechas está traducido correctamente.

  $.datepicker.setDefaults({
    closeText: "关闭",
    prevText: "<上月",
    nextText: "下月>",
    currentText: "今天",
    monthNames: [ "一月","二月","三月","四月","五月","六月",
    "七月","八月","九月","十月","十一月","十二月" ],
    monthNamesShort: [ "一月","二月","三月","四月","五月","六月",
    "七月","八月","九月","十月","十一月","十二月" ],
    dayNames: [ "星期日","星期一","星期二","星期三","星期四","星期五","星期六" ],
    dayNamesShort: [ "周日","周一","周二","周三","周四","周五","周六" ],
    dayNamesMin: [ "日","一","二","三","四","五","六" ],
    weekHeader: "周",
    dateFormat: "yy-mm-dd",
    firstDay: 1,
    isRTL: false,
    showMonthAfterYear: true,
    yearSuffix: "年"
  });

el código i18n se puede copiar de https://github.com/jquery/jquery-ui/tree/master/ui/i18n

1. Necesita cargar los archivos jQuery UI i18n:

<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/i18n/jquery-ui-i18n.min.js">
</script>

2. Utilice la $.datepicker.setDefaultsfunción para establecer valores predeterminados para TODOS los selectores de fechas.

3. En caso de que desee anular la (s) configuración (es) antes de configurar los valores predeterminados, puede usar esto:

var options = $.extend(
    {},                                  // empty object
    $.datepicker.regional["fr"],         // fr regional
    { dateFormat: "d MM, y" /*, ... */ } // your custom options
);
$.datepicker.setDefaults(options);

El orden de los parámetros es importante debido a la forma en que jQuery.extendfunciona. Dos ejemplos incorrectos:

/*
 * This overwrites the global variable itself instead of creating a
 * customized copy of french regional settings
 */
$.extend($.datepicker.regional["fr"], { dateFormat: "d MM, y"});

/*
 * The desired dateFormat is overwritten by french regional 
 * settings' date format
 */
$.extend({ dateFormat: "d MM, y"}, $.datepicker.regional["fr"]);

A continuación, se muestra un ejemplo de cómo puede realizar la localización sin una biblioteca adicional.

jQuery(function($) {
  $('input.datetimepicker').datepicker({
    duration: '',
    changeMonth: false,
    changeYear: false,
    yearRange: '2010:2020',
    showTime: false,
    time24h: true
  });

  $.datepicker.regional['cs'] = {
    closeText: 'Zavřít',
    prevText: '<Dříve',
    nextText: 'Později>',
    currentText: 'Nyní',
    monthNames: ['leden', 'únor', 'březen', 'duben', 'květen', 'červen', 'červenec', 'srpen',
      'září', 'říjen', 'listopad', 'prosinec'
    ],
    monthNamesShort: ['led', 'úno', 'bře', 'dub', 'kvě', 'čer', 'čvc', 'srp', 'zář', 'říj', 'lis', 'pro'],
    dayNames: ['neděle', 'pondělí', 'úterý', 'středa', 'čtvrtek', 'pátek', 'sobota'],
    dayNamesShort: ['ne', 'po', 'út', 'st', 'čt', 'pá', 'so'],
    dayNamesMin: ['ne', 'po', 'út', 'st', 'čt', 'pá', 'so'],
    weekHeader: 'Týd',
    dateFormat: 'dd/mm/yy',
    firstDay: 1,
    isRTL: false,
    showMonthAfterYear: false,
    yearSuffix: ''
  };

  $.datepicker.setDefaults($.datepicker.regional['cs']);
});

Si usa el selector de fechas y moment.js de jQuery UI en el mismo proyecto, debe aprovechar los datos de la configuración regional de moment.js:

// Finnish. you need to include separate locale file for each locale: https://github.com/moment/moment/tree/develop/locale
moment.locale('fi'); 

// fetch locale data internal structure, so we can shove it inside jQuery UI
var momentLocaleData = moment.localeData(); 

$.datepicker.regional['user'] = {
    monthNames: momentLocaleData._months,
    monthNamesShort: momentLocaleData._monthsShort,
    dayNames: momentLocaleData._weekdays,
    dayNamesShort: momentLocaleData._weekdaysMin,
    dayNamesMin: momentLocaleData._weekdaysMin,
    firstDay: momentLocaleData._week.dow,
    dateFormat: 'yy-mm-dd' // "2016-11-22". date formatting tokens are not easily interchangeable between momentjs and jQuery UI (https://github.com/moment/moment/issues/890)
};

$.datepicker.setDefaults($.datepicker.regional['user']);

en caso de que alguien TODAVÍA esté atascado en esto, a pesar de las otras respuestas, lo resolví con:

$.datepicker.setDefaults($.datepicker.regional['en-GB']);

tenga en cuenta los 'GB' adicionales. Después de eso funcionó bien.

Esta solución puede ayudar.

$(document).ready(function () {
  var userLang = navigator.language || navigator.userLanguage;

  var options = $.extend({},
    $.datepicker.regional["ja"], {
      dateFormat: "yy/mm/dd",
      changeMonth: true,
      changeYear: true,
      highlightWeek: true
    }
  );

  $("#japaneseCalendar").datepicker(options);
});

Lo resolví agregando la propiedad data-date-language="it":

  $('#TxtDaDataDoc_Val').datepicker();
});
