jQuery Datepicker localization

Question

I need a french calendar and I can\'t understand the problem. I guess I\'m not using the regional options like it should be. But...

Here is my code :

You must extend the regional options like this (code split on multiple lines for readability):

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

The order of parameters is important because of the way jQuery.extend works. Two incorrect examples:

/*
 * 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"]);

PS: you also need to load the jQuery UI i18n files:
