jQuery DatePicker显示中文（本地化）

jquery-datepicker内置了对本地化的支持，在i18n/目录下放置了各种语言的本地化配置。在使用时引入对应的文件即可。

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

查看datepicker-zh-CN.js的源码配置如下：

/* Chinese initialisation for the jQuery UI date picker plugin. */
/* Written by Cloudream (cloudream@gmail.com). */
( function( factory ) {
    if ( typeof define === "function" && define.amd ) {

        // AMD. Register as an anonymous module.
        define( [ "../widgets/datepicker" ], factory );
    } else {

        // Browser globals
        factory( jQuery.datepicker );
    }
}( function( datepicker ) {

datepicker.regional[ "zh-CN" ] = {
    closeText: "关闭",
    prevText: "&#x3C;上月",
    nextText: "下月&#x3E;",
    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" };
datepicker.setDefaults( datepicker.regional[ "zh-CN" ] );

return datepicker.regional[ "zh-CN" ];

} ) );

使用本地化配置文件示例：

<html lang="zh">
