bootstrap-datepicker 插件修改为默认中文

datepicker插件默认为英文，而且格式为：mm/dd/yyyy这种情况，看起来不怎么直观。

修改目标：

1、默认显示为中文  

2、格式为：yyyy年mm月dd日

 

需要修改两个地方：

1、更改datas对象， 增加zh-cn语言选项；参见源代码的1419行

var dates = $.fn.datepicker.dates = {        en: {            days: ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"],            daysShort: ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],            daysMin: ["Su", "Mo", "Tu", "We", "Th", "Fr", "Sa", "Su"],            months: ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"],            monthsShort: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],            today: "Today",            clear: "Clear"        },        "zh-cn":{            days: ["星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期日"],            daysShort: ["周日", "周一", "周二", "周三", "周四", "周五", "周六", "周日"],            daysMin: ["日", "一", "二", "三", "四", "五", "六", "日"],            months: ["一月份", "二月份", "三月份", "四月份", "五月份", "六月份", "七月份", "八月份", "九月份", "十月份", "十一月份", "十二月份"],            monthsShort: ["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"],            today: "今天",            clear: "清空"        }    };
    
     红色部分为新增部分。

        2、修改默认参数，即defaults对象。       

var defaults = $.fn.datepicker.defaults = {        autoclose: false,        beforeShowDay: $.noop,        calendarWeeks: false,        clearBtn: false,        daysOfWeekDisabled: [],        endDate: Infinity,        forceParse: true,        format: 'yyyy年mm月dd日',        keyboardNavigation: true,        language: 'zh-cn',        minViewMode: 0,        multidate: false,        multidateSeparator: ',',        orientation: "auto",        rtl: false,        startDate: -Infinity,        startView: 0,        todayBtn: false,        todayHighlight: false,        weekStart: 0    };

       3、效果如下
