bootstrap-datepicker 是一個非常優秀的時間選擇外掛，預設是英文顯示日期的，通過下面幾個小修改讓其支援預設中文

1、首先將 bootstrap-datepicker.js 另存為 utf-8 格式儲存

2、增加 cn 語言選項

    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"
        },
        cn: {
            days: ["週日", "週一", "週二", "週三", "週四", "週五", "週六", "週日"],
            daysShort: ["日", "一", "二", "三", "四", "五", "六", "七"],
            daysMin: ["日", "一", "二", "三", "四", "五", "六", "七"],
            months: ["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"],
            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: "清除"
 

        }
    };

紅色部分為增加的語言選項

3、修改預設引數，預設語言為 cn

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

紅色部分為修改的預設語言

至此完成預設中文的修改，效果如下圖：
