Pikaday.js 是一个 JavaScript 日期选择器,它不依赖于任何第三方 JavaScript 库,并且文件大小小于 5K,但是功能却一点不弱,可以进行很多高级定制。并且样式可以根据 CSS 进行更改选择器的设计,当然默认的样式已经非常不错了。


  • 重量轻插件(小于5kb压缩和gzip)
  • 没有依赖(如果需要格式化日期,可能需要使用到 Moment.js
  • 模块化CSS类,方便自定义样式。



<input type="text" id="datepicker">

在页脚加载 Pikaday 的 JavaScript 库和 CSS 文件,并调用 Pikaday:

<link rel="stylesheet" href="pikaday.css">
<script src="pikaday.js"></script>
    var picker = new Pikaday({ field: document.getElementById('datepicker') });

如果网页已经加载了 jQuery 库,其中调用代码可以改成下面更简洁的方式:

var picker = new Pikaday({ field: $('#datepicker')[0] });


var field = document.getElementById('datepicker');
var picker = new Pikaday({
    onSelect: function(date) {
        field.value = picker.toString();
field.parentNode.insertBefore(picker.el, field.nextSibling);

通过 Moment.js 高级格式化Pikaday.js日期的显示格式,你可以点击这里查看更多 Moment.js 的示例。

<input type="text" id="datepicker" value="9 Oct 2014">

<script src="moment.js"></script>
<script src="pikaday.js"></script>
    var picker = new Pikaday({
        field: document.getElementById('datepicker'),
        format: 'D MMM YYYY',
        onSelect: function() {
            console.log(this.getMoment().format('Do MMMM YYYY'));


As the examples demonstrate above Pikaday has many useful options:

  • field bind the datepicker to a form field
  • trigger use a different element to trigger opening the datepicker, see trigger example (default to field)
  • bound automatically show/hide the datepicker on field focus (default true if field is set)
  • position preferred position of the datepicker relative to the form field, e.g.: top right, bottom right Note: automatic adjustment may occur to avoid datepicker from being displayed outside the viewport, see positions example (default to 'bottom left')
  • reposition can be set to false to not reposition datepicker within the viewport, forcing it to take the configured position (default: true)
  • container DOM node to render calendar into, see container example (default: undefined)
  • format the default output format for .toString() and field value (requires Moment.js for custom formatting)
  • formatStrict the default flag for moment's strict date parsing (requires Moment.js for custom formatting)
  • defaultDate the initial date to view when first opened
  • setDefaultDate make the defaultDate the initial selected value
  • firstDay first day of the week (0: Sunday, 1: Monday, etc)
  • minDate the minimum/earliest date that can be selected (this should be a native Date object - e.g. new Date() or moment().toDate())
  • maxDate the maximum/latest date that can be selected (this should be a native Date object - e.g. new Date() or moment().toDate())
  • disableWeekends disallow selection of Saturdays or Sundays
  • disableDayFn callback function that gets passed a Date object for each day in view. Should return true to disable selection of that day.
  • yearRange number of years either side (e.g. 10) or array of upper/lower range (e.g. [1900,2015])
  • showWeekNumber show the ISO week number at the head of the row (default false)
  • pickWholeWeek select a whole week instead of a day (default false)
  • isRTL reverse the calendar for right-to-left languages
  • i18n language defaults for month and weekday names (see internationalization below)
  • yearSuffix additional text to append to the year in the title
  • showMonthAfterYear render the month after year in the title (default false)
  • showDaysInNextAndPreviousMonths render days of the calendar grid that fall in the next or previous months to the current month instead of rendering an empty table cell (default: false)
  • numberOfMonths number of visible calendars
  • mainCalendar when numberOfMonths is used, this will help you to choose where the main calendar will be (default left, can be set to right). Only used for the first display or when a selected date is not already visible
  • events array of dates that you would like to differentiate from regular days (e.g. ['Sat Jun 28 2017', 'Sun Jun 29 2017', 'Tue Jul 01 2017',])
  • theme define a classname that can be used as a hook for styling different themes, see theme example (default null)
  • blurFieldOnSelect defines if the field is blurred when a date is selected (default true)
  • onSelect callback function for when a date is selected
  • onOpen callback function for when the picker becomes visible
  • onClose callback function for when the picker is hidden
  • onDraw callback function for when the picker draws a new month

jQuery Plugin

The normal version of Pikaday does not require jQuery, however there is a jQuery plugin if that floats your boat (see plugins/pikaday.jquery.js in the repository). This version requires jQuery, naturally, and can be used like other plugins: See the jQuery example for a full version.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="pikaday.js"></script>
<script src="plugins/pikaday.jquery.js"></script>

// activate datepickers for all elements with a class of `datepicker`
$('.datepicker').pikaday({ firstDay: 1 });

// chain a few methods for the first datepicker, jQuery style!
$('.datepicker').eq(0).pikaday('show').pikaday('gotoYear', 2042);


AMD support

If you use a modular script loader than Pikaday is not bound to the global object and will fit nicely in your build process. You can require Pikaday just like any other module. See the AMD example for a full version.

require(['pikaday'], function(Pikaday) {
    var picker = new Pikaday({ field: document.getElementById('datepicker') });

The same applies for the jQuery plugin mentioned above. See the jQuery AMD example for a full version.

require(['jquery', 'pikaday.jquery'], function($) {

CommonJS module support

If you use a CommonJS compatible environment you can use the require function to import Pikaday.

var pikaday = require('pikaday');

When you bundle all your required modules with Browserify and you don't use Moment.js specify the ignore option:

browserify main.js -o bundle.js -i moment

Ruby on Rails

If you're using Ruby on Rails, make sure to check out the Pikaday gem.


You can control the date picker after creation:

var picker = new Pikaday({ field: document.getElementById('datepicker') });

Get and set date


Returns the selected date in a string format. If Moment.js exists (recommended) then Pikaday can return any format that Moment understands, otherwise you're stuck with JavaScript's default.


Returns a basic JavaScript Date object of the selected day, or null if no selection.


Set the current selection. This will be restricted within the bounds of minDate and maxDate options if they're specified. You can optionally pass a boolean as the second parameter to prevent triggering of the onSelect callback (true), allowing the date to be set silently.


Returns a Moment.js object for the selected date (Moment must be loaded before Pikaday).

picker.setMoment(moment('14th February 2014', 'DDo MMMM YYYY'))

Set the current selection with a Moment.js object (see setDate for details).

Change current view

picker.gotoDate(new Date(2014, 1))

Change the current view to see a specific date. This example will jump to February 2014 (month is a zero-based index).


Shortcut for picker.gotoDate(new Date())


Change the current view by month (0: January, 1: Februrary, etc).

picker.nextMonth() picker.prevMonth()

Go to the next or previous month (this will change year if necessary).


Change the year being viewed.


Update the minimum/earliest date that can be selected.


Update the maximum/latest date that can be selected.


Update the range start date. For using two Pikaday instances to select a date range.


Update the range end date. For using two Pikaday instances to select a date range.

Show and hide datepicker


Returns true or false.


Make the picker visible.


Recalculate and change the position of the picker.


Hide the picker making it invisible.


Hide the picker and remove all event listeners — no going back!


The default i18n configuration format looks like this:

i18n: {
    previousMonth : 'Previous Month',
    nextMonth     : 'Next Month',
    months        : ['January','February','March','April','May','June','July','August','September','October','November','December'],
    weekdays      : ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],
    weekdaysShort : ['Sun','Mon','Tue','Wed','Thu','Fri','Sat']

You must provide 12 months and 7 weekdays (with abbreviations). Always specify weekdays in this order with Sunday first. You can change the firstDay option to reorder if necessary (0: Sunday, 1: Monday, etc). You can also set isRTL to true for languages that are read right-to-left.
