Pikaday ======== ### A refreshing JavaScript Datepicker * Lightweight (less than 5kb minified and gzipped) * No dependencies (but plays well with [Moment.js][moment] * Modular CSS classes for easy styling [**Try Pikaday Demo →**][Pikaday] ![Pikaday Screenshot][screenshot] **Production ready?** Since version 1.0.0 Pikaday is stable and used in production. If you do however find bugs or have feature requests please submit them to the [GitHub issue tracker][issues]. Also see the [changelog](CHANGELOG.md) ## Usage **Pikaday** can be bound to an input field: ```html <input type="text" id="datepicker"> ``` Add the JavaScript to the end of your document: ```html <script src="pikaday.js"></script> <script> var picker = new Pikaday({ field: document.getElementById('datepicker') }); </script> ``` If you're using **jQuery** make sure to pass only the first element: ```javascript var picker = new Pikaday({ field: $('#datepicker')[0] }); ``` If the Pikaday instance is not bound to a field you can append the element anywhere: ```javascript var field = document.getElementById('datepicker'); var picker = new Pikaday({ onSelect: function(date) { field.value = picker.toString(); } }); field.parentNode.insertBefore(picker.el, field.nextSibling); ``` For advanced formatting load [Moment.js][moment] prior to Pikaday: See the [moment.js example][] for a full version. ```html <input type="text" id="datepicker" value="9 Oct 2014"> <script src="moment.js"></script> <script src="pikaday.js"></script> <script> var picker = new Pikaday({ field: document.getElementById('datepicker'), format: 'D MMM YYYY', onSelect: function() { console.log(this.getMoment().format('Do MMMM YYYY')); } }); </script> ``` ### Configuration 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') * `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][moment] 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()`) * `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`) * `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`) * `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 * `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. ```html <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> <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! $('.datepicker').eq(0).pikaday('show').pikaday('gotoYear', 2042); </script> ``` ## AMD support If you use a modular script loader than Pikaday is not bound to the global object and will fit nicely in your build process. You can require Pikaday just like any other module. See the [AMD example][] for a full version. ```javascript require(['pikaday'], function(Pikaday) { var picker = new Pikaday({ field: document.getElementById('datepicker') }); }); ``` The same applies for the jQuery plugin mentioned above. See the [jQuery AMD example][] for a full version. ```javascript require(['jquery', 'pikaday.jquery'], function($) { $('#datepicker').pikaday(); }); ``` ## CommonJS module support If you use a CommonJS compatible environment you can use the require function to import Pikaday. ```javascript var pikaday = require('pikaday'); ``` When you bundle all your required modules with [Browserify][browserify] and you don't use [Moment.js][moment] 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][gem]. ## Methods You can control the date picker after creation: ```javascript var picker = new Pikaday({ field: document.getElementById('datepicker') }); ``` ### Get and set date `picker.toString('YYYY-MM-DD')` Returns the selected date in a string format. If [Moment.js][moment] exists (recommended) then Pikaday can return any format that Moment understands, otherwise you're stuck with JavaScript's default. `picker.getDate()` Returns a basic JavaScript `Date` object of the selected day, or `null` if no selection. `picker.setDate('2015-01-01')` 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. `picker.getMoment()` Returns a [Moment.js][moment] 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][moment] 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][mdn_date]). `picker.gotoToday()` Shortcut for `picker.gotoDate(new Date())` `picker.gotoMonth(2)` 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). `picker.gotoYear()` Change the year being viewed. `picker.setMinDate()` Update the minimum/earliest date that can be selected. `picker.setMaxDate()` Update the maximum/latest date that can be selected. ### Show and hide datepicker `picker.isVisible()` Returns `true` or `false`. `picker.show()` Make the picker visible. `picker.adjustPosition()` Recalculate and change the position of the picker. `picker.hide()` Hide the picker making it invisible. `picker.destroy()`
