Datepicker.js

See the demo here

Quick Start

Include the files

<!-- or another theme from `dist/css` -->
<link rel="stylesheet" href="datepicker.material.css">
<script src="datepicker.js"></script>

Distiguish the Datepicker

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

Initialize Datepicker.js

var datepicker = new Datepicker('#datepicker');

Basic Usage

Call the constructor with an element or selector. Passing a selector other than an ID will return an array of initialized Datepickers matching the selector.

/* All valid */

new Datepicker(document.getElementById('datepicker'));
// => Datepicker

new Datepicker('#datepicker');
// => Datepicker

new Datepicker('.datepicker');
// => [Datepicker, ...]

Pass an object of options to customize the Datepicker during initialization. Data attributes can also be used to set options.

<input type="hidden" id="datepicker" data-inline="true"/>

var datepicker = new Datepicker('#datepicker', {
  multiple: true,
  inline: false
});

datepicker.get('inline');
// => true

datepicker.get('multiple');
// => true

Options

Inline Datepicker

inline: (true|false)

Best used with hidden inputs. Enabling this will render the Datepicker inline with the input and prevent show/hide functionality.

Multiple Dates

multiple: (true|false)

Enables the ability for multiple dates to be selected. Clicking and dragging selects/deselects a range of dates.

Ranged Selection

ranged: (true|false)

Forces the selection to a range of dates. Subsequent clicks and dragging select a new range.

Time Picker

time: (true|false|"ranged")

Enables a single time picker for non-ranged Datepickers when true. For ranged Datepickers, or when time is "ranged", two time pickers are rendered: "start" and "end".

Additional Options

openOn: (Date|"first"|"last"|"today") Default place the Datepicker will open to. A specified date, today, or the first/last date within the selected dates. Default "first".

min/max: (Date|false) Minimum and maximum dates available to select from. Default false.

within: ([Date...]|false) If provided, only dates within this array will be allowed. Default false.

without: ([Date...]|false) If provided, dates within this array will be excluded. Default false.

yearRange: (Integer) How many years forward & backward from the active year the Datepicker will display in the year dropdown menu. Default 5.

weekStart: (Integer) Index of the day of the week to start on, 0-6. 0 == Sunday, 1 == Monday, etc. Default 0.

defaultTime: (Object|Array) Default time when the time option is enabled. Given an array of [hours, minutes], will set both the start and end default times. An object consisting of start and end arrays will set them individually.
Default { start: [0, 0], end: [12, 0] }.

separator: (String) The separator used when serializing multiple dates. Default ",".

serialize: ((Date) => String) Transforms a date into a string to be set as the value of the input.

deserialize: ((String) => Date) Parses a string into a date. Called whenever a date string is used instead of a date object.

Callbacks

toValue: (([Date...]) => String) Transforms the current selected dates to a string used to set the value of the input element.

fromValue: ((String) => [Date...]) Parses the value of the input into an array of selected dates.

onInit: ((Element)) Called after initialization with the original input element as the only parameter.

onChange: ((Date|[Date...])) Called whenever the selected dates change or when the time or time range is updated. The currently selected date(s) are passed; start and end times are set on the respective start and end dates.

onRender: ((Element)) Called whenever the Datepicker is rendered. The element passed is the first child from the resulting templates.

Advanced

Localization

i18n:

months: An array of month names. 0 == January, 12 == December, etc.
weekdays: An array of weekday names. 0 == Sunday, 1 == Monday, etc.
time: An array of labels for the time picker. The first, for non-ranged time pickers. The second, for the starting time. And the third, for the ending time.

Customization

classNames:

{
  node:        'datepicker',
  wrapper:     'datepicker__wrapper',
  inline:      'is-inline',
  selected:    'is-selected',
  disabled:    'is-disabled',
  highlighted: 'is-highlighted',
  otherMonth:  'is-otherMonth',
  weekend:     'is-weekend',
  today:       'is-today'
}

templates: Used for rendering the Datepicker. Utilizes John Resig's micro-templating. A number of properties are available within each template's context.

container: Top-level element within the wrapper.
header: Header navigation for any given month.
timepicker: Rendered when the time picker is enabled.
calendar: The actual calendar for any given month.
day: An individual day within the calendar.

See the default templates for reference. For a list of available properties within each template context, also see the default templates.

Methods

datepiker.set(option[, value])

@param {String|Object} option
@param {Mixed} value

Update an option on the Datepicker. Pass an object as the only argument to update multiple options at once.

datepicker.get(option[, ...])

@param {String} option
@return {Mixed}

Retrieve the value of an option from the Datepicker. Pass multiple options as additional arguments to receive an object of options in return.

datepicker.open([openOn])

@param {Date|String} openOn

Open the Datepicker to the date specified by openOn. If not specified, will default to the value of the openOn option. See above for possible values.

datepicker.show()

Displays and positions the Datepicker. If inline is true, this method does nothing.

datepicker.hide()

Hides the Datepicker. If inline is true, this method does nothing.

datepicker.toggle()

Toggles the open() and hide() methods based on whether the Datepicker is open or not.

datepicker.next([skip])
datepicker.prev([skip])

@param {Integer} skip

Advance the Datepicker forward/backward by a month. skip will advance the Datepicker by the specified number.

datepicker.goToDate(date)

@param {Date} date
