Usage

html-file config

Link to the Pikaday-js library (with it's css file) and the optional but highly advisable Moment.js library (for advanced date formating) in your index.html-file:

<link rel="stylesheet" href="https://github.com/simon-void/pikaday_datepicker/blob/master/pikaday.css">
<script src="https://github.com/simon-void/pikaday_datepicker/raw/master/moment.js"></script>
<script src="https://github.com/simon-void/pikaday_datepicker/raw/master/pikaday.js"></script>

Download a local copy of those libs, put them in or under the directory your index.html file is in, an link accordingly.

dart-file usage

Check out the example under web.

Import and use PikadayParams and upgradeInputToDatepicker(...) into your dart code:

import 'dart:html';
import 'package:intl/intl.dart';
import 'package:pikaday_datepicker/pikaday_datepicker.dart';

void main() {
  final inputElem = new InputElement() ..placeholder="select a day";
  final outputElem = new DivElement();

  final params = new PikadayParams()
    ..defaultDay = new DateTime(2015, 2, 1)
    ..format="DD-MM-YYYY"
    ..firstDay="1"
    ..minDate="2010-1-1"
    ..maxDate="2025-12-31"
    ..showDayOnInit="false";

  final dayFormatter = new DateFormat('MMM dd, yyyy');
  updateOutput(DateTime selectedDay){
    outputElem.text = "selectedDay: ${dayFormatter.format(selectedDay)}";
  }

  // make the input a pikaday-datepicker
  upgradeInputToDatepicker(inputElem, updateOutput, params);

  // wire the elements to the page
  final appDiv = querySelector("#datepickerShowcase");
  appDiv.text = "";
  appDiv.children
    ..add(inputElem)
    ..add(outputElem);
}

Configuration

PikadayParams has many useful options, which can be provided as instance of type String or their real type (int/bool/DateTime with format yyyy-mm-dd):

defaultDay doesn't what it sounds like
showDayOnInit display defaultDay in inputfield on startup, otherwise show no date, but use defaultDay when opening the picker-dialog
bound automatically show/hide the datepicker on input 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 (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)
format the output format used within the input element (requires Moment.js for custom formatting)
formatStrict the default flag for moment's strict date parsing (requires Moment.js for custom formatting)
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
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 example on Pikaday)
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: true)
numberOfMonths number of visible calendars
mainCalendarIsLeft when numberOfMonths is used, this will help you to choose where the main calendar will be (default true/left, can be set to false/right). Only used for the first display or when a selected date is not already visible
theme define a classname that can be used as a hook for styling different themes (default null)

Common problems

console error msg: constructor not a function

The Dart-Wrapper can't access the Pikaday-JS-constructor. You probably forgot to link to the js-lib itself in index.html:

<link rel="stylesheet" href="https://github.com/simon-void/pikaday_datepicker/blob/master/pikaday.css">
<script src="https://github.com/simon-void/pikaday_datepicker/raw/master/moment.js"></script>
<script src="https://github.com/simon-void/pikaday_datepicker/raw/master/pikaday.js"></script>
