React/JSX Usage

  { Tzolkin } = require('tzolkin')

  render: => {
    return (
      <div>
        <Tzolkin type="datetime">
          <input defaultValue="3/09/2018" type="input" />
        </Tzolkin>
      </div>
    )
  }

Standard JavaScript or jQuery Usage

HTML:

  <input type='text' name='date' class='select-datetime' />

To prevent any browser Date/Time picker UI, use a standard text input vs date, time or datetime.

TzolkinPlugin v1.x.x JS:

  { TzolkinPlugin } = require('tzolkin');

  TzolkinPlugin.create({
    type: 'datetime',
    input: '.select-datetime'
  })

TzolkinPlugin v2.x.x JS:

  { TzolkinPlugin } = require('tzolkin');

  tz = new TzolkinPlugin().create({
    type: 'datetime',
    input: '.select-datetime'
  })

  // if you need to:
  tz.close()

Multiple Instances

  <label>Date</label>
  <input type='text' name='date' class='select-datetime' />

  <label>Time</label>
  <input type='text' name='time' class='select-datetime' />

If there are multiple inputs which need to use Tzolkin then set input key equal to a JavaScript selected element or have different classes for each and pass just the CSS class as a string.

  { TzolkinPlugin } = require('tzolkin');

  dt_input = document.querySelectorAll('.select-datetime')[0];
  // or $('.select-datetime')[0]
  tm_input = document.querySelectorAll('.select-datetime')[1];
  // or $('.select-datetime')[1]

  TzolkinPlugin.create({ type: 'date', input:  dt_input});
  TzolkinPlugin.create({ type: 'time', input:  tm_input});

Disabling Dates and Times

Tzolkin allows selected days of week, months, dates, hours and/or years to disable from user selection. This option expects a JavaScript object with one or more of the following keys.

key	description
years	a list of years where every day will be disabled
months	a list of months where every day will be disabled
dates	a list of individual dates to be disabled across all months
days	all dates that fall under selected days (Monday, Tuesday, etc)
hours	a list of hours to be disable from selection

Example:

  let disable = {
    years: [2010, 2012, 2014],
    months: ["February", "May"],
    dates: [1, 5, 24],
    days: ["Sunday", "Saturday"],
    hours: ["11am", "12am", "1pm"]
  }

  <Tzolkin type="datetime" disable={disable}>
    <input defaultValue="3/09/2018 9:30 am" type="input"/>
  </Tzolkin>

Callbacks

Tzolkin allows for 3 callbacks occurring at different points in the lifecycle of the date/time picker.

callback	when
onOpen	during componentDidMount called on picker component
onSelect	called immediately after a date or time has been clicked
onClose	during componentWillUnmount called on picker component

Example:

  Tzolkin.create({
    type: 'datetime',
    input: '.select-datetime',

    onOpen: (date, picker_el, input_el) => {
      console.log("Opening date/time picker");
      console.log(date);
      // ... do something cool ...
    },

    onSelect: (date, picker_el, input_el) => {
      alert("You picked" + date);
      // ... do something EVEN cooler ...
    },

    onClose: (date, picker_el, input_el) => {
      console.log("Closing date/time picker")
      // ... do something mildly entertaining ...
    }
  })
