How to use it:

Add references to the Hello Week’s JavaScript and CSS files.

<link href="dist/helloweek.css" rel="stylesheet">
<script src="dist/helloweek.min.js"></script>

The basic html structure for the calendar.

<div class="hello-week">
  <div class="hello-week__header">
    <button class="btn demo-prev">◀</button>
    <div class="hello-week__label"></div>
    <button class="btn demo-next">▶</button>
  </div>
  <div class="hello-week__week"></div>
  <div class="hello-week__month"></div>
</div>

Initialize the calendar with default settings.

const myCalendar = new HelloWeek();

Enable the prev/next buttons.

const prev = document.querySelector('.demo-prev');
const next = document.querySelector('.demo-next');

Get current, picked, and last picked dates.

<p><strong>Today:</strong> </p>
<ul class="demo-today"><span>n/a</span></ul>
<p><strong>Last Picked Day:</strong></p>
<ul class="demo-last"><span>n/a</span></ul>
<p><strong>Picked Days:</strong></p>
<ul class="demo-picked"><span>n/a</span></ul>

const today = document.querySelector('.demo-today');
const picked = document.querySelector('.demo-picked');
const last = document.querySelector('.demo-last');
function updateInfo() {
  if (this.today) {
    today.innerHTML = '';
    var li = document.createElement('li');
    li.innerHTML = this.today;
    today.appendChild(li);
  }
  if (this.lastSelectedDay) {
    picked.innerHTML = '';
    for (days of this.selectedDays) {
      var li = document.createElement('li');
      li.innerHTML = days;
      picked.appendChild(li);
    }
    last.innerHTML = '';
    var li = document.createElement('li');
    li.innerHTML = this.lastSelectedDay;
    last.appendChild(li);
  }
}
const myCalendar = new HelloWeek({
  onLoad: updateInfo,
  onChange: updateInfo,
  onSelect: updateInfo
});

Default plugin settings and callback functions to customize the calendar.

const myCalendar = new HelloWeek({
      selector: '.hello-week',
      lang: 'en',
      langFolder: './dist/langs/',
      format: 'dd/mm/yyyy',
      weekShort: true,
      monthShort: false,
      multiplePick: false,
      defaultDate: false,
      todayHighlight: true,
      daysSelected: null // ['2019-02-26', '2019-03-01', '2019-03-02', '2019-03-03']
      disablePastDays: false,
      disabledDaysOfWeek: false,
      disableDates: false,
      weekStart: 0, // 0 (Sunday) to 6 (Saturday).
      daysHighlight: false,
      range: false,
      rtl: false,
      locked: false
      minDate: false,
      maxDate: false,
      nav: ['◀', '▶'],
      onLoad: () => { /** callback function */ },
      onChange: () => { /** callback function */ },
      onSelect: () => { /** callback function */ },
      onClear: () => { /** callback function */ },
      beforeCreateDay: (node) => { /** callback function */ },
});
