JavaScript Examples

The following examples demonstrate usage of the JavaScript API's for Coral.Calendar.

The following JavaScript manually initializes the component on page initialization and adds it to the DOM. 

<script>
$(document).ready(function() {
  var calendar = new Coral.Calendar().set({
    id: 'myCalendar',
    min: new Date(2014,8,1),
    max: new Date(2014,11,31),
    valueAsDate: new Date(2014,9,23)
  });
  document.getElementById('constructorExample').appendChild(calendar);
})
</script>
<coral-calendar class="coral3-Calendar" valueformat="YYYY-MM-DD" role="region" id="myCalendar"><input handle="input" type="hidden" name="" value="2014-10-23">
<div class=" coral3-Calendar-calendarHeader">
<div handle="heading" class=" coral-Heading coral-Heading--2" id="coral-id-0" role="heading" aria-live="assertive" aria-atomic="true"></div>
<button is="coral-button" class="coral3-Button coral3-Calendar-prevMonth coral3-Button--minimal" size="M" variant="minimal" type="button" handle="prev" icon="chevronLeft" iconsize="XS" aria-label="Previous" title="Previous"><coral-icon class="coral3-Icon" icon="chevronLeft" size="XS"></coral-icon><coral-button-label></coral-button-label></button>
<button is="coral-button" class="coral3-Button coral3-Calendar-nextMonth coral3-Button--minimal" size="M" variant="minimal" type="button" handle="next" icon="chevronRight" iconsize="XS" aria-label="Next" title="Next"><coral-icon class="coral3-Icon" icon="chevronRight" size="XS"></coral-icon><coral-button-label></coral-button-label></button>
</div>
<div class=" coral3-Calendar-calendarBody" handle="body" role="grid" tabindex="0" aria-readonly="true"></div></coral-calendar>

Getting the value

The following will display the above component's value in an alert. 
<script>
function displayValue() {
  var value = document.querySelector('#myCalendar').value;
  alert('The value is ' + value + '.');
}
</script>

Setting the value

The following will set the above component value to December 5th 2014. 
<script>
  function setValue() {
    var calendar = document.querySelector('#myCalendar');
    calendar.valueAsDate = new Date(2014,11,5);
  }
</script>

Responding to user interaction

The following example shows how to detect changes performed by the user. 
<script>
  $(document).ready(function () {
    var eventLog = $('#calendarLog');
    document.querySelector('#myCalendar').on('change', function(event) {
      var value = event.target.value;
      eventLog.log('Calendar new value: ' + value);
    });
  });
</script>

Working with locales

The following example sets up the component to use the appropriate date formatting for the specified page locale (e.g. <html lang="fr-FR">). Requires moment-with-locales.js. 

<script>
$(document).ready(function() {
  moment.locale(document.documentElement.lang || window.navigator.language || 'en');
  var calendar = new Coral.Calendar().set({
    id: 'myCalendar',
    min: new Date(2014,8,1),
    max: new Date(2014,11,31),
    valueAsDate: new Date(2014,9,23),
    startDay: moment.localeData().firstDayOfWeek()
  });
})
</script>

Note: moment-with-locales.js provides support to close to 100 locales. If maintaining minimal footprint is critical to your product, it's possible to generate a custom version (moment-with-locales.custom.js) that limits support to a set of languages you can specify.
