Issue #3262470 by gaurav.kapoor: Improve internal documentation, description...

Pikaday Calendar

****************

Add the JavaScript to the end of your document:

<script src="pikaday.js"></script>

<script>

    var picker = new Pikaday({ field: document.getElementById('datepicker') });

</script>

If you're using jQuery make sure to pass only the first element:

var picker = new Pikaday({ field: $('#datepicker')[0] });

If the Pikaday instance is not bound to a field you can append the element

anywhere:

var field = document.getElementById('datepicker');

var picker = new Pikaday({

    onSelect: function(date) {

        field.value = picker.toString();

    }

});

field.parentNode.insertBefore(picker.el, field.nextSibling);
