Infinite Scrolling Date Picker UI With Pure JavaScript

Preview:

Description:

A pure JavaScript date picker component that enables the user to select a date from an infinite scrolling calendar UI.

How to use it:

Load the main style sheet ‘styles.css’ to style the date picker.

<link rel="stylesheet" href="styles.css">

Create a regular text field to accept the date input.

<input name="date" value="2017-05-31"/>

Load the JavaScript file ‘datepicker.js’ right before the closing body tag.

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

Initialize the date picker and we’re done.

var input = document.querySelector('input[name="date"]');
var picker = datepicker(input);

Event listeners.

input.addEventListener('change', () => {
  console.log('change', input.value);
});
input.addEventListener('input', () => {
  console.log('input', input.value);
});

All default options to customize the date picker.

var picker = datepicker(input,{
    animation: {
        duration: 200,
        easing:   'cubic-bezier(0.86, 0, 0.07, 1)'
