Lightweight Input Autocomplete with Vanilla JavaScript – Barq

Barq is a lightweight JavaScript library that turns default select list into a text filed that has regex powered autocomplete enabled.

How to use it:

Load the barq.css in the header for basic styles.

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

Load the barq.js at the bottom of the document.

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

Insert a select list into your document.

<select id="demo">
  <option>Select an airport</option>
  <option value="1">Aalborg, Denmark (AAL)</option>
  <option value="2">Aalesund, Norway (AES)</option>
  <option value="ds" SELECTED>Aarhus, Denmark – Bus service (ZID)</option>
  <option value="4">Aarhus, Denmark – Tirstrup (AAR)</option>

  <option value="">Abadan, Iran (ABD)</option>
  <option value="">Abakan, Russia (ABA)</option>
