                JSQrcode library tutorial
              
          
    Introduction

This tutorial is a step by step guide on how to use the javascript QR Code scanner on a webcam video stream in browser. Some people reported experiencing problems including it in their own projets so I guess a tutorial might help others.
Step 1: Include library in <head> section

<html lang="en">
  <head>
    <script type="text/javascript" src="grid.js"></script>
    <script type="text/javascript" src="version.js"></script>
    <script type="text/javascript" src="detector.js"></script>
