Description - View Demo

This is a cross platform jQuery library to create a QRcode reader for HTML5 compatible browser. It comes with option to scan QR Code, Stop scanning, Switch Camera and get info on camera.

How to use?

• Add an element you want to use as placeholder for QR Code scanner

<div id="reader"></div>

• Add jQuery library, jsqrcode-combined.js and html5-qrcode.js (or their minified versions).

<script scr="./jqeury.js"></script>
<script scr="./jsqrcode-combined.js"></script>
<script scr="./html5-qrcode.js"></script>

• To start the camera and start reading QR code

  $('#reader').html5_qrcode(function(data){
    /* do something when code is read */
  }, function(error){
    /* show read errors */
  }, function(videoError){
    /* the video stream could be opened */
  });

Note: you can also pass fourth parameter which is the camera index to use. If the device has 2 cameras and fourth parameter is 1 so 2nd camera will be used. If a wrong number is passed default camera shall be used.

• To stop using camera and thus stop scanning, call

  $('#reader').html5_qrcode_stop();

• To switch camera, call

  $('#reader').html5_qrcode_changeCamera();

• To get no of cameras, call

  var cameraCount = $("#reader").html5_qrcode_cameraCount();
