Answer 2

Maksym's solution is better than Google's library because it runs at local does not need to call Google API. also if you don't use jQuery, you can use this one at https://github.com/amanuel/JS-HTML5-QRCode-Generator

Google has a QR code generator as part of their Chart Tools that you can use here.

Answer 5

jquery-qrcode jQuery plugin also generates QR code using HTML5 canvas element or HTML table, if canvas is not supported.

https://github.com/jeromeetienne/jquery-qrcode

$('#test').qrcode({
    width: 120,
    height: 120, 
    text: "https://github.com/jeromeetienne/jquery-qrcode"});
