You can use this lib .

Just follow this idea. 

 function qrCodeExample(url) {
  var qrcode = new QRCode(document.getElementById("qrcode"), {
    text: url,
    width: 70,
    height: 70,
    colorDark: "#000000",
    colorLight: "#ffffff",
    correctLevel: QRCode.CorrectLevel.H
  });
}

After it's load, for example, it's a < div > the qrcode content: 

    <div id="qrcode" align="center">
     </div>
