Using QrCode Generator plugin

The Plugin will be in charge of displaying the generated QRCode, so you should at least set a size of 128x128px if you want to display a readable QRCode.

Now we will learn how to call the QRCode generator Plugin with a text we want to convert to QRCode.

The QRCode Plugin implements a JavaScript object named  nodeQrcode.
It exposes a single function named  drawQR.

In order to convert a text to QRCode, you just have to call this function, for example:

nodeQrcode.drawQR(elt,v);

Elt is a reference to a js element ( for instance: var elt=document.getElementById(“myID"); ), and v is the text to convert.
