Downloading a qrcode.js-generated QR code

Asked 2021-Jun-22 at 06:27

I've searched the web countless times trying to find a way to solve this but I've come up empty-handed every time. I have been using qrcode.js to generate QR codes for a website, but I haven't figured out how to download the image once it's been generated. The code I use to generate the QR code looks like this:

The image is generated through the plugin and takes a moment to render, so the method needs to be done with setTimeout. After that, we grab the src of the image and apply it to a download link (a link that has the attribute download in it)

Note this won't work in the snippet sandbox, but it's been tested on a normal web page and works great.

Are you using davidshimjs/qrcodejs ?

When you're doing new QRCode(document.getElementById("qrcode"), url);, the lib expect document.getElementById("qrcode") to return the elem. In the html code you provided, you don't seems to have that element.

You can try to add

in your html file to display the output QR code

ANSWER

Answered 2021-Apr-08 at 00:51

The reason why you get an empty string back, even though you can see the src value in your dev tools, is that it takes a very short amount of time to generate the QR-Code.

So var base64 = document.getElementById("qr_neu").src;is called before the QR-Code is generated.

Here is a relevant issues on the qrcode.js repository: https://github.com/davidshimjs/qrcodejs/issues/160.

Here is the solution adapted to your code:
