javascript API for generating QR codes

问题:

I am looking for a javascript API for generating QR codes (name, address and such) and outputting them in a printable format (png/jpeg/pdf). This seems to me to be something others before must have had a need for.

回答1:

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

回答2:

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"});

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
