jquery-qrcode is a client‑side QR code generator built as a jQuery plugin. It creates QR code images entirely in the browser without sending data to an external service, making it suitable for offline usage and reducing network dependencies. The plugin accepts input data — such as a string or URL — and produces a QR code that can be rendered as an image in any selected DOM element.
Because it is a jQuery plugin, jquery-qrcode integrates naturally into existing jQuery‑based web projects using the usual plugin API. The generated QR code can be customised with adjustable size, error correction level, and foreground and background colours, all handled locally by the JavaScript library. This self‑contained approach eliminates the need for a server‑side QR code API and allows the code to work offline.
