Reading Barcode From An Image Using Javascript

I need a javascript code that will read/ extract barcode from an image. for example, the image may be embedded in a web page and i wan to pass the image to the Javascript function

Solution 1:

There is QuaggaJS library (open source) for reading barcodes, all done in JavaScript.

It currently supports EAN, CODE 128, CODE 39, EAN 8, UPC-A, UPC-C, and CODABAR

I suspect it will meet your needs.

Update: 2021-August

Looks like the original QuaggaJS is no longer actively maintained.

Quagga2 is active and continues the goals of the original.

(thanks @bertasoft for the tip!)
