reading barcode from an image using javascript

I need a javascript cod开发者_StackOverflow社区e 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.

The function should read/parse the image and extract the barcode from the image.

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Looks like the original QuaggaJS is no longer actively maintained.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!)
