Check this JavaScript barcode scanner It's open source and free

Also you can check this JavaScript library https://github.com/EddieLa/BarcodeReader

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.
