Decoding a 2d barcode decoding matrix in HTML / JavaScript (Android)

Context: I need to scan the barcode of a data matrix with the camera of my Android mobile phone. I access the camera via html5 and got the image into the canvas element.

Approach: I cannot find a javascript library to scan an image to decode a 2D matrix data code. Actually, I call the ZXing application and copy and return, etc. Therefore, I am not satisfied with this laborious decision.

Question: Does anyone know a javascript library for decoding two-dimensional data matrix codes? Or maybe a simple solution using another application, such as ZXing / Goggles, and get the scan result automatically in JS ?!

I would be grateful for your contribution.
