Can you get MAC address using JavaScript?

No you cannot get the MAC address in JavaScript, mainly because the MAC address uniquely identifies the running computer so it would be a security vulnerability. Now if all you need is a unique identifier, I suggest you create one yourself using some cryptographic algorithm and store it in a cookie.

Can you get MAC address from browser?

Use the browser's "About System" diagnostic page:
