I tried following Google's example: https://developer.chrome.com/extensions/options.html
I immediately encountered the problem of the button and body trying to execute functions, so I attached listeners instead. Then, it's telling me that the options page isn't allowed to execute JS.
Either I didn't properly understand how to do that, or Chrome's documentation is entirely wrong.
How do you use JS in there? Or: can you point me in the direction of a proper tutorial.
