Is it possible to prevent my browser from executing links or callbacks?

I am a the moment working on an old spaghetti website on which I would like to know what happens when I click on something.

The code really isn't clear, and If I disallow javascript, it blocks everything.

Chrome javascript debugger allows me to step through code once there is breakpoints, which I have no idea where to place.

But both of these solutions doesn't prevent things from happening if I click on a link (and that is expected behavior).

So, is there a way to "catch" where code is ran when 'start recording' has been triggered ? And the same way, "catch" redirections (from links as well as from window.location changing).
