Your filter logic should be correct, Try using the confirm function, and using jQuery instead of $.

jQuery('a').filter(function() {

  }).click(function(e) {
       if(!confirm("You are about to proceed to an external website."))
       {
            // if user clicks 'no' then dont proceed to link.
            e.preventDefault();
       };
  });

I tried this out in dev tools on your site and it seems to work correctly if you use jQuery. I think you may have some plugin that is causing conflicts with $.
