Re^5: (OT) How to override the javascript alert when submitting a form using WWW::Mechanize::Firefox

There is no convenient way to detect window.alert() from WWW::Mechanize::Firefox. You can assign a dummy function to window.alert to override it. This will prevent alert boxes popping up until the next page load:

my $window= $mech->repl->expr('window');
$window->{alert}= sub {};
...

Alternatively, you can put the override into Javascript directly:

$mech->eval_in_page(<<'JS');
    window.alert= function() {};
