in thread Executing JavaScript function using WWW::Mechanize::Firefox

Thanks, but that yields the error "MozRepl::RemoteObject: TypeError: 'alert' called on an object that does not implement interface Window. at test_js.pl line 23."

Also, my problem is that in my use case, I don't write the JavaScript myself -- I am trying to have Firefox use a website that has a couple of functions which I want to call.

    That is an important message and clue about the environment you're facing

    Also, my problem is that in my use case, I don't write the JavaScript myself -- I am trying to have Firefox use a website that has a couple of functions which I want to call.

    Can you get firefox to do that without involving perl ?

    Because browsers kind of go out of their way to forbid such tricks because of security issues

      Not sure I understand what kind of a clue this is. Can you elaborate?

      Manual operation of the website works just fine! And since ReplMoz is inside the browser, I should not be caught by the browser doing anything fishy, right?

      Here is what the actual link in the website I am facing looks like:

      <a href='#' onclick='goToPage(2);return false;'>Next &gt;</a>

      And yes, I know, I can click that link in a different way, but the thing is that I want to be able to tell it to which page it should go, i.e. I want to call goToPage with a parameter of my choosing.
