How do I run a page's javascript function?

Question

By expecting the html page's code I found that a given link calls updateAuthors('next'). Can I call it with pentadacyl?

There's execute and javascript (commands?) but inserting the above call after them and hittin return doesn't work.

Using the :javascript command should work if the function is global, however when you click a link there is additional context that is sent to the method that it may be expecting. Do you see any errors in the messages window when you run :javascript updateAuthors('next')? — heavyd, Mar 19, 2015 at 22:03
@heavyd: I do: ReferenceError: updateAuthors is not defined. But calling it in Firebug console works. I just don't want to open firebug. I think it might be possible in pentadactyl. — Adobe, Mar 19, 2015 at 22:16
Perhaps, try window.updateAuthors('next')? From reading the docs, it sounds like it should work. Can you access other elements on the page? window.location or windows.document fore example? — heavyd, Mar 19, 2015 at 22:21
@heavyd: it gives TypeError: window.updateAuthors is not a function. — Adobe, Mar 19, 2015 at 22:26

:js content.wrappedJSObject.updateAuthors('next')

as described here.

The Error Console and Web Console execute code in the page context. We don't.
