Capybara testing ignores javascript

I like to use code like
Login
which, when clicked, would trigger a jQuery action defined in my
application.js file to toggle the display of a div somewhere (in this
case, a div that is a partial for a login form).

But click_link “Login” fails to recognize this kind of anchor tag!

Worse, would Capybara even catch the new div that was originally
hidden because it was like

...

So I’m having lots of trouble defining a step definition in which all
I want to do is login. It would be like what’s at the bottom of this
page: GitHub - cucumber/common: A home for issues that are common to multiple cucumber repositories … but
the issue with click_link has stopped me.

Thanks in advance…
