It depends on what the JS script does. If it draws a menu for example, it won't be accessible, but if it just hides/shows a div with menu elements, it would be accessible in some cases, but probably not for all the screen readers.
For just showing a confirmation window, JS is accessible for the screen readers.

The most annoying thing however is to use links that use JS code in the href attribute instead of associate it with the events like onClick.
This is because when the user makes a shift+click or shift+enter on a link in order to open the new page in a new window, it just displays an error because the browser can't access an url like
javascript:DoPostBack()

It is also very annoying to need to open a link like "#" or "".

I think that if the user presses shift+enter, he knows that this will open the page in a new window, so the href attribute should contain the full URL to the targeted page.
Of course, if the URL should change something on the server, that page that opens directly (without JS) should contain a form that asks for a confirmation.
