I want to create a member login form using Ajax to post to my login controller. As it's in a partial view invoked from my site master, I'll need to specify the controller name. But there isn't an overload that has a controllerName parameter.

I've attempted to do it be specifying the Url to post to in the AjaxOptions. However, it doesn't work: when I click the submit button, it just reloads whatever page I am on.
