Invoking MouseOver using link_to tag ?

<%= link_to "TestingMouseOverEvents" , {:controller => "login", :action => "logout"}, {"onmouseover" => "jscode", "onmouseout" => "jscode"}%>

Having some difficulty doing this, I want to run a .rjs template on the mouseover event to show a hidden div, (and another on the mouse off to hide it) tho 'cause I have a block in to hide visible menus when one is removed I don't think I can put my stcript in the link.

Basically I can't find a way to reference the RJS template as part of the mouseover event.
