[jQuery] hover stoppropagation?

[jQuery] hover stoppropagation?


im sorry if im posting duplicate, but iv searched for a long while..
I have nested dom and have script:
        function startVisualAid(){
            $(".holder > *").hover(
                function(){
                    $(this).parents(".hover_this").trigger('mouseleave').removeClass
("hover_this");
                    $(this).addClass("hover_this");
                },
                function(){
                    $(this).removeClass("hover_this");
                    $(this).parents().trigger('mouseenter');
                }
            );
        }
this basically works like what i want - add class to a single hovered
item only, not its parents. but things are just getting very slow when
i have a deeply nested doms. I think there must be more simple and
fast way to do this, but i dont know how the stopPropagation thing
work on the hover event. thanks a lot!
