[jQuery] click function

[Alfredo Alessandrini]

I've a simple question..

I'm writing a function that call an event on first mouse click and
call another event on second mouse click.

But I've some problem, because work only the first mouse click:

jQuery(document).ready(function() {
$(".menu a").click(function() {
    $(this).next("em").animate({opacity: "show", top: "-205"}, "slow");

    $(this).next("em").animate({opacity: "hide", top: "-205"}, "fast");

        });

});

Any help.. :-)

Thanks in advance,

Alfredo
