Effects with 2 divs and after one only function

Effects with 2 divs and after one only function

My problem is simply.

I have 2 divs with class="a" and take them: var div_elements = $("div.a");

Then I start an effect: div_elements.fadeOut(300, function() { alert(1); });

OK.

But I only want to make 1 alert, not 2.

How can I make only a one function after than execute a 2 divs with a 2 effects???

Thank's a lot!
