[jQuery] IS condition true like an if statement?

[jQuery] IS condition true like an if statement?


I'm trying to create a link that when clicked will produce an alert if
there are any visible divs (all .detail divs are hidden by default).
I have the following function but it doesn't seem I'm doing it
correctly; nothing happens regardless of the visibility status of the
divs.
$("a.saveConfig").click(function() {
            $('div.detail').is(':visible'), (function () {
    alert('Hey this works');
         });
});
Is there a better way to do an if statement using JQuery selectors or
is there something I'm missing in my code?
