event.preventDefault() on first click then remove

Question

I have the default anchor disabled if it has a class subnav as shown in this fiddle.

I only want this disabled for the first click then I want the normal anchor function

Answer 1

This works well. The second click goes to the page...

$(".smallNavigation > ul > li > a").click(function (e) {

    $("ul.sub-menu").hide();
    $("ul.sub-menu", $(this).parent("li")).show();

    e.preventDefault();
    $(this).unbind(e);

}
