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

You could use something as simple as self unbind in the click handler.

Something like

function stopEventOnce(event) {
  event.preventDefault();
  $(this).unbind('click',stopEventOnce);
  return false;
}
$(".subnav a").bind('click', stopEventOnce);
