Need help refactoring this Javascript if/else statement

Here's my current if/else statement:

var current_class = $(this).closest("article").attr("class")

if (current_class == 'opened')
{
  $(this).closest("article").removeClass('opened');
  $(this).closest("article").addClass('closed');
}
else
{
  $(this).closest("article").removeClass('closed');
  $(this).closest("article").addClass('opened');
}

Is there a shorter way to write all of that? Just seems...overweig开发者_如何转开发ht. :)

Use

.toggleClass()

Here is an example http://api.jquery.com/toggleClass/

IMO this is the cleanest and still clearest solution:

var current_class = $(this).closest("article");
if (current_class.hasClass('opened'))
{
  current_class.removeClass('opened').addClass('closed');
}
else
{
  current_class.removeClass('closed').addClass('opened');
}

maybe something like:

var current = $(this).closest('article'); // no need to run the selector over and over
var current_class = current.attr('class');
current.removeClass('opened closed').addClass(current_class=='opened'?'closed':'opened');

---

$(this).closest("article").toggleClass('opened').toggleClass('closed');
