how to toggle attr() in jquery

Question

I have a simple add attribute function:

$(\".list-toggle\").click(function() {
    $(\".list-sort\").attr(\'colspan\', 6);
});

My question is:

Answer 1

This would be a good place to use a closure:

(function() {
  var toggled = false;
  $(".list-toggle").click(function() {
    toggled = !toggled;
    $(".list-sort").attr("colspan", toggled ? 6 : null);
  });
})();

The toggled variable will only exist inside of the scope defined, and can be used to store the state of the toggle from one click event to the next.
