Hide/show element with a boolean
Apparently you can just pass a boolean to the toggle function
$element.toggle(shouldElementBeVisible)
Yes there is!
$element.toggle();
Without any parameters, toggle just toggles the elements visibility (I don't mean the visibility property) and depends on the current state of the element.
$element.toggle(display);
If you call toggle with a boolean parameter, element is shown if it is true and hidden if it is false

jQuery has toggle: http://api.jquery.com/toggle/
$element.toggle();
This will show the element if it's hidden, and hide it if it's shown.
