toggleClass() - piotrbadelek/hQuery GitHub Wiki

The toggleClass function toggles a class. For example, if a element has a class, it will delete that class - but if a element does not have a class, the class will be added

h("h1").toggleClass("badge"); // toggles a badge class
h("h1").toggleClass("badge", "badge-normal", "hero"); // toggles 3 classes (badge, badge-normal and hero)
