$("<div/>").after("<span/>")
=> [ div, span ]
(calling after on a disconnected DOM node adds the nodes to the end of the jQuery set)
$("<div/>").before("<span/>")
=> [ span, div ]
(calling before on a disconnected DOM node adds the nodes to the beginning of the jQuery set)
$("div").add("span")
=> [ div, span, span, div, span ]
(results now come out in document order)
$("div").find("code").andSelf();
=> [ div, code, code ]
(results now come out in document order)
Same goes for .parents(), .nextAll(), .prevAll(), and .siblings().
Exception: .parents() will still return the results in reverse document order.
jQuery.data(elem)
=> { object of data }
(no longer returns the unique ID assigned to the node)
therefore require dequeue to always leave the element it has dequeued on
the queue.
- In the fx queue, a progress sentinel is added when a queue element
is dequeued.
- The sentinel is ignored when dequeue is called explicitly
- When adding a new element to the fx queue, queue() checks if
the progress sentinel is present. If not, it calls dequeue()
