I have a jQuery element but I have to send it to a function that only accepts HTML elements. How can I convert the jQuery element to an HTML element?
$("#foo")[0] will get you an HTML element. Using brackets is a tiny bit faster than using .get() but not something you'll likely notice unless you are doing it millions of times.
Try myJQueryElement.get(0) or myJQueryElement[0]. (get() is most useful when you need negative indices, for example, as described in the documentation for get().)
