closest()
This function gets the first parent element that matches a selector, by testing the element itself
and traversing up through its ancestors in the DOM tree. (In HTML, a parent is an element that
contains another element.)
The function can be used for:
l The elements that match the selector of a script (see "results" on page1448).
l One element that matches the selector of a script that runs for "Each matched element"
(see "this" on page1364 and "Setting the scope of a script" on page883).
l The elements returned by a query in the template (see "query()" on page1319).
To get a child element or all child elements, use children() (see "children()" on page1379).
The closest() command is based on the closest() command found in the jQuery library:
https://api.jquery.com/closest/.
To get an element's sibling element, you can use "prev()" on page1397 or "next()" on
page1390.
