.closest()

For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.

.prev()

Get the immediately preceding sibling of each element in the set of matched elements. If a selector is provided, it retrieves the previous sibling only if it matches that selector.

.find()

Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

.parentsUntil()

Get the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector, DOM node, or jQuery object.

.prevAll()

Get all preceding siblings of each element in the set of matched elements, optionally filtered by a selector, in the reverse document order.

.nextUntil()

Get all following siblings of each element up to but not including the element matched by the selector, DOM node, or jQuery object passed.

jQuery()

Return a collection of matched elements either found in the DOM based on passed argument(s) or created by passing an HTML string.

.is()

Check the current matched set of elements against a selector, element, or jQuery object and return true if at least one of these elements matches the given arguments.

.has()

Reduce the set of matched elements to those that have a descendant that matches the selector or DOM element.

.next()

Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.
