jQuery jQuery.contains()

Learn all about the jQuery function jQuery.contains().

The $.contains() method returns true if the DOM element provided by the second argument is a descendant of the DOM element provided by the first argument, whether it is a direct child or nested more deeply. Otherwise, it returns false. Only element nodes are supported; if the second argument is a text or comment node, $.contains() will return false.

Note: The first argument must be a DOM element, not a jQuery object or plain JavaScript object.
