nextAll() method, mainly used to obtain the specified element All elements of the next sibling of the element
nextUntil() method is mainly used to obtain the next sibling element of the specified element. This sibling element must be the same as the specified element and nextUntil( ) method to set elements between elements
prev() method, mainly used to obtain the upper level sibling elements of the specified element
prevAll() method, mainly used to obtain all sibling elements at the previous level of the specified element
prevUntil() method, mainly used to obtain the previous sibling element of the specified element, This sibling element must be an element between the specified element and the element set by the prevUntil() method
