class method Element.descendants
Element.descendants(element) → [Element…]
Collects all of the element's descendants (its children, their children,
etc.) and returns them as an array of extended elements. As with all of
Prototype's DOM traversal methods, only Element
s are returned, other
nodes (text nodes, etc.) are skipped.
This method can be called either as an instance method or as a generic method. If calling as a generic, pass the instance in as the first argument.
