The DocumentFragment.querySelectorAll()
method returns a NodeList
of elements within the DocumentFragment
(using depth-first pre-order traversal of the document's nodes) that matches the specified group of selectors.
If the selectors specified in parameter are invalid a DOMException
with a SYNTAX_ERR
value is raised.
querySelectorAll(selectors)
A non-live NodeList
containing one Element
object for each element that matches at least one of the specified selectors or an empty NodeList
in case of no matches.
This example returns a list of all div
elements within the DocumentFragment
with a class of either "note
" or "alert
":
const matches = documentfrag.querySelectorAll("div.note, div.alert");
