DocumentFragment: replaceChildren() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2020.
The DocumentFragment.replaceChildren() method replaces the
existing children of a DocumentFragment with a specified new set of children. These
can be string or Node objects.
Syntax
js
replaceChildren(param1)
replaceChildren(param1, param2)
replaceChildren(param1, param2, /* …, */ paramN)
Parameters
param1, …,paramN-
A set of
Nodeobjects or strings to replace theDocumentFragment's existing children with. If no replacement objects are specified, then theDocumentFragmentis emptied of all child nodes.
Return value
None (undefined).
Exceptions
HierarchyRequestErrorDOMException-
Thrown when the constraints of the node tree are violated.
Examples
Emptying a document fragment
replaceChildren() provides a very convenient mechanism for emptying a document fragment
of all its children. You call it on the document fragment without any argument specified:
js
let fragment = new DocumentFragment();
let div = document.createElement("div");
let p = document.createElement("p");
fragment.append(p);
fragment.prepend(div);
fragment.children; // HTMLCollection [<div>, <p>]
fragment.replaceChildren();
fragment.children; // HTMLCollection []
