This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The ChildNode.after() method inserts a set of Node or DOMString objects in the children list of this ChildNode's parent, just after this ChildNode. DOMString objects are inserted as equivalent Text nodes.
Syntax
[Throws, Unscopable] void ChildNode.after((Node or DOMString)... nodes);
Parameters
Exceptions
HierarchyRequestError: Node cannot be inserted at the specified point in the hierarchy.
Examples
Inserting an element
var parent = document.createElement("div");
var child = document.createElement("p");
parent.appendChild(child);
var span = document.createElement("span");
child.after(span);
console.log(parent.outerHTML);
// "<div><p></p><span></span></div>"
Inserting text
var parent = document.createElement("div");
var child = document.createElement("p");
parent.appendChild(child);
child.after("Text");
console.log(parent.outerHTML);
// "<div><p></p>Text</div>"
Inserting an element and text
var parent = document.createElement("div");
var child = document.createElement("p");
parent.appendChild(child);
var span = document.createElement("span");
child.after(span, "Text");
console.log(parent.outerHTML);
// "<div><p></p><span></span>Text</div>"
ChildNode.after() is unscopable
The after() method is not scoped into the with statement. See Symbol.unscopables for more information.
