CharacterData: after() method

The after() method of the CharacterData interface inserts a set of Node objects or strings in the children list of the object's parent, just after the object itself.

Strings are inserted as Text nodes; the string is being passed as argument to the Text() constructor.

Syntax

js

after(...nodes)

Parameters

nodes

A set of Node or strings to insert.

Exceptions

HierarchyRequestError DOMException

Thrown when the new nodes cannot be inserted at the specified point in the hierarchy, that is if one of the following conditions is met:

Examples

The after() method allows you to insert new nodes after a CharacterData node.

js

const h1TextNode = document.querySelector("h1").firstChild;
h1TextNode.after(" #h1");

h1TextNode.parentElement.childNodes;
// NodeList [#text "CharacterData.after()", #text " #h1"]

h1TextNode.data;
// "CharacterData.after()"

Note: If you rather want to append text to the current node, the appendData() method lets you append to the current node's data.
