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:

• If the insertion of one of the added node would lead to a cycle, that is if one of them is an ancestor of this CharacterData node.
• If one of the added node is not a DocumentFragment, a DocumentType, an Element, or a CharacterData.
• If this CharacterData node is actually a Text node, and its parent is a Document.
• If the parent of this CharacterData node is a Document and one of the nodes to insert is a DocumentFragment with more than one Element child, or that has a Text child.

Examples

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

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

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

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