Methods

append

  • append(...nodes: (string | Node)[]): void

  • Inserts nodes after the last child of node, while replacing strings in nodes with equivalent Text nodes.

    Returns void

prepend

  • prepend(...nodes: (string | Node)[]): void

  • Inserts nodes before the first child of node, while replacing strings in nodes with equivalent Text nodes.

    Throws a "HierarchyRequestError" DOMException if the constraints of the node tree are violated.

    Parameters

    • Rest ...nodes: (string | Node)[]

    Returns void

querySelector

  • Returns the first element that is a descendant of node that matches selectors.
