Node

[src]

§Properties

readonly childElementCount: number

[src]

readonly children: HTMLCollection

[src]

Returns the child elements.

readonly firstElementChild: Element | null

[src]

Returns the first child that is an element, and null otherwise.

readonly lastElementChild: Element | null

[src]

Returns the last child that is an element, and null otherwise.

§Methods

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

[src]

Inserts nodes after the last 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.

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

[src]

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.

querySelector<K extends keyof HTMLElementTagNameMap>(selectors: K): HTMLElementTagNameMap[K] | null

[src]

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

querySelector<K extends keyof SVGElementTagNameMap>(selectors: K): SVGElementTagNameMap[K] | null

[src]

querySelector<E extends Element = Element>(selectors: string): E | null

[src]

querySelectorAll<K extends keyof HTMLElementTagNameMap>(selectors: K): NodeListOf<HTMLElementTagNameMap[K]>

[src]

Returns all element descendants of node that match selectors.

querySelectorAll<K extends keyof SVGElementTagNameMap>(selectors: K): NodeListOf<SVGElementTagNameMap[K]>

[src]

querySelectorAll<E extends Element = Element>(selectors: string): NodeListOf<E>

[src]

replaceChildren(...nodes: (Node | string)[]): void

[src]

Replace all children of node with nodes, while replacing strings in nodes with equivalent Text nodes.

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