NodeList

NodeList objects are collections of nodes, usually returned by properties such as Node.childNodes and methods such as document.querySelectorAll().

interface NodeList {

[index: number]: Node;

readonly length: number;

[[Symbol.iterator]](): IterableIterator<Node>;

entries(): IterableIterator<[number, Node]>;

forEach(callbackfn: (

value: Node,

key: number,

parent: NodeList,

) => void, thisArg?: any): void;

item(index: number): Node | null;

keys(): IterableIterator<number>;

values(): IterableIterator<Node>;

}

var NodeList: {

prototype: NodeList;

new (): NodeList;

};

§Index Signatures

[index: number]: Node

§Properties

readonly length: number

[src]

Returns the number of nodes in the collection.

§Methods

[[Symbol.iterator]](): IterableIterator<Node>

[src]

entries(): IterableIterator<[number, Node]>

[src]

Returns an array of key, value pairs for every entry in the list.

forEach(callbackfn: (

value: Node,

key: number,

parent: NodeList,

) => void, thisArg?: any): void

[src]

Performs the specified action for each node in an list.

@param callbackfn

A function that accepts up to three arguments. forEach calls the callbackfn function one time for each element in the list.

@param thisArg

An object to which the this keyword can refer in the callbackfn function. If thisArg is omitted, undefined is used as the this value.

item(index: number): Node | null

[src]

Returns the node with index index from the collection. The nodes are sorted in tree order.

keys(): IterableIterator<number>

[src]

Returns an list of keys in the list.

values(): IterableIterator<Node>

[src]

Returns an list of values in the list.
