addEventListener

Adds an event listener to node. See the MDN Reference for more details.

Signature

export declare const addEventListener: (
  event: string,
  listener: EventListenerOrEventListenerObject,
  options?: boolean | AddEventListenerOptions | undefined,
) => (node: Node) => IO.IO<void>;

Added in v1.0.0

appendChild

Signature

export declare const appendChild: (
  child: Node,
) => (parent: Node) => IO.IO<Node>;

Added in v1.0.0

contains

Returns an IO of true if child is an inclusive descendant of parent, and an IO of false otherwise.

Signature

export declare const contains: (
  child: Node,
) => (parent: Node) => IO.IO<boolean>;

Added in v1.0.0

createDocumentFragment

Creates a new document.

Signature

export declare function createDocumentFragment(): IO.IO<DocumentFragment>;

Added in v1.0.0

createElement

Creates an instance of the element for the specified tag.

Signature

export declare function createElement<K extends keyof HTMLElementTagNameMap>(
  tagName: K,
  options?: ElementCreationOptions,
): IO.IO<HTMLElementTagNameMap[K]>;

Added in v1.0.0

createTextNode

Creates a text string from the specified value.

Signature

export declare function createTextNode(data: string): IO.IO<Text>;

Added in v1.0.0

getElementById

Returns a reference to the first object with the specified value of the ID attribute within the document param.

Signature

export declare const getElementById: (
  document: Document,
) => (id: string) => IOO.IOOption<HTMLElement>;

Added in v1.0.0

removeAttribute

Signature

export declare const removeAttribute: (
  attribute: string,
) => (element: HTMLElement) => IO.IO<void>;

Added in v1.0.0

removeChild

Returns a IOO.none if child is not contained within parent. If it is contained, the child is removed from the within the parent and returned within an IOO.some.

Signature

export declare const removeChild: (
  child: Node,
) => (parent: Node) => IOO.IOOption<Node>;

Added in v1.0.0

removeEventListener

Removes the event listener in node’s event listener list with the same type, callback, and options.

Signature

export declare const removeEventListener: (
  event: string,
  listener: EventListenerOrEventListenerObject,
  options?: boolean | EventListenerOptions | undefined,
) => (node: Node) => IO.IO<void>;

Added in v1.0.0

replaceChild

Returns a IOO.none if oldChild is not contained within parent. If it is contained, oldChild is replaced by newChild and returned within an IOO.some.

Signature

export declare const replaceChild: (
  newChild: Node,
  oldChild: Node,
) => (parent: Node) => IOO.IOOption<Node>;

Added in v1.0.0

setAttribute

Sets the value of element’s first attribute whose qualified name is attribute to value.

Signature

export declare const setAttribute: (
  attribute: string,
  value: string,
) => (element: HTMLElement) => IO.IO<void>;
