  • The hidePopover() method of the HTMLElement interface hides a popover element (i.e., one that has a valid popover attribute) by removing it from the top layer and styling it with display: none.

    MDN Reference

    Returns void

  • The insertAdjacentHTML() method of the Element interface parses the specified input as HTML or XML and inserts the resulting nodes into the DOM tree at a specified position.

    MDN Reference

    Parameters

    Returns void

  • The insertAdjacentText() method of the Element interface, given a relative position and a string, inserts a new text node at the given position relative to the element it is called from.

    MDN Reference

    Parameters

    Returns void

  • The insertBefore() method of the Node interface inserts a node before a reference node as a child of a specified parent node.

    MDN Reference

    Type Parameters

    Parameters

    • node: T
    • child: Node | null

    Returns T

  • The isDefaultNamespace() method of the Node interface accepts a namespace URI as an argument. It returns a boolean value that is true if the namespace is the default namespace on the given node and false if not. The default namespace can be retrieved with Node.lookupNamespaceURI() by passing null as the argument.

    MDN Reference

    Parameters

    • namespace: string | null

    Returns boolean

  • The isEqualNode() method of the Node interface tests whether two nodes are equal. Two nodes are equal when they have the same type, defining characteristics (for elements, this would be their ID, number of children, and so forth), its attributes match, and so on. The specific set of data points that must match varies depending on the types of the nodes.

    MDN Reference

    Parameters

    • otherNode: Node | null

    Returns boolean

  • The isSameNode() method of the Node interface is a legacy alias the for the === strict equality operator. That is, it tests whether two nodes are the same (in other words, whether they reference the same object).

    MDN Reference

    Parameters

    • otherNode: Node | null

    Returns boolean

  • The lookupNamespaceURI() method of the Node interface takes a prefix as parameter and returns the namespace URI associated with it on the given node if found (and null if not). This method's existence allows Node objects to be passed as a namespace resolver to XPathEvaluator.createExpression() and XPathEvaluator.evaluate().

    MDN Reference

    Parameters

    • prefix: string | null

    Returns string | null

  • The lookupPrefix() method of the Node interface returns a string containing the prefix for a given namespace URI, if present, and null if not. When multiple prefixes are possible, the first prefix is returned.

    MDN Reference

    Parameters

    • namespace: string | null

    Returns string | null

  • The normalize() method of the Node interface puts the specified node and all of its sub-tree into a normalized form. In a normalized sub-tree, no text nodes in the sub-tree are empty and there are no adjacent text nodes.

    MDN Reference

    Returns 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.

    MDN Reference

    Parameters

    • ...nodes: (string | Node)[]

    Returns void

  • The releasePointerCapture() method of the Element interface releases (stops) pointer capture that was previously set for a specific (PointerEvent) pointer.

    MDN Reference

    Parameters

    • pointerId: number

    Returns void

  • The Element method removeAttribute() removes the attribute with the specified name from the element.

    MDN Reference

    Parameters

    • qualifiedName: string

    Returns void

  • The removeAttributeNS() method of the Element interface removes the specified attribute with the specified namespace from an element.

    MDN Reference

    Parameters

    • namespace: string | null
    • localName: string

    Returns void

  • The removeChild() method of the Node interface removes a child node from the DOM and returns the removed node.

    MDN Reference

    Type Parameters

    Parameters

    • child: T

    Returns T

  • The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.

    MDN Reference

    Type Parameters

    Parameters

    Returns void

  • The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener() from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.

    MDN Reference

    Parameters

    Returns void

  • 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.

    MDN Reference

    Parameters

    • ...nodes: (string | Node)[]

    Returns void

  • Replaces 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.

    MDN Reference

    Parameters

    • ...nodes: (string | Node)[]

    Returns void

  • The reportValidity() method of the HTMLFormElement interface performs the same validity checking steps as the checkValidity() method. In addition, for each invalid event that was fired and not canceled, the browser displays the problem to the user.

    MDN Reference

    Returns boolean

  • The HTMLFormElement method requestSubmit() requests that the form be submitted using a specific submit button.

    MDN Reference

    Parameters

    Returns void

  • The HTMLFormElement.reset() method restores a form element's default values. This method does the same thing as clicking the form's control.

    MDN Reference

    Returns void

  • The setAttribute() method of the Element interface sets the value of an attribute on the specified element. If the attribute already exists, the value is updated; otherwise a new attribute is added with the specified name and value.

    MDN Reference

    Parameters

    • qualifiedName: string
    • value: string

    Returns void

  • The setAttributeNS() method of the Element interface adds a new attribute or changes the value of an attribute with the given namespace and name.

    MDN Reference

    Parameters

    • namespace: string | null
    • qualifiedName: string
    • value: string

    Returns void

  • The setHTMLUnsafe() method of the Element interface is used to parse HTML input into a DocumentFragment, optionally filtering out unwanted elements and attributes, and those that don't belong in the context, and then using it to replace the element's subtree in the DOM.

    MDN Reference

    Parameters

    • html: string

    Returns void

  • The setPointerCapture() method of the Element interface is used to designate a specific element as the capture target of future pointer events. Subsequent events for the pointer will be targeted at the capture element until capture is released (via Element.releasePointerCapture() or the pointerup event is fired).

    MDN Reference

    Parameters

    • pointerId: number

    Returns void

  • The HTMLFormElement.submit() method submits a given .

    MDN Reference

    Returns void

  • The toggleAttribute() method of the Element interface toggles a Boolean attribute (removing it if it is present and adding it if it is not present) on the given element.

    Parameters

    • qualifiedName: string
    • Optionalforce: boolean

    Returns boolean
