Readonly childReadonly childReturns the children.
Readonly childrenReturns the child elements.
Readonly classAllows for manipulation of element's class content attribute as a set of whitespace-separated tokens through a DOMTokenList object.
Returns the value of element's class content attribute. Can be set to change it.
Readonly clientReadonly clientReadonly clientReadonly clientReadonly firstReturns the first child.
Readonly firstReturns the first child that is an element, and null otherwise.
Returns the value of element's id content attribute. Can be set to change it.
Readonly isReturns true if node is connected and false otherwise.
Readonly lastReturns the last child.
Readonly lastReturns the last child that is an element, and null otherwise.
Readonly localReturns the local name.
Readonly namespaceURIReturns the namespace.
Readonly nextReturns the first following sibling that is an element, and null otherwise.
Readonly nextReturns the next sibling.
Readonly nodeReturns a string appropriate for the type of node.
Readonly nodeReturns the type of node.
Readonly ownerReturns the node document. Returns null for documents.
Readonly parentReturns the parent element.
Readonly parentReturns the parent.
Readonly partReadonly prefixReturns the namespace prefix.
Readonly previousReturns the first preceding sibling that is an element, and null otherwise.
Readonly previousReturns the previous sibling.
Readonly scrollReadonly scrollReadonly shadowReturns element's shadow root, if any, and if shadow root's mode is "open", and null otherwise.
Returns the value of element's slot content attribute. Can be set to change it.
Readonly tagReturns the HTML-uppercased qualified name.
Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.
The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.
When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.
When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.
When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.
If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.
The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.
Optional options: boolean | AddEventListenerOptionsOptional options: boolean | AddEventListenerOptionsInserts nodes just after node, while replacing strings in nodes with equivalent Text nodes.
Throws a "HierarchyRequestError" DOMException if the constraints of the node tree are violated.
Rest ...nodes: (string | Node)[]Optional options: number | KeyframeAnimationOptionsInserts 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.
Rest ...nodes: (string | Node)[]Creates a shadow root for element and returns it.
Inserts nodes just before node, while replacing strings in nodes with equivalent Text nodes.
Throws a "HierarchyRequestError" DOMException if the constraints of the node tree are violated.
Rest ...nodes: (string | Node)[]Returns the first (starting at element) inclusive ancestor that matches selectors, and null otherwise.
Returns a bitmask indicating the position of other relative to node.
Returns true if other is an inclusive descendant of node, and false otherwise.
Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.
Optional options: GetAnimationsOptionsReturns a HTMLCollection of the elements in the object on which the method was invoked (a document or an element) that have all the classes given by classNames. The classNames argument is interpreted as a space-separated list of classes.
Returns node's root.
Optional options: GetRootNodeOptionsReturns whether node and otherNode have the same properties.
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.
Rest ...nodes: (string | Node)[]Returns the first element that is a descendant of node that matches selectors.
Returns all element descendants of node that match selectors.
Removes the event listener in target's event listener list with the same type, callback, and options.
Optional options: boolean | EventListenerOptionsOptional options: boolean | EventListenerOptionsReplace 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.
Rest ...nodes: (string | Node)[]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.
Rest ...nodes: (string | Node)[]Displays element fullscreen and resolves promise when done.
When supplied, options's navigationUI member indicates whether showing navigation UI while in fullscreen is preferred or not. If set to "show", navigation simplicity is preferred over screen space, and if set to "hide", more screen space is preferred. User agents are always free to honor user preference over the application's. The default value "auto" indicates no application preference.
Optional options: FullscreenOptionsOptional options: ScrollToOptionsOptional options: ScrollToOptionsOptional arg: boolean | ScrollIntoViewOptionsOptional options: ScrollToOptionsIf force is not given, "toggles" qualifiedName, removing it if it is present and adding it if it is not present. If force is true, adds qualifiedName. If force is false, removes qualifiedName.
Returns true if qualifiedName is now present, and false otherwise.
Optional force: boolean
Element is the most general base class from which all objects in a Document inherit. It only has methods and properties common to all kinds of elements. More specific classes inherit from Element.
