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.
Members
# classList
Allows for manipulation of element's class content attribute as a set of whitespace-separated tokens through a DOMTokenList object.
# closest
Returns the first (starting at element) inclusive ancestor that matches selectors, and null otherwise.
# getAttribute
Returns element's first attribute whose qualified name is qualifiedName, and null if there is no such attribute otherwise.
# getAttributeNames
Returns the qualified names of all element's attributes. Can contain duplicates.
# getAttributeNS
Returns element's attribute whose namespace is namespace and local name is localName, and null if there is no such attribute otherwise.
# getElementsByClassName
Returns 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.
# hasAttribute
Returns true if element has an attribute whose qualified name is qualifiedName, and false otherwise.
# hasAttributeNS
Returns true if element has an attribute whose namespace is namespace and local name is localName.
# matches
Returns true if matching selectors against element's root yields element, and false otherwise.
# removeAttributeNS
Removes element's attribute whose namespace is namespace and local name is localName.
# requestFullscreen
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.
# setAttribute
Sets the value of element's first attribute whose qualified name is qualifiedName to value.
# setAttributeNS
Sets the value of element's attribute whose namespace is namespace and local name is localName to value.
# shadowRoot
Returns element's shadow root, if any, and if shadow root's mode is "open", and null otherwise.
# toggleAttribute
If 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.
