    Interface Element

    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.

    Accessors

    • get classList(): DOMTokenList

      Allows for manipulation of element's class content attribute as a set of whitespace-separated tokens through a DOMTokenList object.

      MDN Reference

      Returns DOMTokenList

    • set classList(value: string): void

      Parameters

      • value: string

      Returns void

    • get part(): DOMTokenList

      MDN Reference

      Returns DOMTokenList

    • set part(value: string): void

      Parameters

      • value: string

      Returns void

    Methods

    • 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.

      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.
