KeyboardEvents
Properties
action string
action of the KeyboardEvent
bubbles boolean
Returns true or false depending on how event was initialized. True if event goes through its target’s ancestors in reverse tree order, and false otherwise.
cancelable boolean
Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.
composed boolean
Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.
currentTarget EventTarget|null
Returns the object whose event listener’s callback is currently being invoked.
defaultPrevented boolean
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
eventPhase number
Returns the event’s phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
isTrusted boolean
Returns true if event was dispatched by the user agent, and false otherwise.
target EventTarget|null
Returns the object to which event is dispatched (its target).
timeStamp number
Returns the event’s timestamp as the number of milliseconds measured relative to the time origin.
type string
Returns the type of event, e.g. “click”, “hashchange”, or “submit”.
Methods
composedPath
Returns the invocation target objects of event’s path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root’s mode is “closed” that are not reachable from event’s currentTarget.
Returns EventTarget[]
preventDefault
If invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.
Returns void
stopImmediatePropagation
Invoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.
Returns void
stopPropagation
When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.
Returns void
