ErrorEvent
class ErrorEvent
- readonly 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.
- readonly 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.
- readonly 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.
- readonly currentTarget: null | EventTarget
Returns the object whose event listener's callback is currently being invoked.
- readonly defaultPrevented: boolean
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
- readonly eventPhase: number
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
- readonly isTrusted: boolean
Returns true if event was dispatched by the user agent, and false otherwise.
- readonly timeStamp: number
Returns the event's timestamp as the number of milliseconds measured relative to the time origin.
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.
Sets the
defaultPreventedproperty totrueifcancelableistrue.Stops the invocation of event listeners after the current one completes.
