Creates an instance of UnderrunEvent.
The number of frames that were not processed due to the underrun.
ReadonlyAT_ReadonlybubblesThe bubbles read-only property of the Event interface indicates whether the event bubbles up through the DOM tree or not.
ReadonlyBUBBLING_ReadonlycancelableThe cancelable read-only property of the Event interface indicates whether the event can be canceled, and therefore prevented as if the event never happened.
The cancelBubble property of the Event interface is deprecated.
ReadonlyCAPTURING_ReadonlycomposedThe read-only composed property of the or not the event will propagate across the shadow DOM boundary into the standard DOM.
ReadonlycurrentThe currentTarget read-only property of the Event interface identifies the element to which the event handler has been attached.
ReadonlydefaultThe defaultPrevented read-only property of the Event interface returns a boolean value indicating whether or not the call to Event.preventDefault() canceled the event.
ReadonlyeventThe eventPhase read-only property of the being evaluated.
ReadonlyframeThe number of frames that were not processed due to the underrun.
ReadonlyisThe isTrusted read-only property of the when the event was generated by the user agent (including via user actions and programmatic methods such as HTMLElement.focus()), and false when the event was dispatched via The only exception is the click event, which initializes the isTrusted property to false in user agents.
ReadonlyNONEThe Event property returnValue indicates whether the default action for this event has been prevented or not.
ReadonlysrcThe deprecated Event.srcElement is an alias for the Event.target property.
ReadonlytargetThe read-only target property of the dispatched.
ReadonlytimeThe timeStamp read-only property of the Event interface returns the time (in milliseconds) at which the event was created.
ReadonlytypeThe type read-only property of the Event interface returns a string containing the event's type.
Static ReadonlyAT_Static ReadonlyBUBBLING_Static ReadonlyCAPTURING_Static ReadonlyNONEStatic ReadonlytypeThe composedPath() method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked.
The composedPath() method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked. This does not include nodes in shadow trees if the shadow root was created with its ShadowRoot.mode closed.
The preventDefault() method of the Event interface tells the user agent that if the event does not get explicitly handled, its default action should not be taken as it normally would be.
The preventDefault() method of the Event interface tells the user agent that the event is being explicitly handled, so its default action, such as page scrolling, link navigation, or pasting text, should not be taken.
The stopImmediatePropagation() method of the If several listeners are attached to the same element for the same event type, they are called in the order in which they were added.
The stopImmediatePropagation() method of the Event interface prevents other listeners of the same event from being called.
The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases.
The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed. If you want to stop those behaviors, see the preventDefault() method. It also does not prevent propagation to other event-handlers of the current element. If you want to stop those, see stopImmediatePropagation().
Represents a custom event indicating that an underrun occurred in the audio processing. UnderrunEvent is triggered not at the moment the underrun occurs, but when the underrun is resolved or just before the node stops.
