Event interface represents any event which takes place in the DOM; some are user-generated (such as mouse or keyboard events), while others are generated by APIs (such as events that indicate an animation has finished running, a video has been paused, and so forth). There are many types of event, some of which use other interfaces based on the main
Event itself contains the properties and methods which are common to all events.
Interfaces based on
Below is a list of interfaces which are based on the main
Event interface, with links to their respective documentation in the MDN API reference. Note that all event interfaces have names which end in "Event".
- Creates an
Eventobject, returning it to the caller.
- A Boolean indicating whether the event bubbles up through the DOM or not.
- A historical alias to
Event.stopPropagation(). Setting its value to
truebefore returning from an event handler prevents propagation of the event.
- A Boolean indicating whether the event is cancelable.
- A Boolean value indicating whether or not the event can bubble across the boundary between the shadow DOM and the regular DOM.
- A reference to the currently registered target for the event. This is the object to which the event is currently slated to be sent; it's possible this has been changed along the way through retargeting.
Nodes through which the event has bubbled.
- Indicates whether or not
event.preventDefault()has been called on the event.
- Indicates which phase of the event flow is being processed.
- The explicit original target of the event (Mozilla-specific).
- The original target of the event, before any retargetings (Mozilla-specific).
- A non-standard alternative (from old versions of Microsoft Internet Explorer) to
Booleanindicating whether the given event will bubble across through the shadow root into the standard DOM. This property has been renamed to
- A non-standard alias (from old versions of Microsoft Internet Explorer) for
- A reference to the target to which the event was originally dispatched.
- The time at which the event was created, in milliseconds. By specification, this value is time since epoch, but in reality browsers' definitions vary; in addition, work is underway to change this to be a
- The name of the event (case-insensitive).
- Indicates whether or not the event was initiated by the browser (after a user click for instance) or by a script (using an event creation method, like event.initEvent)
- Initializes the value of an Event created. If the event has already being dispatched, this method does nothing.
Event.preventBubble()Obsolete since Gecko 24
- Prevents the event from bubbling. Obsolete, use
Event.preventCapture()Obsolete since Gecko 24
- Obsolete, use
- Cancels the event (if it is cancelable).
- For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)
- Stops the propagation of events further along in the DOM.
- Non-standard. Returns the value of
The definition of 'Event' in that specification.
