Event
The Event interface represents any event of the DOM. It contains common properties and methods to any event.
A lot of other interfaces inherits, directly or not, from this base interface:

Constructor
Event()(en-US)- Creates an
Eventobject.
Properties
This interface doesn't inherit any property.
Event.bubbles(en-US) Read only- A boolean indicating whether the event bubbles up through the DOM or not.
Event.cancelable(en-US) Read only- A boolean indicating whether the event is cancelable.
Event.currentTarget(en-US) Read only- A reference to the currently registered target for the event.
Event.defaultPrevented(en-US) Read only- Indicates whether or not
event.preventDefault()(en-US) has been called on the event. Event.eventPhase(en-US) Read only- Indicates which phase of the event flow is being processed.
Event.explicitOriginalTarget(en-US) Read only- The explicit original target of the event (Mozilla-specific).
Event.originalTarget(en-US) Read only- The original target of the event, before any retargetings (Mozilla-specific).
Event.target(en-US) Read only- A reference to the target to which the event was originally dispatched.
Event.timeStamp(en-US) Read only- The time that the event was created.
Event.type(en-US) Read only- The name of the event (case-insensitive).
Event.isTrusted(en-US) Read only- 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)
Methods
This interface doesn't inherit any method.
Event.initEvent()(en-US)- 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.stopPropagation(en-US) instead. Event.preventCapture()Obsolete since Gecko 24- Obsolete, use
event.stopPropagation(en-US) instead. Event.preventDefault()(en-US)- Cancels the event (if it is cancelable).
Event.stopImmediatePropagation()(en-US)- 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)
Event.stopPropagation()(en-US)- Stops the propagation of events further along in the DOM.
Event.getPreventDefault()- ?
