KeyboardEvent

Returns the Unicode value of a character key pressed during a keypress event.

Note: Required especially in Gecko based browsers

Returns the current state of the specified modifier key.

The key value of the key represented by the event. If the value has a printed representation, this attribute's value is the same as the char attribute. Otherwise, it's one of the key value strings specified in Key values. If the key can't be identified, this is the string "Unidentified". See key names for the detail.

A system and implementation dependent numerical code identifying the unmodified value of the pressed key. This is usually the decimal ASCII (RFC 20) or Windows 1252 code corresponding to the key; see Virtual key codes for a list of Gecko's keyCode values. If the key can't be identified, this value is 0. Read only.

The location of the key on the keyboard or other input device. See the constants in the KeyboardEvent object.

true if the key is being held down such that it is automatically repeating

The altKey property indicates if the alt key was pressed (true) or not (false) when the event occurred.

A boolean indicating whether the event bubbles up through the DOM or not.

A boolean indicating whether the bubbling of the event has been canceled or not.

A boolean indicating whether the event is cancelable.

A Boolean value indicating whether or not the control key was down when the touch event was fired. Read only.

Identifies the current target for the event, as the event traverses the DOM. It always refers to the element the event handler has been attached to as opposed to event.target which identifies the element on which the event occurred.

Returns a boolean indicating whether or not event.preventDefault() was called on the event.

Detail about the event, depending on the type of event. Read only.

Indicates which phase of the event flow is currently being evaluated.

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)

The metaKey property indicates if the meta key was pressed (true) or not (false) when the event occurred.

Cancels the event if it is cancelable, without stopping further propagation of the event.

A Boolean value indicating whether or not the shift key was down when the touch event was fired. Read only.

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.

This property of event objects is the object the event was dispatched on. It is different than event.currentTarget when the event handler is called in bubbling or capturing phase of the event.

Returns the time (in milliseconds since the epoch) at which the event was created.

A view which generated the event. Read only.
