The KeyboardEvent type exposes the following members.
true if the Alt (alternative) (or "Option") key modifier was active. The un-initialized value of this attribute MUST be false.
Used to indicate whether or not an event is a bubbling event. If the event can bubble the value is true, else the value is false.(Inherited from Event.)
Used to indicate whether or not an event can have its default action prevented. If the default action can be prevented the value is true, else the value is false.(Inherited from Event.)
The code holds a string that identifies the physical key being pressed. The value is not affected by the current keyboard layout or modifier state, so a particular key will always return the same value.
true if the Control (control) key modifier was active. The un-initialized value of this attribute MUST be false.
Used to indicate the IEventTarget whose IEventListeners are currently being processed. This is particularly useful during capturing and bubbling.(Inherited from Event.)
Returns true if preventDefault() was invoked while the cancelable attribute value is true, and false otherwise.(Inherited from Event.)
Specifies some detail information about the Event, depending on the type of event.(Inherited from UIEvent.)
Used to indicate which phase of event flow is currently being evaluated.(Inherited from Event.)
true if the key event occurs as part of a composition session, i.e., after a compositionstart event and before the corresponding compositionend event. The un-initialized value of this attribute MUST be false.
The isTrusted attribute must return the value it was initialized to. When an event is created the attribute must be initialized to false.(Inherited from Event.)
The key holds the key value of the key pressed. If the value is has a printed representation, it MUST be a non-empty Unicode character string, conforming to the algorithm for determining the key value defined in this specification. If the value is a control key which has no printed representation, it MUST be one of the key values defined in the key values set, as determined by the algorithm for determining the key value. Implementations that are unable to identify a key MUST use the key value Unidentified.
The location attribute contains an indication of the logical location of the key on the device.
true if the meta (Meta) key modifier was active.
true if the key has been pressed in a sustained manner. Holding down a key MUST result in the repeating the events keydown, beforeinput, input in this order, at a rate determined by the system configuration. For mobile devices which have long-key-press behavior, the first key event with a repeat attribute value of true MUST serve as an indication of a long-key-press. The length of time that the key MUST be pressed in order to begin repeating is configuration-dependent.
true if the shift (Shift) key modifier was active.
Used to indicate the IEventTarget to which the event was originally dispatched.(Inherited from Event.)
Used to specify the time (in milliseconds relative to the epoch) at which the event was created. Due to the fact that some systems may not provide this information the value of timeStamp may be not available for all events. When not available, a value of 0 will be returned. Examples of epoch time are the time of the system start or 0:0:0 UTC 1st January 1970.(Inherited from Event.)
The name of the event (case-insensitive). The name must be an XML name.(Inherited from Event.)
The view attribute identifies the Window from which the event was generated. The un-initialized value of this attribute MUST be null.(Inherited from UIEvent.)
